Saline-Alkaline Soil Amelioration Microorganism
Microbiological agents were an effective method to improve saline-alkalized soil. There were too many salt and basic substances in the soil of saline-alkalized land, which limited the growth and development of crops. The effect of traditional improvement methods was limited, and the microorganisms could significantly improve the quality of saline-alkalized land and crop yield. The principle was to adjust the chemical properties of the soil and the structure of the microorganisms by introducing specific microorganisms, such as salt-tolerant bacteria and alkali-tolerant bacteria, to improve the soil conditions. These microorganisms could use the organic matter in the soil to degrade salt and alkali-based substances to reduce the degree of salinity and increase the soil's penetrability and water-holding capacity. Different saline-alkalized soil had different soil properties and composition of microorganisms, so the selection of microorganisms should be based on the specific situation. For example, salt-tolerant bacteria and halogenic fungi with salt-tolerant ability could be selected for high-salt saline-tolerant soil; and bacteria with alkali-adaptability such as alkali-tolerant bacteria and alkali-tolerant fungi could be selected for high-alkali-tolerant soil. When it was used, the soil was first prepared for weeding and ploughing, and then the microorganisms were mixed with an appropriate amount of water, evenly sprayed on the surface of the soil or directly applied to the soil, and then watered, covered, and managed according to the situation to promote its growth and reproduction. However, the improvement effect usually takes a certain amount of time to appear. During the use, attention should be paid to controlling the dosage and frequency of application to avoid excessive use of the microorganisms that would cause excessive reproduction or negative effects.

Reflection on the Teaching of the Deterioration of Alkaline Alkaline and Alkaline Alkaline
The following is a reflection on the possible existence of the teaching of the deterioration of soda and calcium dioxide: ** 1. Knowledge System Construction ** 1. ** Consecutive ** - In the process of teaching, more attention should be paid to the coherent construction of the knowledge system of the deterioration of the two substances. For example, when explaining the deterioration of soda ash, the reason for the deterioration (reaction with carbon dioxide in the air), the judgment of the deterioration product (carbon dioxide), and the degree of deterioration (partial deterioration or complete deterioration) needed to be clearly presented to the students. Similarly, for the deterioration of calcium hydrogen, it should also be systematically explained from the cause of deterioration to the conjecture of the composition after deterioration. - It could be done by setting up a chain of questions, such as,"Why does soda deteriorate? What kind of substance was produced after it went bad? How do you determine the degree of deterioration?" He guided the students to gradually understand the knowledge and strengthen the connection between the various knowledge points. 2. ** Comparisons and connections ** - It was necessary to strengthen the comparison and connection teaching of the knowledge of the deterioration of the two substances. The reason for the deterioration of both was the reaction with carbon dioxide in the air, but the chemical equation of the reaction and the nature of the product were different. - For example, there were many ways to test the quality of the soda ash, such as adding acid to produce gas, adding base or adding salt to produce precipitations. However, the method to test the quality of the soda ash was similar to that of the soda ash, such as adding salt to produce precipitations. In teaching, students should be guided to compare these methods and deepen their understanding of the knowledge of the deterioration of the two substances. 3. ** Consolidating basic knowledge ** - The lack of a solid review of the properties of the two substances might affect the student's understanding of the deterioration of the two substances. This was because when determining whether or not the quality of the two substances had deteriorated, the properties of the two substances needed to be used. - Before teaching, students should have a clear understanding of the properties of carbon dioxide (reaction with acid, reaction with base, reaction with salt) and carbon dioxide (water-resistant, reaction with acid, etc.). This way, students could better understand the experimental principles and operations when explaining the knowledge of the deterioration of the two substances. ** 2. Teaching methods ** 1. ** Experimental Teaching ** - Experimental teaching was very important in this part. If there was a lack of experimental demonstration or students 'experimental operation, it might be difficult for students to intuitively understand the deterioration process and test methods of the two substances. - For example, when explaining the test method of adding acid to produce gas after the deterioration of soda ash, it would be better to let the students see the phenomenon of bubbles through a live demonstration experiment than to simply explain the theory. For the exploration of the composition of the deteriorated calcium dioxide, simple experiments could also be designed for students to participate in. For example, adding diluted sulfuric acid to the deteriorated calcium dioxide sample, observing the phenomenon and analyzing the composition. 2. ** Heuristic Teaching ** - In the process of teaching, we should use more elicitation teaching methods. For example, when exploring the degree of deterioration of soda ash, don't tell the students how to test it directly. Instead, guide the students to think,"If the soda ash is partially deteriorated, what substances are there in the solution? How do you test these substances separately?" Through this method, the students 'thinking ability was stimulated, and they were allowed to actively participate in the process of exploring knowledge. - As for the conjecture of the composition of the deteriorated calcium dioxide, students could also propose possible components according to their knowledge, and then verify them through experiments to improve their enthusiasm and initiative in learning. ** 3. Evaluation of students 'learning effects ** 1. ** Reaction mechanism ** - It was very important to establish a more effective feedback mechanism. In the classroom, students should be informed of their knowledge of the deterioration of calcium and calcium hydrogen, such as through classroom questions and group discussions. - If the students were found to have doubts or difficulties in understanding, they should adjust their teaching strategies in time and re-explain the relevant knowledge points to ensure that the students could keep up with the teaching progress. 2. ** Homework and Practice ** - The design of assignments and exercises should be focused on targeting and layering. For the knowledge points of the deterioration of the calcium and calcium hydrogen, questions of different levels of difficulty had to be designed, from the basic causes of deterioration and the judgment of the products to the exploration of the complex degree of deterioration. - Through marking the homework, they could understand the weak links of the students. For example, some students might be prone to mistakes in the test method of partial deterioration of the lithium hydrogen, and some students might have difficulties in the composition analysis of the deteriorated calcium hydrogen. They could provide individual tutoring or collective explanation for these problems. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Microorganism Metabolizing Pathway
The main pathways of metabolism for microorganisms were as follows: ** 1. Ways related to fermentation ** 1. **EMP Path ** - It was roughly divided into two stages. The first stage was the preparation stage, which produced the intermediate metabolism of Glyceralde- 3 -Phosphorate, and the second stage was the oxidoreduction reaction, which synthesized ATP-and formed Pyruvate. In the process of glycolysis, 2 molecules of ATPare consumed for the fermentation of sugar, but 4 molecules of ATPare synthesized. For every 1 molecules of glucose that is oxided, 2 molecules of ATPare obtained. During the synthesis of two molecules of 1,3-diphosphorous estergly ceric acid, two molecules of NAD were reduced to NAC. Due to the limited supply of NAD in the cell, the reaction was maintained by reducing Pyruvate and re-oxidising NRAD to NAD. For example, in yeast cells, Pyruvate was reduced to alcohol and released CO2, and in the cells of the Lactobacteria, Pyruvate was reduced to actic acid. The EMP pathway could provide ATP-and-NOD-H for the physiological activities of microorganisms, and the intermediate products could provide carbon skeletons for anabolic metabolism. Under certain conditions, it could reverse the synthesis of glycan. 2. **HMP pathway ** - Starting from glucose- 6 -phosphorous acid, the final result of a cycle was that 1 molecular of glucose- 6 -phosphorous acid was converted into 1 molecular of glyceride- 3 -phosphorous acid, 3 molecular of carbon dioxide, and 6 molecular of dashing acid. Generally, it was not a energy-producing pathway, but rather a large amount of reducing power (ADPM) and intermediate metabolism products for biochemistry. For example, ribulose- 5 -phosphorous acid could be used to synthesize nuclear acid, some cozymes, and histines. It could also be converted to ribulose-1,5-bisphosphorous acid to fix CO2, which was of great significance to some microorganisms. The produced NRMPH could be produced through respiratory chain fermentation, but it was not the main way of metabolism. Most of the microorganisms had this pathway, and it often coexisted with the EMP pathway. 3. **ED pathway ** - When studying Pseudomonads glycophile, it was found that glucose- 6 -phosphorous acid was first dehydrated to produce gluconate- 6 -phosphorous acid, followed by the action of dehydrases and aldolases to produce one molecular glyceride- 3 -phosphorous acid and one molecular methyruvate. Then, glyceride- 3 -phosphorous acid entered the EMP pathway and was converted to methyruvate. One molecules of glucose would eventually produce two molecules of methyruvate, one molecules of Ang, and one molecules of NAC and NAC through the ED pathway. ** 2. Biological Oxidation Type ** 1. ** Fermenting ** - The microorganisms directly transferred the electrons released by the organic matter to some intermediate product of the incomplete fermentation of the organic matter. At the same time, they released energy and produced various metabolism products. Under the conditions of fermentation, the organic compound was only partially oxided and only a small part of the energy was released. The fermentation process was coupled with the reduction of the organic matter. The reduced organic matter came from the catabolism of the initial fermentation and did not require an external electron receptor. Fermentable substances included sugar, organic acid, and so on. Among them, the fermentation of glucose by microorganisms was the most important. 2. ** Breathing (Aerobic Breathing and Aerobic Breathing)** - It was a way for heterotrophs to catalyze organic matter. It was distinguished from fermentation based on the difference in the electron receptor in the oxido-reduction reaction. The process of breathing involved biological fermentation, which included the combination with oxygen, dehydration, or loss of electrons. The process could be divided into three stages: dehydration (or electrons), hydrogen transfer (or electrons), and hydrogen acceptance (or electrons). Its functions included energy production, reducing power production, and the production of small intermediate molecules. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Alkaline Sulphate and Trivalent Aluminium-Alkaline
When the reaction between the aluminum and the aluminum was completed, the aluminum was formed into aluminum and hydrogen. The reaction equation is: 2AI +6NaOx → 2AI (Ox)+3H ^. The reaction phenomenon was the production of gas and the formation of a white deposit (aluminum trioxid was a white powder). However, aluminum trioxides were amphoric trioxides and could not exist in a strong base environment. They would further react to form meta-aluminum aluminum. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Surface Microorganism Surveillance Method
For the monitoring method of microorganisms on the surface of the object, the disinfection machine for different purposes has different microorganisms test items according to the requirements of the standard WS628 - 2018 "technical requirements for the hygiene and safety evaluation of disinfection products" and "technical specifications for disinfection" 2002 edition. For example, in Class I disinfection products, if the label and instruction manual indicate that it is used for high-level disinfection of medical devices and supplies, the spore killing test of the spore of the mutant of the black fungus of the mutant of If it is not indicated, a quantitative sterilization test of M. chelonae plus a vegetative form of bacteria should be carried out. In the laboratory test, if the label and instruction manual indicate that the high-level disinfection of the telescope is required, the quantitative sterilization test of the spores of the spores of the mutants of the spores of the mutants of the spores of the spores For Class II disinfection products, the labels and instructions indicate that for medical devices and supplies that are used for low-level disinfection, the killing test of Staph. aureus, E. Coli, Pseudomonads aerulosa and candida alternans should be carried out. In addition, if the label and instruction manual indicate that it is used for disinfection of the surface of sanitary ware, it should be subjected to a quantitative disinfection test of candida whiteness; if it is indicated that it has a killing effect on fungi, it should be subjected to a quantitative disinfection test of aspergillum niger. In the hospital environment, the study concluded that routine microbiology monitoring was not recommended except during nocuous outbreak. There was currently no acceptable or proven standard to indicate that environmental pollution was associated with the risk of infection. There was no more general routine monitoring method for microorganisms on the surface of the organism, so he could not answer accurately. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Microorganism whole process management
The whole process management of microorganisms involves many aspects. The following are some of the main contents: ** I. Preservation and Management of Microorganisms ** 1. ** Preservation Institution and Target ** - For example, the General Microbiology Center of the China Committee for the Collection of Microorganisms was responsible for preserving various bacteria, fungi, yeast, and thread-like fungi other than animal pathogenic bacteria, as well as the plasmid-like organisms and single-celled algae strains that existed in the host cells. 2. ** Preservation process ** - ** Submit Materials **: The depository should submit two tubes of the culture of the microorganisms and attach a letter of request. The request must state that the microorganisms requested to be deposited are used for patent procedures, the name of the person requesting it or the name and address of the organization, and the conditions required for the cultivation, preservation, and survivability test of the microorganisms (When preserving a mixed culture of several microorganisms, the composition and at least one method to check the existence of each component should be stated), the classification and naming (with the name in the Latin-language) or identification symbols given by the petitioner to the preserved microorganisms, and a description of the characteristics of the microorganisms that are dangerous to health or the environment or a description that the petitioner does not know whether they have such characteristics. For foreigners who do not have a habitual residence or business office in China, they should go through the patent agency designated by the State Council. - ** Preservation method and responsibility **: The preservation center generally uses the method of freeze-drying or liquid nitrogen preservation. It is not responsible for reviewing the biological characteristics of the microorganisms requested for preservation. If the petitioners require a special preservation method or a re-examination of the biological characteristics and classification of the microorganisms, they should sign a separate contract with the preservation center when submitting the culture of the preserved microorganisms. - ** Preservation period and notification **: The preservation period of the preservation center is at least 30 years from the date of receipt of the microorganisms. After receiving a request to submit a sample of the microorganisms before the deadline, it should be preserved for at least five years. The preservation center shall, within one month from the date of receiving the culture of the microorganisms, conduct a survival test on the microorganisms requested for preservation. In addition to registering the test results with the preservation center, it shall also notify the person requesting the preservation and the patent office. - ** Preservation certificate and confidentiality **: When the preservation center receives the preservation request and the culture of the microorganisms, it shall give the person requesting it a written certificate, which shall include the name and address of the preservation institution, the name of the person requesting it or the name and address of the institution, the date of receipt of the culture of the microorganisms, the preservation number of the preserved microorganisms given by the preservation center, and the seal of the preservation center or the signature of the person in charge. During the preservation period, the preservation center shall be responsible for confidentiality and shall not provide any information and samples of the microorganisms to any third party. - ** Regulations on the provision of samples **: Before the patent application is rejected, withdrawn or deemed to be withdrawn, or before the patent right is granted, the preservation center shall only provide the samples of the microorganisms to the entities or individuals approved by the China patent office. After the patent application is rejected, withdrawn or deemed to be withdrawn, or after the patent right is granted, the preservation center shall provide the samples of the microorganisms to the entities or individuals designated by the person requesting the preservation of the microorganisms. When the preservation center provides the samples of the preserved microorganisms, it shall record in the register the name or the name and address of the requesting party who provides the samples of the microorganisms, the declaration that the requesting party guarantees not to transfer the microorganisms to any third party, the preservation number of the microorganisms provided and its brief description, and the date of providing the samples of the microorganisms. - ** Charging standard **: Storage fee (30 years) 1500 yuan; Survival report (per plant) 120 yuan; providing samples (per plant) 100 yuan; other payment standards are determined by the parties concerned. ** II. Microorganism Management in Human Health ** 1. ** Gut Microorganism Management ** - ** Effect of diet **: diet has a significant effect on the gut microflora. For example, different types of diet can cause changes in gut bacteria. The combination of omnivores, vegetarian food, meat food, and a diet containing probiotic yogurt would cause a great change in the composition of the gut bacteria community in the short term. Eating meat may cause a sharp decline in the number of certain bacteria that can reduce inflammation, while some bacteria related to obese may flourish. Eating fruits and vegetables can help maintain the balance of intestinal bacteria, and bacteria can also process plant fibers into short-chain fatty acid, which plays an important role in regulating physiological processes and maintaining the health of the intestine. - ** Dealing with the effects of antibiotics **: Antibiotic has a great impact on the gut bacteria. The use of antibiotics will indiscriminately kill harmful and beneficial bacteria, which may cause diarrhea, chronic inflammation, or intestinal disorder. If antibiotics must be used, probiotic bacteria should be supplemented during the period. Although it could not replace all the removed bacteria, it could temporarily fill the "vacuum" and prevent the invasion of bacteria. However, the effectiveness of probiotic bacteria in the intestines decreased rapidly with time. 2. ** Mouth Microorganism Management ** - [Food and oral hygiene: The balance of oral bacteria is related to eating habits.] The bacteria in the healthy mouth were rich in variety, while the bacteria in the unhealthy mouth were relatively simple. For example, streptococci mutans could break down sugar to produce acidic substances, while the red bacteria could cause inflammation. Too many of these two bacteria could lead to tooth decay, gum disease, and other problems. In severe cases, streptococci mutans could enter the bloodstream and cause rheumatism or endomyochondritis. Other bacteria in the healthy mouth can balance the power of these two types of bacteria. - ** oral hygiene measures **: Chewing sugar-free chewing gum can stimulate saliva secretion and help maintain oral hygiene. Chewing on the chewy gum is better because the chewy gum cannot be digested by harmful bacteria. It will accumulate in the body of the bacteria and cause them to die. 3. ** Skin Microorganism Management **: Overbathing is not conducive to the balance of skin microorganisms. Maintaining an appropriate cleaning frequency helps to maintain the stability of the skin's microflora. For example, wiping samples from underarms, cheeks, back, and feet after four days of not showering could identify hundreds of bacteria. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Alkaline reaction
The following is the reaction of some alklene under basic conditions: - In the nuclopathic epoxidation reaction, the electron deficient alkene could be epoxidized by hydrogen dioxide and tert-butoxyalcohol under basic conditions. Since the reaction was a nuclophile reaction, the epoxiidation could not proceed without an electron withdrawing group. - In the Julia-corona Asymmetrical Epoxidation Reaction, under the catalyst of the chiral-polyalpha-ammo acid, the electron deficient alkene was oxided by an oxidiser (hydrogen or ureido) under basic conditions to obtain a single configuration epoxide. - In the Payne Rearrangement Reaction, 2,3 -epoxy alcohol compounds are converted to 1,2 -epoxy- 3 -ol under basic conditions. This reaction is also known as the epoxy migration reaction. - In the laboratory, the reaction of the lithium salt and the lithium ether could be carried out under basic conditions. The lithium ether had an important catalyst activity in the reaction of alkene and the carbonylating reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Alkaline in the fountain
There were the following main reasons for the fountain's anti-alkalization: 1. The stone itself contains an alkali-like substance. For example, marble, granite, and other stone materials themselves contain a certain amount of alkali-like substance. These alkali-like substances will be deposited on the surface of the stone after dissolving in water, resulting in alkali-like phenomenon. 2. Alkaline substances in the water source: The water source of the fountain may contain a certain amount of alkaline substances, such as calcium and calcium ions in the underground water. When water comes into contact with the stone, the basic substances in the water will react with the acidic substances on the surface of the stone, producing an basic deposit, causing the phenomenon of alkalization. 3. External environmental factors: The fountain is often in an outdoor environment and is affected by natural factors such as sunlight and rain. Ultraviolet rays in the sun and acidic substances in the rain may cause damage to the surface of the stone, which may lead to the phenomenon of alkalization. In order to solve the problem of the fountain stone returning to the base, the following treatment methods can be adopted: 1. Cleaning the surface of the stone: Regular cleaning of the surface of the fountain stone is one of the important measures to prevent alkalization. It can be cleaned with a neutral cleaner and a soft brush to remove dirt and basic deposits on the surface of the stone. It can also be cleaned with a stone cleaning agent, such as the stone cleaning agent 306 of Zhongsinuo. It is a water-dissolved liquid that will neutralize the basic substances in the alkali-returning process. After 10 minutes, the stone surface can be cleaned with clean water and naturally dried without damaging the stone surface. 2. Acid washing treatment: For stone materials that have appeared alkali-returning phenomenon, the acid washing treatment method can be used. Acid washing could neutralize the alkali-like substance on the surface of the stone and dissolve it. However, it should be noted that the acid washing process should be carried out by professionals to avoid secondary damage to the stone. 3. Surface protection treatment: In order to prevent the surface of the stone material from returning to the alkali-like phenomenon again, the surface protection treatment can be carried out. Common protective methods include the use of alkali-resistant agents, waterproof agents, etc. After cleaning the alkali-returning substances on the surface, you can also directly apply the stone protective agent Sino - 1250 after drying the stone. You must apply it at least twice (the first time after the surface is dry). After the protective coating, you must not come into contact with rain for 24 hours. These protective agents could penetrate into the surface of the stone to form a protective film to prevent the deposit of alkali-based substances. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
