What are the methods for the management of microorganisms?

There were several methods to control the microorganisms: 1. [Single spore separation method: Single spores germinate to form a fungus to obtain a pure strain.] 2. ** tissue separation method **: Use the fungus or flesh tissue to separate and cultivate to obtain pure bacteria. 3. ** High-temperature mutation method **: Mutate the strain under high-temperature conditions to obtain a strain with excellent characteristics. 4. ** Radiation Mutation Method **: Use rays to mutate the strain to obtain a strain with excellent characteristics. 5. Protoplasts fusion method: The protoplasts of different strains are fused together to form a new hybrid strain. This method could combine the excellent traits of different strains, but it required high technical requirements and was difficult to operate. The operation steps included separating the protoplasts of different strains, fusing the protoplasts, and selecting the strains that grew well and had typical morphological characteristics for rejuvenation. Before the rejuvenation of the strain, the purification and identification of the strain should be done well. During the rejuvenation process, the cultivation conditions should be strictly controlled to ensure the healthy growth of the strain. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Explanation of Biological Detection Methods in Microorganisms

Biological detection was a method used to study the absorption, distribution, secretion, and metabolism of protein or protein drugs in animals or humans. Since protein and peptide-based drugs were mostly substances with biological activity, and the biological activity was not only determined by the primary structure of the drug, but also closely related to the secondary and tertiary structures, the biological detection method was a unique and necessary method to study the dynamics of this kind of drug. It had two purposes. One was to directly measure the concentration of drugs in body fluids, and the other was to identify the biological activity of the labeled drugs. This method could be divided into two categories: in body analysis and in body tissue (cell) analysis. There were also methods established according to the different biological activities of various protein and peptide-based methods.(For example, the in rabbit experiment of mobilizing the IL8 to mobilize a large number of neutrons from the bone was established based on the nature of the IL8.) The analysis of isolated tissues (cells), such as the method of stimulating the growth of chicken Dorsal Root Ganglion by nerve growth factor and the method of isolated rat uterus by pitocin, etc. With the development of molecular biology, cell culture has become a common method. The specific operation is based on the different interaction mechanism between protein and cell, such as the method of cell reproduction, the method of inhibition of reproduction, the method of reducing cell damage, etc. These methods mostly take the increase or decrease of cell number as the dose-effect index. The counting methods include direct counting method and indirect counting method. In addition, there were also detection methods based on the indirect interaction between protein and cells, such as the antibody-induced method combined with the immune detection, and the element-induced decomposition method combined with the reaction of the protein and the cell. However, there were some shortcomings in the bio-detection method, such as the inability to determine the small active mutants, the inability to trace the dynamic changes in the body, the interference of the sample by the serum's intrinsic substances, the reduction of sensitivity due to the threshold amount of cell factors required to start the biological process, and the long-term cultivation of the dependent cell strain that was easy to mutate and affect the detection of the detection. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Study on the Methods of High-efficient Selection and Characteristic Evaluation of Function Microorganisms

The efficient screening and characteristic evaluation methods of functional microorganisms included the following aspects: ###1. An efficient screening method 1. ** Analysis of background information ** - First of all, the site investigation report had to be analyzed to determine the type, content, and distribution information of the soil target contamination. This was the basis of the screening work. A clear target would help to screen out suitable functional microorganisms in the future. 2. ** Sampler ** - After choosing the appropriate location, he took a sample of the representative soil. After the samples were collected, they were placed in clean kraft paper or plastic bags, tied up and marked. At the same time, information such as the time, location, and environmental conditions of the samples were recorded for subsequent investigation. 3. ** Transportation and Storage of the samples ** - The samples were transported and stored at 4°C for no more than 7 days to ensure that the activity and characteristics of the microorganisms in the samples were not affected as much as possible. 4. ** preparation of bacteria suspension ** - Take 10g of soil sample into a 250mL conical flask, add 90mL of Deionized Water, and shake it in a constant temperature incubator (temperature 30°C, rotation speed 180r·min - 1) for 24 hours to make a bacteria suspension. After standing still, take the supernate as the separation and screening sample. 5. ** Multiplication Cultivation (Enrichment Cultivation)** - Take 10ml of the supernate, add 90ml of the mineral salt medium (121°C for 20min) and different concentration of the target pesticide contamination, and cultivate it in a shaking table at 30°C and 130r·min - 1. Under the same conditions, they would transfer the target microorganisms regularly to increase the number of target microorganisms. 6. ** Cultivation Separation ** - The microorganisms can be separated and purified by a diluted spread plate method, a diluted mixed plate method, or a plate streaking separation method, and the operation can be repeated until pure strains are obtained. 7. ** Selection ** - Dilute and spread on the solid medium of the organic salt, and cultivate in the incubator at 30°C for 2 - 3 days. According to the difference of the bacteria community, pick the single colony growing on the plate and inoculate it into the medium of the organic salt. Investigate the organic matter degrading effect, and select the strain with the ability to degrade the organic matter for further separation and purification, and finally obtain the high-efficiency functional strain. 8. ** Effect Test ** - After 7 days (with a deviation of 3 days allowed), samples will be taken to test the effect of the target microorganisms. If there is a repair effect, the experimental group with the best repair effect will be selected as the screening bacteria solution to complete the first round of screening of microorganisms. If there is no repair effect, samples will be taken again after 7 days (with a deviation of 3 days allowed). Generally, if there is still no repair effect after 30 days, soil samples need to be collected again. 9. ** Safety evaluation ** - This was an indispensable part of the screening process to ensure the safety of the screened functional microorganisms in application. ###2. Characteristic Evaluation Method 1. ** Evaluation of Function ** - Different functional microorganisms had different functional characteristics. For example, B. subtils could activate the soil to dissolve phosphorus and potassium, improve the soil, promote the root of crops, improve the absorption and utilization of nutrients, and enhance the immunity and disease resistance of crops; B. jelly-like had strong resistance to stress, strong environmental adaptability, efficient phosphorus dissolving function, and could improve soil hardening; B. licheniformis had the functions of dissolving phosphorus and potassium, secreting functional zymes, and producing active substances against pathogenic bacteria. The characteristics of the microorganisms were evaluated by testing whether they had these indicators related to their functions. - For example, the characteristics of T. harziana could be evaluated by its ability to control various soil-borne diseases such as phytophthora, sheath eyespot, and damping-off, as well as its ability to secrete gibberellins and other substances that promoted crop growth; Paecilomycopsis lilacinus could be evaluated by its functions of controlling plant root-knot nematodes, promoting plant growth, secreting various functional membranes, and degrading residual pesticide. 2. ** Evaluation of environmental adaptability ** - Observe the growth and reproduction of microorganisms under different environmental conditions, such as the performance of microorganisms when factors such as temperature, pH value, and nutrient concentration change. For example, the ability of Pseudomonads to rapidly grow and reproduce under low temperature conditions reflected its adaptability to low temperature environments. This was also an important aspect of evaluating its characteristics. 3. ** Growth and reproduction characteristics evaluation ** - It considered factors such as the reproduction speed and growth cycle of microorganisms. For example, the rapid reproduction rate of B. megatherum was an important factor to consider when evaluating whether it was a high-efficiency functional microorganisms. At the same time, the growth cycle would also affect the effect in practical applications. For example, in an application scenario that required a rapid effect, microorganisms with a short growth cycle might have an advantage. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Microorganisms are non-cellular microorganisms

Microorganisms that are non-cellular include viruses, viruses, and prions. Viruses were composed of a long chain of DNA and a protein shell. Nucleic acid was just one of the types of DNA or R A. It was parasitic on animal cells or plant cells, and its replication, replication, and translation were all completed in the host cells. Phages were viruses that were parasitic on bacteria, and their forms were tadpole-shaped, microsphere-shaped, and rod-shaped. Prions were actually infectious protein, and they were the pathogen of animal and human infectious cavernous brain diseases. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
