There are no particular problems in large organisms, and for microorganisms, their traits are often difficult to distinguish with the naked eye. Therefore, a simple and easy method commonly used is the plate culture method, that is, from the plate culture colonies, the obtained pure strains are subjected to identification and screening one by one. However, in the antagonistic system, a selection medium containing a drug and a phage is required for screening. Sometimes the different traits that are chosen according to the needs are often more complicated in operation than the above. The photolithographic method has been applied as a subtle method. Through the statistical analysis of this method and its results, it has been determined that this resistance to the resistance of the resistant substance and the need for the condition of the gene expression are incompatible with the normal living environment. The general use of mutations and selection of proliferation is explained, and it is considered that the mutation is completely unrelated to the adaptation conditions given.
