What are the features of breeding work with microorganisms?

The selection of microorganisms has a number of specific features. Microorganisms, as a rule, have fewer genes than animals and plants; the mechanisms of regulation of gene activity are simpler. In addition, the breeder has an unlimited amount of material to work: billions of cells can be grown on nutrient media in a matter of days. Mutagenesis is widely used in the selection of microorganisms, and since most microorganisms are haploid, mutant forms can be detected already in the first generation. In addition, a combination of genes is used by conjugation – the exchange of genetic material between bacterial cells.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
