The methods of industrial strains selection on the basis of some regulatory mechanisms are presented. The selection of the producing S. erythreus mutants exhibiting higher activity for transformation of erythromycin C to erythromycin A is one of the examples for the practical use of the presented method. Some new techniques including isotopic methods are presented.
