In complementation analysis of low active streptidine dependent strains of Act. streptomycini, 170 and 145 with mutants having different blocks in biosynthesis of streptomycin it was found that these strains were the donors of some thermostable substances and could reduce the biosynthesis of streptomycin in the mutants having impairements in biosynthesis of streptidine and streptobiosamine, as well as in a number of strains with unknown blocks. It is supposed that the substances produced by mutants 170 and 145 were intermediate products in streptomycin biosynthesis.
