[UV-sensitive mutants of Streptomyces olivaceus VKX].

14 UV-sensitive (uvs) mutants of S. olivaceus VKX isolated by replica-plating technique among 45780 survivors after the induction of mutations nitrosoguanidine or UV (about 0.03%). The sensitivity of uvs-mutants to UV-irradiation was 5-10 times higher than in the initial strains and in 4 uvs-mutants it was 100 and more times higher. One of the mutants was supersensitive to UV radiation.
