title: [Elaboration of the method of "quiescent cells" for the study of heliomycin-synthesizing system of Streptomyces olivocinereus].
abstract: A resting cell procedure was developed for S. olivocinereus. Washed mycelium of S. olivocinereus produced heliomycin for a short incubation period of 1.5 hours in a nitrogen-free medium containing a buffer solution, salts, a source of carbon and an inhibitor of protein synthesis. With the developed procedure production of heliomycin in the system of resting cells was investigated. For this purpose mycelium collected during various phases of S. olivocinereus development in batch cultures was used. It was found that in the batch cultures the rate of heliomycin production by the 24th hour of the development was comparable with that of the antibiotic accumulation in the resting cell system. After that period it markedly decreased by the 48th hour. This deviation in the dynamics of heliomycin production in batch cultures and the resting cell system can serve as a basis for further studies on heliomycin biosynthesis control by the carbon source.
