[Selection of the optimal conditions for the procurement and regeneration of protoplasts of the industrial strain of Streptomyces rimosus, the producer of oxytetracycline, and the effect of the protoplasting process on the antibiotic activity].

Optimal conditions for protoplasting of the Streptomyces rimosus industrial strain No. 1 producing oxytetracycline were developed. Observation of the early stages of the protoplast regeneration in microchambers showed that there were two regeneration types: normal and anomalous. The latter was likely defined by the glycine effect on cell wall synthesis. It… CONTINUE READING
