title: [Effect of heat shock on biosynthesis of antibiotics by three strains of Streptomyces].
abstract: Effects of heat shock on the biosynthesis of antibiotics, actinomycin C (in cultures of Streptomyces sp. 26-115 and S. chrysomallus 23209) and antibiotics of the nonactin group (in the culture of S. werraensis 1365) were studied. After heat shock, the formation of antibiotics of the nonactin group and actinomycin C were shown to increase by 30% and 27%, respectively, in comparison to control values. Thus, heat shock stimulates the biosynthesis of antibiotics in all three strains of streptomyces studied.
