title: [Sporogenesis, antibiotic biosynthesis and the systematic position of Fusidium coccineum].
abstract: Cytomorphological study of the wild and isogenic improved strains of F. coccineum revealed that with increasing of the antibiotic potency the character of the strain sporulation changed towards predominant formation of the spore "heads" which is characteristic of the sporogenesis of the genus Acremonium. These data allow one to revise the systematic position of the strains of F. coccineum and to classify them according to Gamsas belonging to Acremonium designated as Acremonium fusidioides. The criteria of the highly potent strains of this organisms are the following: formation of the spore "heads", changes in the event sequence during sporulation, decreasing of the spore index L/B with an increase in the strain potency. These criteria may be used in further improvement on the organism.
