Bioenergetic parameters of two isogenic strains of Acremonium chrysogenum markedly differing in their capacity for biosynthesis of cephalosporin C were studied. It was shown that in the high productive strain the system of oxidative phosphorylation p

Electron microscopy of the ultrastructure of the Aspergillus niger cells exposed to cyclosporine in acute experiments revealed changes in the mycelium morphology, hyphae growth and cell structure in the organism sensitive to cyclosporine. The analysi

Sensitivity of the representatives of Aspergillus and Piricularia to various concentrations of cyclosporine (in the submerged culture) was studied for choosing the test object for the subcellular investigation of the mechanism of the cyclosporine ant

An analogy was observed between the mechanisms of action of phytohormones on plant cells and cells of the fungus producing cyclosporine. Fusicoccin and cytokinin were shown to have a high stimulating action on the biosynthesis of cyclosporine. The st

The activities of the key glycolytic enzymes i.e. hexokinase, phosphofructokinase, pyruvate kinase and lactate dehydrogenase were detected and investigated in 3 strains of Streptomyces rimosus differing in the level of the oxytetracycline production.

The culture of Xanthomonas rubrilineans was able to synthesize a number of intracellular aminopeptidases. To study localization of the enzymes in the cells, a protoplasting procedure was developed providing the yield of 99.7 per cent. The following s

Enzymes of various glycolysis stages, i.e. hexokinase, phosphofructokinase, pyruvate kinase and lactate dehydrogenase, were detected in cyclosporine-producing organisms belonging to Tolypocladium. The initial activity of the enzymes in the highly act

A bireplicone plasmid pSU901,4.6 kb in length, was constructed on the basis of plasmid pUC19 and the pstIB fragment, 1.9 kb in length, from mitochondrial DNA of A. chrysogenum. Based on the hybrid plasmid pSU901 and kanamycin resistance determinant,

The contents of high-energy phosphorous compounds, i.e. three fractions of polyphosphates, pyrophosphate, and ATP were determined in isogenic strains of Tolypocladium sp. differing in cyclosporine production levels. The content of polyphosphates was

An attempt was made to show a correlation between definite bioenergetic parameters of the cells of the cyclosporine-producing culture and biosynthesis of cyclosporine. It was found that the three strains producing cyclosporine used in the study had a
