Energy parameters of the two strains of the inperfect fungus Fusidium coccineum with different levels of antibiotic production were studied comparatively. It was shown that the respiration activity of the both strains was almost completely suppressed by KCN+ salycyl hydroxomate. It provided a supposition that the respiration activity was almost selectively connected with the mitochondria. The analysis of the energy parameters and especially the efficiency of the substrate consumption indicated that the system of oxidative phospholiration was dominant in the energy supply in both the strains. The differences between the strains were observed in the growth rate and the level of KCN-stable respiration. A change in the respiration of the active strain to the alternative KCN-stable path was observed by the end of the 6-8 day fermentation process when significant amounts of fusidin accumulated in the fermentation broth. Correlation between the level of KCN-stability and the antibiotic production was found.

UI MeSH Term Description Entries
D010101 Oxygen Consumption The rate at which oxygen is used by a tissue; microliters of oxygen STPD used per milligram of tissue per hour; the rate at which oxygen enters the blood from alveolar gas, equal in the steady state to the consumption of oxygen by tissue metabolism throughout the body. (Stedman, 25th ed, p346) Consumption, Oxygen,Consumptions, Oxygen,Oxygen Consumptions
D003470 Culture Media Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN. Media, Culture
