[Cultivation of Endomyces magnusii yeasts under batch and continuous conditions at an acid pH].
The energy parameters of Endomyces magnusii cells and mitochondria were studied under the conditions of batch and continuous cultivation at different pH of the medium containing ethanol. The yeast was found to be capable of growth in the chemostat regime at D=0.2 h-1. Changes in the pH of the medium from 3.0 to 5.6 almost did not change the parameters characterizing oxidative phoshorylation of the mitochondria (the respiration chain contained three phosphorylation points). This correlated with the nearly identical biomass yield and economical coefficient. The content of RNA, DNA and protein remained unchanged at different pH values whereas the content of lipids increased at acid pH.
