[Utilization of the mix of growth and nongrowth substrates by microorganisms].
Author's experimental data and those from literature, concerning the utilization of growth and nongrowth substrates by microorganisms, are presented in the review. The notions "growth" and "nongrowth" substrate as well as the types of transformation of mixed substrates (mixotrophy, diauxia, nongrowth oxidation, cometabolism, syntabolism) have been considered. Main propositions of the conception of auxiliary substrate and the essence of energetic classification of substrates have been presented. Data from literature concerning the effect of cultivation conditions (concentration of substrates, their ratio, cultivation method, dissolution rate under continuous cultivation, etc.) on the character of substrate mixed use, as well as the use of mixed substrates aimed at the intensification of microorganism growth. Data are presented on the intensification of metabolites synthesis (e. g. microbial exopolysaccharide etapolan) on the mixture of energetically non-equivalent growth substrates.
