The dependence of the biosynthesis of extracellular glucose oxidase by Penicillium varians from carbon-containing nutrient medium components

Abstract

Influence of carbon-containing compounds on production of extracellular glucose oxidase by Pénicillium varians BIM F563 D was studied. It was found that glucose (7%) and sucrose (6%) proved the optimal carbon sources for enzyme biosynthesis. Extra supply of pectin, xylan, gelatin (0.05%) and ethanol (1%) or butanol (0.5%) results in increased level of enzyme generation - by 44, 34, 32, 35, 50 %, respectively. The revealed promoters of glucose oxidase synthesis by Pénicillium varians BIM F563 D may be engaged in elaboration of enzyme production technology.
