Spontaneous variability of glucose oxidase-producing fungus Penicillium adametzii LF F-2044

Abstract

The glucose oxidase-producing fungus Penicillium adametzii LF F-2044 was studied for natural variability. Four variants of the fungus differed in morphological characteristics and glucose oxidase synthesis. The synthesis of extracellular glucose oxidase and the productivity of morphological variants P. adametzii LF F-2044.1 and P. adametzii LF F-2044.2 were 127-146 and 95-159% higher, respectively, than the control. Highly active morphological variants of the fungus were chosen for further selection experiments.
