Notes:
Conidia of glucose oxidase active Aspergillus niger G 13 strain were subjected to the fourth-stage mutagenization using different combinations of mutagens in each stage (stage I - UV radiation + nitrosomethylurea, stage II - UV radiation + ethyleneimine, Stage III - acryflavine, stage IV - UV radiation + N-methyl-N′-nitrosoguanidine). In all, 400 strains which showed higher glucose oxidase activity with our own diffusion data method (were isolated out of 5208 colonies after mutagenization). Nine most active mutants were tested in the submerged culture determining the activity of glucose oxidase in the post-culture liquid which increased from 10.7 to nearly 30%.
