Abstract: | Glutamate oxidase activity was studied in 1254 Streptomyces strains isolated from the zonal soils of various regions of Russia and other countries. Seven strains proved to be producers of extracellular L-glutamate oxidase. The most active producer strain was identified, and the conditions of enzyme biosynthesis were optimized. A multistep-mutagenesis and selection procedure allowed a genetically stable strain, Streptomyces sp. Z-11-6, to be obtained, whose glutamate oxidase activity was 40 times higher than that of the original natural isolate. |
