Abstract:
The ability of 311 actiomycete, belonging to 12 species to produce glucose oxidase was studied. It was found that 174 of them formed exoenzymes on solid medium and 133 in liquid medium. The composition of the nutrient medium has an essential effect on the amount of enzyme formed. Strains with considerably higher activity form a greater amount of exoenzymes on soya meal medium and on synthetic medium with KNO2. The highest activity of the culture liquid of some strains was observed between the 6th and 7th day of cultivation. During this phase of growth the highest productivity of the biomas was established.
