title: [Effect of different nitrogen sources on the biosynthesis of lipase by Oospora lactis].
abstract: The effect of inorganic and organic nitrogen compounds on the synthesis of biomass and extracellular lipase by Oospora lactis was studied. Among the inorganic nitrogen sources ammonium sulphate and ammonium secondary phosphate and among the organic nitrogen sources yeast autolysate proved to be most beneficial for the lipase synthesis. Lipase activity and biomass accumulation in the medium containing yeast autolysate were greater than in the media containing the above ammonium salts. Lipase synthesis reached maximum in the nutrient medium containing yeast autolysate (0.7%) and ammonium sulphate (0.3%).
