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%).
研究了无机和有机氮化合物对乳酸卵孢霉合成生物量和胞外脂肪酶的影响。在无机氮源中，硫酸铵和磷酸二氢铵，在有机氮源中，酵母自溶物被证明对脂肪酶合成最有益。含有酵母自溶物的培养基中的脂肪酶活性和生物量积累大于含有上述铵盐的培养基。在含有酵母自溶物（0.7%）和硫酸铵（0.3%）的营养培养基中，脂肪酶合成达到最大值。
