Effect of nutritional factors on lipase biosynthesis by Aspergillus niger

Lipase biosynthesis occurred in medium without lipids, but for improved production on inducer was needed. The source and concentration of an inducer had no significant effect. Starch as an additional carbon source stimulated lipase biosynthesis when used in small amounts. Addition of NE4NO3 as a nit...

Zusammenfassung:	Lipase biosynthesis occurred in medium without lipids, but for improved production on inducer was needed. The source and concentration of an inducer had no significant effect. Starch as an additional carbon source stimulated lipase biosynthesis when used in small amounts. Addition of NE4NO3 as a nitrogen source, KH2PO4 as a phosphate source as well as Mg ions to the medium with initial pH 5.0 gave the best yield.
