[Synthesis of biologically active lipids by fungus Mucor lusitanicus 306D grown on media with various composition].
Growth and lipogenesis of fungus Mucor lusitanicus 306 D producing gamma-linolenic acid was studied under various regimes of nitrogen and carbon nutrition. Media containing food industry wastes such as maize extract, molasses, and protein hydrolysate were used. Content of gamma-linolenic acid was higher when using carbohydrates such as glucose and molasses as carbon sources and urea as a nitrogen source. At high glucose concentration (100 g/l), fed batch cultivation provided high content of gamma-linolenic acid in lipids (1 g/l). After extraction of lipids, fungus biomass contained 42% proteins with all essential amino acids. Defatted biomass was shown to be effectively assimilated by minks.
