EFFECT OF CARBON AND NITROGEN-SOURCES ON GROWTH, LIPID PRODUCTION ANDFATTY-ACID COMPOSITION OF MUCOR-MUCEDO F-1384

The influence of twelve individual carbon sources and six nitrogen com pounds on growth, lipid content and fatty acid composition of Mucor mu cedo F-1384 was investigated. The best growth was observed on maltose and the yield of lipid production decreased in the order: maltose > st arch hydrolysate > glucose > glycerol > xylose > ethanol > starch > su crose > fructose > lactose > methanol > galactose. It seems that subst rates containing organic nitrogen are more beneficial for growth compa red with inorganic N-sources. Fatty acid analysis showed preferential accumulation of oleic and linoleic acid despite the N and C sources us ed. On the other hand the nature of the substrates affected in particu lar the content of gamma-linolenic acid.
