The effect of various culture conditions on growth, lipid production and fatty acid composition in Mucor rouxii and Mucor sp.1b were studied. Total lipid production was higher in media containing potassium nitrate for both the cultures (30%) and cultures grown on plant seed oil produced more than 44% lipid. Among the carbon sources tested, gamma-linolenic acid (GLA) production was maximal in cultures grown on glucose. The major fatty acids produced by these two cultures were palmitic, stearic and oleic acids. Levels of GLA in M. rouxii and M. sp.1b was in the range of 3-17% under different culture conditions. Lactose was a poor promoter for biomass and lipid production in both cultures. No GLA was found in fungal cultures grown on sesame oil. The optimal conditions for the production of GLA was standardised in these cultures. (C) 2002 Elsevier Science Ltd. All rights reserved.
