Five growth variables (temperature, pH, carbon source, nitrogen source, and vegetable oils) were studied. Liquid media containing 2% vegetable oil (palm oil, canola oil, soybean oil, sesame oil, or sunflower oil) or 2% carbohydrate (fructose, galactose, glycerol, glucose, lactose, maltose, sucrose, sorbitol or xylose) and 1% yeast extract as a nitrogen source were used. The greatest biomass production was observed with M3 and M4 strains in palm oil (91.5 g l -1) and sunflower oil (68.3 g l -1) media, respectively. Strain M4 produced greater quantities of polyunsaturated acids in medium containing glucose. The GLA production in the M4 biomass was 1,132.2 mg l -1 in glucose medium. Plant oils were inhibitors of fatty acid production by these strains. © 2007 Academic Journals.1840-1847engγ-linolenic acidFatty acid productionMucor hiemalisPolyunsaturated acidscanola oilcarbohydratecarbonfatty acidfructosegalactosegamma linolenic acidglucoseglycerollactosemaltosenatural productnitrogenpalm oilpolyunsaturated fatty acidsesame seed oilsorbitolsoybean oilsucrosesunflower oilunclassified drugvegetable oilxylosebiomassBrazilfatty acid synthesisfungal strainfungus growthfungus isolationMucormucor hiemalisnonhumanpHsoil microflorastrain differencetemperatureBrassica napus var. napusGlycine maxHelianthusSesamum indicumArtigo10.4314%2Fajb.v6i15.57807WOS:000248685500021Acesso aberto2-s2.0-345480945562-s2.0-34548094556.pdf
