The microorganism utilized sun flower oil, capric acid and oleic acid for growth, and biomass accumulation giving highest yield with oleic acid as substrate after 96 h of incubation reaching up to 2.1 g/L CDW, followed by the fatty acid groups capric acid with 0.87 g/L and sun flower oil 0.65 g/L, both after 96 h of cultivation. In contrast with the other fatty acids tested, caprylic acid and undecylenic acid were not a good substrate for microbial growth, and no growth was detected after 96 h of cultivation.
