Studies on estuarine yeasts. 2: Laboratory experiments on growth and production

E. DaCosta, J. DeSouza


Five hydrocarbon degrading isolates: Candida parapsilosis (three isolates), C. tropicalis (one isolate), Saccharomyces cerevisiae (one isolate) were studied for their growth, biomass, production and fermentation of diesel oil. Growth in Wickerham's medium and mineral base medium with diesel oil as the sole source of carbon were compared. The protein content in these yeasts ranged from 32.28-58.73% and the biomass production was optimum on the 20th day. The products of fermentation showed the presence of two fatty acids by TLC with Rf values 0.13 and 0.29 respectively
