Lipid production by Candida Y-1

Ten oleaginous yeasts were isolated from sources like fruits, flowers, curd whey and soil samples. Lipid production varied from 24 to 71.2% of dry weight of cell biomass. Strain Y-1, which was isolated from curd whey, produced the highest amount of lipid. It was identified belonging to the genus Candida. The optimal cultural conditions for lipid production by Candida Y-1 were found to be glucose (5%) as carbon source, ammonium sulfate (1%) as nitrogen source, pH 4.5, and temperature 28 degrees C under shake-flask conditions (125 rpm).
