Background: Oil is an important fat source of all organisms. Yeast is a unicellular fungus, very much useful in various industries, especially used in food industry. Methods: In this work, various vegetable oils such as coconut oil, gingili oil, neem oil, Castrol oil and sunflower oil were used to test their influence on biomass production of yeast. First 10% of various oils are mixed with freshly prepared yeast broth medium, and then yeast were inoculated and incubated at 37oC.After 48 hours, biomass production was studied in all the treatment. Results: The maximum biomass production was observed in gingili oil, least production was observed in control treatment. Because distilled water was used as control and another least production was observed in Castrol oil, because it may due to its viscosity. Conclusion: If develop low cost culture medium for yeast biomass production. These results will be very much useful to yeast production industry.
