It is commonly known as edible oil and possesses a great impact on human day-to-day life. It is commonly known as edible oil and possesses a great impact on human day-to-day life. Animals living in water consume this oil and find it hard to digest and eventually or later it dies. The usage of microorganisms, especially yeast species are being employed for degrading the waste cooking oil. The organism Yarrowia lipolytica was isolated and waste oil sample collected was subjected to degradation with the culture. The samples were tested for turbidity, lipase enzyme production, and chemical oxygen demand. The quality of the wastewater after biodegradation can yield non-hazardous waste cooking oil. Keywords Biodegradation, Chemical oxygen demand, Lipase enzyme, Yarrowia lipolytica, Waste cooking oil.

Keywords Biodegradation, Chemical oxygen demand, Lipase enzyme, Yarrowia lipolytica, Waste cooking oil.
