With the continuous development of social life, people's demand for oil and fat chemicals has increased dramatically, but also shows a variety of product demand. Oils chemicals are widely used in cosmetics, food, pharmaceuticals, lubricants, detergents, etc. They can also be used to track human fat metabolism pathways and study the metabolism of glycerides in patients with fat metabolism diseases. Fully develop and utilize microbial grease and broaden its application range will significantly improve its own value and reduce the production cost of microbial grease. At present, when using oil-producing yeast to ferment and produce, the fatty acids accumulated by most microorganisms are mainly oleic acid, palmitic acid, and stearic acid. In addition, a small amount of linoleic acid, myristic acid, linolenic acid, and icosicarbonic acid., Dococarbonic and 24-carbonic acid, 11-carbonate triglyceride, etc. The use of oil production to produce such fatty acids has a wide range of uses, but it limits its further development potential. Therefore, it is of great significance to broaden the map of oil-producing yeast oil products and improve the economic value of microbial oil.
