摘　　要：单细胞油脂(single cell oil,SCO)是指单细胞产油微生物在菌体内大量积累的油脂。丝孢酵母是一种高产油脂的单细胞微生物。本文首先总结了丝孢酵母属常见的产油菌种及其脂肪酸组成,进而详细介绍了碳源、氮源、C/N比、无机盐等培养基成分和接种量、pH值、温度、培养时间等培养条件对其油脂生产的影响,并且全面归纳了丝孢酵母对木质纤维素水解物、工农业废弃物、淀粉类原料等廉价原料的利用,以及丝孢酵母SCO的应用。本文希望为丝孢酵母在SCO开发及利用领域的研究提供参考依据。Single cell oil(SCO)refers to a large amount of oil accumulated in the cell by single-cell oil-producing microorganisms.The strain Trichosporon sp.is known for producing high-yield SCO.This article first summarizes the common oil-producing strains and their fatty acid composition of Trichosporon sp.and then provides a detailed introduction to the effects of medium components such as carbon source,nitrogen source,C/N ratio,inorganic salt and cultivation conditions such as inoculation amount,pH,temperature and cultivation time on their oil production.It also comprehensively summarizes the use of cheap raw materials such as lignocellulosic hydrolysates,industrial and agricultural wastes,and starch raw materials by Trichosporon sp.,as well as the use of Trichosporon sp.SCO.This article aims to provide a reference base for Trichosporon sp.research in the field of SCO development and utilization.
