| 摘 要： | 自然界中少量微生物在适宜条件下产生并贮存质量超过其细胞干重 2 0 %的油脂 ,具有这种表型的菌种称为产油微生物。产油微生物利用可再生资源 ,得到的微生物油脂与植物油脂具有相似的脂肪酸组成 ,有的还含有丰富的多不饱和脂肪酸 ,具有广阔开发应用前景。简要介绍了产油微生物的种类和代谢特点 ,较详细地阐述了微生物产油机制和代谢调控途径的最新研究进展 ,并对微生物油脂研究的未来发展方向提出了初步见解

| Abstract: | Oleaginous microorganisms are small portion of organisms that have ability to accumulate lipids over 20% of their biomass. These species can transform renewable material into microbial oil with similar fatty acid composition to that of plant-based oil. Some organisms may also produce glycerides with high content of poly-unsaturated fatty acids. Therefore, microbial lipids are considered as potential oil resource. Summarized here are some features of oleaginous species and recent developments on their biosynthetic machinery and metabolic regulation mechanism. |
