产油微生物利用餐厨垃圾生产油脂的研究进展

餐厨垃圾中含有丰富的营养物质,经生物转化过程可以合成对人类有用的化学品。某些产油微生物可以处理餐厨垃圾生产油脂,同时合成高附加值代谢产物如多不饱和脂肪酸、角鲨烯和类胡萝卜素等。这不仅能够降低生产成本,而且提高了产物的经济价值,具有极大的工业化应用潜力。文中主要概括了目前餐厨垃圾的处理研究现状,综述了产油微生物发酵餐厨垃圾生产油脂的研究进展,并结合笔者的工作对未来该领域的发展进行了总结与展望,以期为今后的相关研究提供有益借鉴。

Lipid production by oleaginous microorganisms using food wastes: a review

Food wastes are rich in nutrients and can be used for producing useful chemicals through biotransformation. Some oleaginous microorganisms can use food wastes to produce lipids and high value-added metabolites such as polyunsaturated fatty acids, squalene, and carotenoids. This not only reduces the production cost, but also improves the economic value of the products, thus has large potential for commercial production. This review summarized the advances in food waste treatment, with a focus on the lipid production by oleaginous microorganisms using food wastes. Moreover, challenges and future directions were prospected with the aim to provide a useful reference for related researchers.
