中文摘要:

      粗甘油是生物柴油生产中的一个主要副产物, 而通过微生物可将粗甘油转化为高附加值的1,3-丙二醇。1,3-丙二醇在食品、化工、医药、化妆品等很多领域具有非常广泛的应用。本文从1,3-丙二醇的粗甘油生物转化的迫切性、生产的菌种、合成的途径、合成的基因、发酵转化以及生产中的问题与策略等方面综述了微生物发酵粗甘油生成1,3-丙二醇的最新研究进展。

英文摘要:

      Crude glycerol is a major by-product in the production of biodiesel, and it can be transformed into high value-added 1,3-propanediol by microbial fermentation. 1,3-propanediol has a very wide range of ap-plication in food, chemical, pharmaceutical, cosmetics and many other fields. In this study, based on the microbial transformation of 1,3-propanediol from crude glycerol, the urgency, strains, synthetic pathway, genes, fermentaton and the problems and strategies were reviewed.
