摘要:

随着生物柴油产业的发展,其主要副产物粗甘油的产量也逐年增加。大量粗甘油的产生不仅给环境造成了污染,也使精制甘油的市场价格大幅度下降。甘油是一种稳定的多功能化合物,可用作精细化工合成的基本原料。利用微生物转化甘油生产各种生物基化学品,因其具有绿色环保、可持续发展等特点,越来越受到人们的重视。本文简单介绍了甘油经微生物发酵的有氧代谢途径和厌氧代谢途径,重点分析了微生物发酵技术在粗甘油转化为1,3-丙二醇、生物乙醇、乳酸、1,3-二羟基丙酮的应用,旨在为平台化合物的工业化生产提供参考。

Abstract:

With the development of biodiesel industry, the yield of the main by-product crude glycerol, increased year by year. The production of a large amount of crude glycerol not only caused pollution to the environment, but also greatly reduced the market price of refined glycerol. Glycerol was a stable multifunctional compound, which could be used as the raw material for fine chemical synthesis. The conversion glycerol to all kinds of bio-based chemicals by microorganisms has attracted more and more attention because of its environmental protection, sustainable development and other characteristics. In this paper, the aerobic and anaerobic metabolic pathways of glycerol by microbial fermentation were briefly introduced, and the application of the conversion of crude glycerol to 1, 3-propanediol, bioethanol, lactic acid and 1, 3-dihydroxy ketone by microbial fermentation was emphatic analyzed, in order to provide references for the industrial production of platform compounds.

Key words: biodiesel, crud glycerol, microbial consortia, biorefinery, bio-based chemicals
