微生物菌群发酵生产化学品的研究进展

Progress in chemicals production by microbial consortia

廉价生物质资源的利用是工业生物技术领域研究的热点,复杂的成分和较多的杂质使传统的单菌发酵方式难以应对,成为产业化的关键问题。文中从微生物菌群的工业应用、微生物菌群发酵与纯种发酵的比较、微生物细胞间的相互作用等方面综述了微生物菌群发酵技术的最新研究进展,并对微生物菌群的设计和应用进行了展望。微生物菌群发酵可以充分利用廉价生物质基质、生产多个产品或减少副产物的生成,在生物基化学品和燃料的生产中将是一种有前景的发酵技术。

Using cheap biomass resources is a hotspot of research on industrial biotechnology. It is difficult for traditional fermentations with single strain to treat so complex components and more impurities, which becomes the key problem in industrialization, tn this review, some existing industrial bioprocesses involving microbial consortia were described. Comparison of 1,3-propanediol production by microbial consortia and pure cultures were then introduced and the relationship between cells in microbial consortia were summarized. Finally, the perspective was also addressed to design and apply microbial consortia in the future.
