非粮生物质制备生物基丁二酸的研究进展

Progress in Microbial Production of Succinic Acid Using Non-food Biomass Feedstock

丁二酸(Succinic acid)是重要的碳四平台化合物,拥有巨大的潜在市场需求量。随着能源危机和粮食安全问题的日益严重,利用非粮生物质原料提高生物基丁二酸的竞争力成为研究的热点。文中从生产菌种的选育、非粮生物质原料的利用与产物提取3个方面对国内外相关研究进展进行综述,最后探讨该领域中所面临的问题与研究方向,并展望其发展前景。

Succinic acid is an important C4-platform chemical,which has huge market potential in applications.Diminishing petroleum reserves and increasing concerns on food security have resulted in worldwide interests in the study of bio-succinic acid production using non-food biomass feedstock.This article reviewed recent advances in the production of succinic acid by microbial fermentation,including discovery and screening of the succinic-acid-producing microbes,utilization of non-food biomass feedstock,and product recovery technology.Finally,we discussed the limitation of this progress and proposed the future research needs for succinic acid production using non-food biomass feedstock.
