Clostridium利用合成气发酵生产生物燃料和化学品的研究进展
Progress in production of biofuels and chemicals from syngas fermentation by Clostridium
综述了利用自产乙醇梭菌(Clostridium autoethanogenum)进行合成气发酵生产生物燃料和化学品的最新进展。自产乙醇梭菌是一种严格厌氧的革兰氏阳性菌通过Wood-Ljungdahl途径进行代谢,主要生成乙醇和乙酸。重点介绍了合成气发酵工艺的多方面优化,包括培养基组分优化、工艺参数调整、微生物光电催化系统构建、微生物共培养系统等方面,这些技术进一步推动了该领域的发展。最后提出了当前研究存在的不足,并对未来的研究方向做出了展望,旨在为微生物合成气发酵在生物燃料和化学品生产领域提供参考。
This paper reviews the latest advances in using Clostridium autoethanogenum to perform syngas fermentation for the production of biofuels and chemicals.Clostridium autoethanogenum is a strictly anaerobic Gram-positive bacterium metabolized via the Wood-Ljungdahl pathway to produce ethanol and acetic acid.This paper highlights the multifaceted optimization of the syngas fermentation process,including the optimization of medium components,the adjustment of process parameters,the construction of microbial photoelectrocatalytic system,microbial co-cultivation system,and the application of genetic engineering,which have further advanced the development of the field.Finally,the shortcomings of the current research are presented,and the future research directions are prospected,aiming to provide a reference for microbial syngas fermentation in the field of biofuels and chemicals production.
