同型乙酸菌研究进展及应用前景

Progress in Research and Application of Homoacetogen

同型乙酸菌是一类分布极广、形态差异极大的微生物类群.该类微生物利用厌氧乙酰辅酶A途径合成代谢中间体乙酰辅酶A,即可营自养生活亦可营异养生活;可利用多种物质作电子供体及电子受体,代谢能力强,底物范围广,能够生成多种代谢产物,如乙酸、乳酸、琥珀酸及甲酸;其独具特色的生理代谢特点,具有应用于工业生产的巨大潜力.本文就同型乙酸菌特有的代谢特点及应用前景作一综述.

Homocetogen distributes widely and is a phylogenetically diverse group of microorganisms. With robot metabolic capability, most bacteria of this group can utilize a variety of substrates as electrical supplier and receptor. Therefore, most of them can use very diverse substrates and form some commodity chemicals, such as acetate, lactose and succinate. These organisms use acetyl - CoA pathway for tacetyl - CoA synthesis as metabolic precursor, and grow autotrophically and heterotrophically. The unique physiological characters and great application potentiality of homoacetogen have attracted biologists＇ more and more attention. This paper presents a review on research and application of homoacetogen. Fig 2, Tab 1, Ref 18
