摘要:同型产乙酸菌（homoacetogen）是一类既能利用多种有机底物异养生长，又能利用CO2/H2或者CO自养生存的厌氧微生物类群.其对各类生态环境适应能力强，可以通过厌氧乙酰辅酶A途径将不同底物转化为乙酸、乙醇等有机物.随着化石能源的枯竭与对同型产乙酸作用理解的加深，同型产乙酸菌逐步应用于有机物或者合成气厌氧发酵、环烃类有机污染物降解等环境生物技术中，成为近年来的研究热点.选择了一些研究较为广泛的同型产乙酸菌类型，介绍了相关生理生态特性，以及近年来针对同型产乙酸菌的环境应用研究进展.



Abstract:Homoacetogen is a kind of anaerobic microbial group which can utilize a variety of organic substrates and gas substrates(such as CO2,H2 and CO ) to form acetate, ethanol and other chemicals through acetyl -CoA pathway. They can survive in almost all kinds of ecological environment.With the depletion of fossil energy and the better understanding of homoacetogenic, it becomes more popular to apply homoacetogen into organic matter fermentation, syngas fermentation, and degradation of organic pollutants with nitrocellulose .Certain species of homoacetogen and their physiological and ecological characteristics are summarized in this paper. And the applications and research progress about homoacetogen in environmental biotechnology are also discussed thereafter.
