摘　　要：从降解有机物产生甲烷的富集培养物中分离到一株利用巴豆酸的严格厌氧革兰氏阴性杆菌.此菌利用氢和二氧化碳或甲酸合成乙酸,发酵巴豆酸产生丁酸和乙酸,发酵葡萄糖、果糖、麦芽糖和半乳糖产生乙酸、乙醇和氢或甲酸,不利用延胡索酸、酒石酸和柠檬酸生长.该菌不产生芽孢,不还原硫酸盐,触酶反应阴性,DNA的G+C含量为30.7±1mol%,是泥杆菌属中的一个新种,定名为嗜氢泥杆菌(Ilyobacter hydrogenotrophicus nov.sp.).From a methanogenic organic-degrading enrichment, a new strictly anaerobic Gram-negtive non-sporoforming bacterium, strain 116 was isolated with crotonate as substrat. Hydrogen and carbon dioxide or formate were utilized to synthese acetate and crotonate was fermented to acetate and butyrate. Glucose, fructose, maltose and galactose were fermented to acetate,ethanol and hydrogen or formate. Neither fumarate, tartrate nor citrite was utilized. No sulfate was reduced. The G+C mmol/L was 30. 7±1%. The strain is described as a new species,Ilyobacter hydrogenotrophicus sp. nov. and strain 116(AS 1. 1788) is designated as the type strain.
