【摘要】 从新西兰Ｒｏｔｏｒｕａ热温泉中分离出一株厌氧、极端嗜热的纤维素分解细菌。该菌株革兰氏染色阴性。不运动。不形成芽抱。细胞单个、成对或成链，呈直杆状，宽１．０—１．２μｍ，长３．０—７．０μｍ，在纤维素琼脂滚管上７０℃培养４天以后的菌落形态呈不规则状，不透明，产生淡黄色色素。发酵纤维素、一纤维二糖、葡萄糖产生氢、二氧化碳、乙醇、乙酸、微量乳酸。更多还原

【Abstract】 n extremely thermophilic anaerobic cellulolytic bacteria was isolated from hot spring of New Zealand Rotorua. The strain is gramreaction-negative. nonmotility, nonsporeformer. The cell are single. pair or chain. Single cells are rods. 1 .0μm to 1 .2 μm in width and 3.0μm to 7.0μm in length. The colonies in cellulose-agar roll tube are irreglar. nutranslucent, light yellow pigment at 70℃ after incubating 4 days. The productions of fermentation are hydrogen. carbon dioxide. ethanol. acetic acid and trace amount lactic acid from cellulose. cellobiose. glucose.更多还原
