Clostridium ljungdahlii sp. nov. strain ATCC 49587T (T = type strain) was isolated from chicken yard waste for its ability to produce ethanol from synthesis gas. This gram-positive, motile, sporeforming rod's metabolism was primarily acetogenic. C. ljungdahlii grew with carbon monoxide, hydrogen and carbon dioxide, ethanol, pyruvate, arabinose, xylose, fructose, or glucose. Methanol, ferulic acid, lactate, galactose, and mannose did not support growth. The G+C content was 22 to 23 mol%. C. ljungdahlii is the first acetogen in clostridial 23S rRNA homology group I.
新种Ljungdahlii梭菌菌株ATCC 49587T（T =模式菌株）从鸡舍废弃物中分离出来，因其具有从合成气生产乙醇的能力。这种革兰氏阳性、具运动性、产芽孢的杆菌主要进行产乙酸代谢。Ljungdahlii梭菌能利用一氧化碳、氢气、二氧化碳、乙醇、丙酮酸、阿拉伯糖、木糖、果糖或葡萄糖生长。甲醇、阿魏酸、乳酸、半乳糖和甘露糖不能支持其生长。G+C含量为22至23摩尔%。Ljungdahlii梭菌是梭菌属23S rRNA同源群I中的首个产乙酸菌。
