Isolate KH was obtained from Hawaiian forest soil and found to be composed of two functionally linked anaerobes, KHa and KHb. Gene analyses (16S rRNA, fhs, cooS) identified KHa as an acetogenic strain of Clostridium glycolicum and KHb as Bacteroides xylanolyticus. KHb fermented xylan and other saccharides that KHa could not utilize and formed products (e.g., ethanol and H(2)) that supported the acetogenic growth of KHa.
从夏威夷森林土壤中分离得到 KH,发现它由两种功能相关的厌氧菌 KH a 和 KH b 组成。基因分析(16S rRNA、fhs、cooS)鉴定 KH a 为产乙酸的糖酵解梭菌(Clostridium glycolicum),KH b 为木聚糖分解菌拟杆菌(Bacteroides xylanolyticus)。KH b 发酵木聚糖和 KH a 不能利用的其他糖,并形成产物(如乙醇和 H2),这些产物支持 KH a 的产乙酸生长。
