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 ofClostridium glycolicum and KHb asBacteroides xylanolyticus . KHb fermented xylan and other saccharides that KHa could not utilize and formed products (e.g., ethanol and H2 ) that supported the acetogenic growth of KHa.
