title: Methanogens and anaerobes in a colon segment isolated from the normal fecal stream.
abstract: Methanogens were in the isolated sigmoid colon but not in the colostomy bag of a woman with a left hemicolectomy with end colostomy and mucous fistula. The predominant methanogen was Methanobrevibacter smithii. An anaerobic bacterial community supported by nondietary substrates was present in the isolated sigmoid colon.
