Methanogenic toluene metabolism: community structure and intermediates.

abstract：:Among human faecal bacteria, many members of the Clostridium leptum subgroup are fibrolytic and butyrate producing microorganisms thereby contributing to processes important to colonic health. Yet this phylogenetic subgroup remains poorly described to date. To improve detection and description of members of the C. lep...
