Production of volatile organic compounds by mycobacteria.

abstract：:Ruminococcus albus is a Gram-positive bacterium that degrades plant cell walls in the rumen of herbivores. It was described to synthesize two major glycoside-hydrolases (Cel9B and Cel48A), which are exported and anchored at the cell surface. In bacteria, proteins destined to cross the cytoplasmic membrane are synthesi...
