Biosynthesis of isochorismate in Klebsiella pneumoniae: origin of O-2.

abstract：:Bacterial strains and consortia of bacteria have been isolated for their ability to degrade, under anaerobic conditions, homocyclic monoaromatic compounds, such as phenolic compounds, methylbenzenes, and aminobenzenes. As opposed to aerobic conditions where these compounds are degraded via dihydroxyl intermediates int...
