BACTERIAL OXIDATION OF BENZENE

Abstract
Two organisms, a strain of a Pseudomonas species and one of a Mycobacterium species, capable of oxidizing benzene as a sole carbon source, were isolated from soil by an enrichment culture technique. Both organisms oxidized benzene manometrically with sufficient oxygen uptake to account for oxidation to carbon dioxide and water. A metabolic pathway for the breakdown of benzene via 3,5-cyclohexadiene-l,2-diol and catechol is proposed. Phenol and o-benzoquinone are not probable intermediates in the oxidation of benzene by these organisms.
