Short communication: Benzene metabolism via the intradiol cleavage in a Rhodococcus sp.

Benzene was metabolized by Rhodococcus sp. 33 through the intradiol cleavage (ortho-) pathway producing cis-benzene glycol, catechol and cis, cis-muconic acid as the intermediates. This is the first elucidation of the pathway by which benzene is degraded by a gram-positive organism. The enzyme assays have also suggested that Rhodococcus 33 does not have a fully functional tricarboxylic acid cycle but may have an operational glyoxylate bypass.
