title: Reductive desulfurization of dibenzyldisulfide.
abstract: Dibenzyldisulfide was reductively degraded by a methanogenic mixed culture derived from a sewage digestor. Toluene was produced with benzyl mercaptan as an intermediate in sulfur-limited medium. Toluene production was strictly associated with biological activity; however, the reducing agent for the culture medium, Ti(III), was partially responsible for production of benzyl mercaptan. Sulfide was not detected. Additions of sodium sulfide did not inhibit toluene production. Additions of 2-bromoethane sulfonic acid prevented methanogenesis but did not adversely affect toluene yields.
