Is interspecies hydrogen transfer needed for toluene degradation under sulfate-reducing conditions?

Anaerobic degradation of toluene and xylene by aquifer microorganisms under sulfate-reducing conditions.

Toluene and the three isomers of xylene were completely mineralized to CO2 and biomass by aquifer-derived microorganisms under strictly anaerobic conditions. The source of the inoculum was gasoline-contaminated sediment from Seal Beach, Calif. Evidence confirming that sulfate was the terminal electron acceptor is presented. Benzene and ethylbenzene were not degraded under the experimental condi...

Complete oxidation of toluene under strictly anoxic conditions by a new sulfate-reducing bacterium.

A toluene-degrading sulfate-reducing bacterium, strain Tol2, was isolated from marine sediment under strictly anoxic conditions. Toluene was toxic if applied directly to the medium at concentrations higher than 0.5 mM. To provide toluene continuously at a nontoxic concentration, it was supplied in an inert hydrophobic carrier phase. The isolate had oval, sometimes motile cells (1.2 to 1.4 by 1....

Community dynamics within a bacterial consortium during growth on toluene under sulfate-reducing conditions.

A sulfate-reducing bacterial consortium was enriched from an anoxic aquifer contaminated with BTEX compounds, using toluene as a growth substrate. Total cell counts, protein contents and sulfide production were determined to follow growth at the in situ temperature (14 degrees C) and at 25 degrees C, respectively. Community members were identified by 16S rRNA gene cloning and sequencing. Phylog...

Summary Report on the Aerobic Degradation of Diesel Fuel and the Degradation of Toluene Under Aerobic, Denitrifying and Sulfate Reducing Conditions

Anaerobic Degradation of Hexadecan-2-one by a Microbial Enrichment Culture under Sulfate-Reducing Conditions.

A microbial enrichment culture from marine sediment was able to grow on hexadecan-2-one as the sole source of carbon and energy under sulfate-reducing conditions. Oxidation of the ketone involved carboxylation reactions and was coupled to sulfide production. This enrichment culture also grew on 6,10,14-trimethylpentadecan-2-one.
