Anaerobic benzene degradation in petroleum-contaminated aquifer sediments after inoculation with a benzene-oxidizing enrichment
Article Abstract:
Aquifer sediments taken from the sulfate-reducing zone of a jet fuel-contaminated aquifer were treated with benzene to further investigate the potential for anaerobic benzene degradation coupled to sulfate reduction in aquifers contaminated with petroleum. The findings indicate that the persistence of benzene under sulfate-reducing conditions in the contaminated aquifer was due to the absence of benzene-oxidizing sulfate reducers in the aquifer sediments and not to the failure of the reducers to grow and metabolize under freshwater conditions.

Inhibition of methane oxidation by Methylococcus capsulatus with hydrochlorofluorocarbons and fluorinated methanes
Article Abstract:
The inhibition of methane oxidation by methylococcus capsulates with hydrochlorofluorocarbons and fluorinated methanes was studied. The investigation utilized cell suspension of methylococcus capsulates exposed to hydrochlorofluorocarbon 21 and different fluorinated methanes. Results reveal that increased employment of the inhibitor methyl fluorides to quantify methane oxidation in soils and sediments inhibit methane oxidation by whole cells.

Microbial degradation of hydrochlorofluorocarbons (CHCl2F and CHCl2CF3) in soils and sediments
Article Abstract:
Experiments are performed to analyze the ability of microorganisms to degrade trace levels of hydrochlorofluorocarbons HCFC-21 and HCFC-123 in aerobic soils, freshwater and salt marsh sediments. Results suggest that significant variability exists among the microorganisms tested with regard to their ability to metabolize HCFC-123 and HCFC-21. The data also indicate that HCFC is more biodegradable by these bacteria than HCFC-123.
