Anaerobic Degradation of Benzene in Diverse Anoxic Environments
Benzene has often been observed to be resistant to microbial degradation under anoxic conditions. A number of recent studies, however, have demonstrated that anaerobic benzene utilization can occur.Expand
Metagenomic analysis and metabolite profiling of deep–sea sediments from the Gulf of Mexico following the Deepwater Horizon oil spill
The hypothesis that increased hydrocarbon exposure results in an altered sediment microbial community structure that reflects the prospects for oil biodegradation under the prevailing conditions is examined and increased exposure to hydrocarbons enriches Deltaproteobacteria, which are known to be capable of anaerobic hydrocarbon metabolism.

In-situ evidence for uranium immobilization and remobilization.
Findings indicate that in-situ subsurface U(VI) immobilization can be expected to take place under anaerobic conditions, but the permanence of the approach can be impaired by disimilatory nitrate reduction intermediates that can mobilize previously reduced uranium. Expand
Anaerobic biodegradation of gasoline oxygenates: extrapolation of information to multiple sites and redox conditions.
The ether oxygenates were generally not degraded when incubated with various inocula, regardless of the electron acceptor status, and the partial transformation of methyl tert-butyl ether to tert- butanol after a 152-day acclimation period in a single replicate from a river sediment chronically contaminated with fuel suggested that the latter transformation was biologically catalyzed.

Diversity of benzyl- and alkylsuccinate synthase genes in hydrocarbon-impacted environments and enrichment cultures.
Data confirm that the assA gene is a useful biomarker for anaerobic alkane metabolism and expand the range of alkane-degrading conditions for which relevant gene sequences are available and indicate that considerable diversity of assA genes can be found in hydrocarbon-impacted environments. Expand
Desulfomonile tiedjei gen. nov. and sp. nov., a novel anaerobic, dehalogenating, sulfate-reducing bacterium
16S rRNA sequence analysis indicates the organism is a new genus of sulfate-reducing bacteria in the delta subdivision of the class Proteobacteria, and it is proposed that the strain be named Desulfomonile tiedjei. Expand
Pore‐size constraints on the activity and survival of subsurface bacteria in a late cretaceous shale‐sandstone sequence, northwestern New Mexico
To investigate the distribution of microbial biomass and activities to gain insights into the physical controls on microbial activity and potential long‐term survival in the subsurface, 24 shale andExpand
Detection of Phenol and Benzoate as Intermediates of Anaerobic Benzene Biodegradation under Different Terminal Electron-Accepting Conditions
A sulfate-reducing bacterial enrichment that anaerobically metabolized benzene was obtained from a petroleum-contaminated aquifer. During biodegradation, we observed the transient accumulation ofExpand
Biodegradation of low-molecular-weight alkanes under mesophilic, sulfate-reducing conditions: metabolic intermediates and community patterns.
The potential for anaerobic short-chain n-alkane metabolism for the first time in a terrestrial environment is documents, evidence for a fumarate addition mechanism for n-propane activation under these conditions is provided, and microbial community members present in such enrichments are revealed.

Influence of surfactants on microbial degradation of organic compounds
Abstract Surfactants have the ability to increase aqueous concentrations of poorly soluble compounds and interfacial areas between immiscible fluids, thus potentially improving the accessibility ofExpand
