Comparative bioremediation of soils contaminated with diesel oil by natural attenuation, biostimulation and bioaugmentation.
Natural attenuation was more effective than biostimulation (addition of nutrients), most notably in the Hong Kong soil, and bioaugmentation of the Long Beach soil showed the greatest degradation in the light and heavy fractions of TPH. Expand
Chromate reduction by chromium-resistant bacteria isolated from soils contaminated with dichromate.
The effects of some environmental factors such as pH, temperature, and time on Cr(VI) reduction and resistance are described and it is found that chromium-resistant bacteria can tolerate 2500 mg L(-1)Cr(VI), but most of the isolates tolerated and reduced Cr( VI) at concentrations lower than 1500 mg L (-1).

In vitro reduction of hexavalent chromium by a cell-free extract of Bacillus sp. ES 29 stimulated by Cu2+
This study characterizes the enzymatic reduction of Cr(VI) by Bacillus sp. Expand
Enrichment and isolation of endosulfan-degrading microorganisms.
The results of this study suggest that these novel strains are a valuable source of potent endosulfan-degrading enzymes for use in enzymatic bioremediation. Expand
Biodegradation kinetics of endosulfan by Fusarium ventricosum and a Pandoraea species.
The results of this study suggest that these novel strains may be used for the bioremediation of endosulfan-contaminated sites. Expand
Reduction of perchlorate and nitrate by salt tolerant bacteria.
It is demonstrated that both anions can be reduced in treatment of brines from ion exchange systems. Expand
Microbial consortium bioaugmentation of a polycyclic aromatic hydrocarbons contaminated soil.
Bacterial and fungal isolates from the consortium, when inoculated separately to the soil, were less effective in anthracene mineralization compared to the consortium and signifies synergistic promotion of PAHs mineralization by mixtures of the monoculture isolates. Expand
Diversity of biosurfactant producing microorganisms isolated from soils contaminated with diesel oil.
Bacterial isolates displaying substantial potential for production of biosurfactants can be applied in the bioremediation of soils contaminated with petroleum hydrocarbons. Expand
Level and degradation of Deepwater Horizon spilled oil in coastal marsh sediments and pore-water.
The results show that lighter compounds of oil are quickly degraded by microbes while the heavier fractions of oil still remain and higher inputs of organic matter from the oil spill enhance the key microbial processes associated with sulfate reducing bacteria. Expand
Characterization of a Polycyclic Aromatic Hydrocarbon–Degrading Microbial Consortium from a Petrochemical Sludge Landfarming Site
ABSTRACT Anthracene, phenanthrene, and pyrene are polycyclic aromatic hydrocarbon (PAHs) that display both mutagenic and carcinogenic properties. They are recalcitrant to microbial degradation inExpand
