Trichloroethene is degraded by ammonia-oxidizing bacteria. In the absence of ammonia, TCE transformation proceeds at moderate rates. Under the experimental conditions tested, the presence of PCE and cis-DCE, competitive ...

Recent investigations indicate that 2,4,6-trinitrotoluene (TNT) is rapidly transformed in an aquatic environment by the action of photosynthetic organisms. Several plant species from a variety of culture conditions were ...

Studies are presented investigating the metabolism of 2,4,6-trinitrotoluene (TNT) by Clostridium acetobutylicum. When incubated with a batch culture of acetogenic Clostridium acetobutylicum, TNT was reduced through ...

The ability of subsurface microbial populations to degrade organic contaminants is affected by nutrient availability. A study was performed to measure the change in microbial ecology of a weathered JP-4 jet fuel contaminated ...

In this work, rapid TNT ($>$150 mg/L) transformation by Clostridium acetobutylicum via a reductive pathway to monoaminonitrotoluenes, diaminonitrotoluenes, and on to undetectable end products was observed. The maximum ...

Biosurfactants have potential for enhancement of in situ biorestoration. A study was performed to characterize biosurfactant production by microbes from several subsurface environments contaminated with petroleum hydrocarbons. ...

Biosurfactants produced by subsurface bacteria may potentially enhance in situ bioremediation. A study was performed to characterize the production and enhancement of production of biosurfactants by 37 gasoline-degrading ...

A literature search and laboratory treatability study were conducted to determine the potential of commercial surfactants to enhance the bioremediation of PAH-contaminated sediments. Phenanthrene was used as a model PAH ...
