Field extraction of a transient intermediary metabolite indicative of real time in situ naphthalene biodegradation

Article Abstract:

In situ contaminant biodegradation has been the subject of numerous studies because of its relevance to contemporary society. However, it was only recently when scientists used unstable intermediary metabolites from field samples to study in situ real time biodegradation of contaminants. Herein, in situ naphthalene biodegradation is investigated, with 1,2-dihydroxy-1,2-dihydronaphthalene as an indicator of metabolic change and real time biodegradation.

Epistemology of environmental microbiology

Article Abstract:

An analysis of knowledge on environmental microbiology reveals that constraints largely result from methodologies that do not completely simulate field characteristics. The study also reveals that these constraints are overcome by innovations that make use of new technology that facilitate identification of processes, organisms involved, biological mechanisms, among others.

Metabolic adaption and in situ attenuation of chlorinated ethenes by naturally occurring microorganisms in a fractured dolomite aquifer near Niagara Falls, New York

Article Abstract:

Microorganisms present in a fractured dolomite aquifer were found effective in transforming trichloroethene (TCE) to ethene. The ability to dechlorinate TCE appears to have resulted from an adaptation by the microorganisms. The transformation appears to be driven by electron donors, which result from the presence of hydrocarbons in the aquifer.
