TL;DR: No correlation was found between the prevalence of hydrocarbon-degradative genotypes and biological activities (respiration, fluorescein diacetate hydrolysis, lipase activity) or numbers of culturable hydrocarbon -degrading soil microorganisms; there also was no correlation between the numbers of hydro carbon degraders and the contamination level.

TL;DR: The presence of multiple alkane hydroxylases in the two rhodococcal strains is reminiscent of other multiple-degradative-enzyme systems reported in Rhodococcus.

TL;DR: The colony hybridization technique was used to determine the prevalence of each of the alk genes and determine their relative abundance in culturable cold-adapted and mesophilic populations from eight of the polar soils, indicating that Acinetobacter spp.

TL;DR: A novel two- component todST system, which activates expression of the toluene degradation (tod) pathway in Pseudomonas putida F1, is described, the first report of a two-component system that regulates aromatic metabolism in bacteria.

TL;DR: A significant shift in the microbial community structure in Alpine soils following contamination is demonstrated, and more potentially novel phylotypes were found in the pristine soils than in the contaminated soils.
