Heart disease is a leading cause of morbidity and mortality in the United States with diet being major contributor. As solution, fish rich omega-3 fatty acids recommended. In this study, impact brackish water on quality, was done by sampling canal Edinburg, Texas. Canal membrane filtered cultured bacteriological media. Pure cultures were phenotypically identified, isolates confirmed BD Phoenix ...

2-Aminomuconate, an intermediate in the metabolism of tryptophan in mammals, is also an intermediate in the biodegradation of nitrobenzene by Pseudomonas pseudoalcaligenes JS45. Strain JS45 hydrolyzes 2-aminomuconate to 4-oxalocrotonic acid, with the release of ammonia, which serves as the nitrogen source for growth of the microorganism. As an initial step in studying the novel deamination mech...

PCBs (polychlorinated biphenyls) had been widely used for a variety of industrial purposes. Due to their classification as persistent organic pollutants, their production was banned in 1979. However, PCBs-polluted sites are still present worldwide, thus leading to the need for environmental remediation strategies for PCB compounds. Several PCBs-degrading bacteria had been previously isolated fr...

Pseudomonas pseudoalcaligenes KF707 is naturally resistant to the toxic metalloid tellurite, but the mechanisms of resistance are not known. In this study we report the isolation of a KF707 mutant (T5) with hyperresistance to tellurite. In order to characterize the bacterial response and the pathways leading to tolerance, we utilized Phenotype MicroArray technology (Biolog) and a metabolomic te...

Abstract In this paper, we report the thermal adaptation of Pseudomonas pseudoalcaligenes, characterized as changes in growth parameters. Six clones derived from a single colony of P. pseudoalcaligenes were cultured in two different temperature regimes for 10 months, with three clones forming the control group, cultured at a constant temperature, and another three clones forming the high-temper...

Total community DNA from 29 noncontaminated soils and soils impacted by petroleum hydrocarbons and chloro-organics from Antarctica and Brazil were screened for the presence of nine catabolic genes, encoding alkane monooxygenase or aromatic dioxygenases, from known bacterial biodegradation pathways. Specific primers and probes targeting alkane monooxygenase genes were derived from Pseudomonas pu...
