Bacteria3
Pseudomonas is a genus of Gram-negative , rod-shaped bacteria. (kenyon.edu)
5 Pseudomonas contains a number of scientifically and medically studied bacteria, such as the opportunistic pathogen P. aeruginosa , and there is increasing availability of Pseudomonas strain genome sequences. (kenyon.edu)
Plasmid pRO1957 contains a 26.5-kb BamHI restriction endonuclease-cleaved DNA fragment cloned from the chromosome of Pseudomonas pickettii PKO1 that allows P. aeruginosa PAO1c to grow on toluene, benzene, phenol, or m-cresol as the sole carbon source. (nih.gov)
13 Pseudomonas stutzeri's relative abundance was seen as a result of its ability to utilize aromatic hydrocarbons such as xylene, toluene, phenol, as well as polycyclic aromatic hydrocarbons , such as naphthalene . (kenyon.edu)
Phenol2
Advanced oxidation processes (APOs) of aromatic compounds, particularly of phenol, yield several benzene derivatives, such as hydroquinone, catechol, and resorcinol, as intermediate metabolites of its transformation. (hindawi.com)
The formation of hydroquinone and -benzoquinone at early stages of phenol oxidation increases the toxicity of phenol wastewaters, showing that these compounds were more toxic and less degradable than the original pollutant [ 2 ]. (hindawi.com)
Stutzeri5
In a metagenomic analysis of the microbial population in petroleum pipelines, Pseudomonas stutzeri was detected as the most abundant hydrocarbon degrading organism. (kenyon.edu)
Species in the bacterial genus Pseudomonas present high potential for hydrocarbon degradation due to their metabolic diversity, their abundance in microbial communities, and their resistance to chemical remediation agents present at contamination sites. (kenyon.edu)
10 Pseudomonas species have been found to dominate hydrocarbon degrading bacterial communities even in the Artic-an environment that entails extreme temperature conditions, limited availability of nutrients such as nitrogen, and low levels of available water. (kenyon.edu)
In these mainly marine organisms, above a certain population density, light is produced continuously by the action of bacterial luciferase (LuxAB), which oxidizes a long-chain aldehyde such as tetradecanal in the presence of FMNH 2 and oxygen. (nih.gov)
Species5
3 There are currently 218 species assigned to Pseudomonas and the genus has considerable heterogeneity. (kenyon.edu)
The metabolic versatility of the genus allows Pseudomonas species to inhabit a wide variety of environments. (kenyon.edu)
