Bacterial degradation of organic pollutants in soil has been studied extensively but little is known about the availability and degradation of pollutants by bacterial resident on leaf surfaces. Here, we examined availability and degradation of phenol on leaves by introduced cells of a known phenol degrader and by natural microbial communities. Phenol-responsive gfp-expressing Pseudomonas fluore...

Background: Phenol is an aromatic pollutant in industrial wastes that in combination with salts is highly toxic for all forms of life. Phenol elimination is the foremost challenge to meet the goal of pollutant-free environment. Objective: The present study was carried out to isolate phenol degrading bacteria which can degrade phenol under saline conditions and...

The changes in the cellular fatty acid composition of Stenotrophomonas maltophilia KB2 during co-metabolic degradation of monochlorophenols in the presence of phenol as well as its adaptive mechanisms to these compounds were studied. It was found that bacteria were capable of degrading 4-chlorophenol (4-CP) completely in the presence of phenol, while 2-chlorophenol (2-CP) and 3-chlorophenol (3-...

Eighteen 4-t-octylphenol-degrading bacteria were isolated and screened for the presence of degradative genes by polymerase chain reaction method using four designed primer sets. The primer sets were designed to amplify specific fragments from multicomponent phenol hydroxylase, single component monooxygenase, catechol 1,2-dioxygenase and catechol 2,3-dioxygenase genes. Seventeen of the 18 isolat...

Two kinds of phenol-degrading denitrifying bacteria, Azoarcus sp. strain CC-11 and spiral bacterial strain CC-26, were isolated from the same enrichment culture after 1 and 3 years of incubation, respectively. Both strains required ferrous ions for growth, but strain CC-26 grew better than strain CC-11 grew under iron-limited conditions, which may have resulted in the observed change in the phe...

phenol is an environmental pollutant present in industrial wastewaters such as refineries, coal processing and petrochemicals products. in this study three phenol degrading bacteria from arak petrochemical complex effluent were isolated which consume phenol. molecular analysis was used to identify bacteria and isolated bacteria were identified as rhodococcus pyridinivorans (ns1), advenella faec...

New phenol degrading bacteria with high biodegradation activity and high tolerance were isolated as Burkholderia cepacia PW3 and Pseudomonas aeruginosa AT2. Both isolates could grow aerobically on phenol as a sole carbon source even at 3 g/l. The whole-cell kinetic properties for phenol degradation by strains PW3 and AT2 showed a Vmax of 0.321 and 0.253 mg/l/min/(mg protein), respectively. The ...
