Biological degradation of phenolic compounds by a mixed bacterial culture was investigated. Pseudomonas aeruginosa and Bacillus subtilis were the two strains used in the study. pH and the temperature for the growth of bacteria was found to be 70.2 and 372C, respectively. The mixed microbial culture was able to degrade 250 mgl of phenol and wattle completely within 36 and 48 hours, respectivel...

Pseudomonas cepacia G4 grown in chemostats with phenol demonstrated constant specific degradation rates for both phenol and trichloroethylene (TCE) over a range of dilution rates. Washout of cells from chemostats was evident at a dilution rate of 0.2 h-1 at 28 degrees C. Increased phenol concentrations in the nutrient feed led to increased biomass production with constant specific degradation r...

Phenol is an important pollutant widely discharged as a component of hydrocarbon fuels, but its degradation in cold regions challenging due to the harsh environmental conditions. To date, there little information available concerning capability for phenol biodegradation by indigenous Antarctic bacteria. In this study, enzyme activities and genes encoding degradative enzymes identified using who...

• Bacillus cereus with high degradation efficiency of phenol was successfully isolated. Biochar (BC) loaded bacteria greatly accelerates biodegradation in water. BC and CABMM enhance bacterial resistance to phenol. CBAMM has great potential treating concentrated wastewater. A highly efficient phenol-degrading strain, identified as (GenBank No:MN784421) by 16S rDNA analysis, used for treatment t...

The present paper has examined the degrading ability of phenol-oxidizing bacterium, Ralstonia eutropha, for biological removal of methylene blue (MB) from aqueous solutions under aerobic conditions. Results show that MB has been extensively eliminated as a co-metabolism in the presence of supplementary carbon (glucose) and nitrogen (yeast extract and peptone) sources and the experimental observ...

Molecular and metabolomic tools were used to design understand the biodegradation of phenolic compounds in real industrial streams. Bacterial species isolated from an wastewater treatment plant a phenol production factory identified using molecular techniques. Next, potential most promising strains was analyzed presence by-product containing phenol, alfa-methylstyrene, acetophenone, 2-cumylphen...

In the present study we describe functional redundancy of bacterial multicomponent monooxygenases (toluene monooxygenase (TMO) and toluene/xylene monooxygenase (XylAM) of TOL pathway) and cooperative genetic regulation at the expression of the respective catabolic operons by touR and xylR encoded regulatory circuits in five phenol- and toluene-degrading Pseudomonas stutzeri strains. In these st...
