Three types of phenol and p-cresol catabolism in phenol- and p-cresol-degrading bacteria isolated from river water continuously polluted with phenolic compounds

Degradation of phenol and p-cresol in reactors

The effects of hydraulic retention time (HRT) and phenol concentration on the degradation of phenol and p-cresol in wastewater were investigated in two respective UASB (upflow anaerobic sludge blanket) reactors with effluent recirculation at 37 oC for over 440 days. After acclimation, nearly all the phenol and p-cresol at moderate concentrations could be degraded without carbohydrate as a co-su...

Phenol and Cresol

Biological removal of p-cresol, phenol, p-hydroxybenzoate and ammonium using a nitrifying continuous-flow reactor.

Phenolic compounds biodegradation and its effect on the nitrification process were studied. A continuous stirrer tank reactor was operated in four stages, and phenolic compounds were fed as sequential way. In the first stage, at loading rate of 220 mg NH(4)(+)-N/Ld, the consumption efficiency was of 91%, being the product, nitrate. After that, p-cresol was fed at 53 mg C/Ld, reaching removal ef...

Isolation and identification of phenol degrading bacteria from Kor river and their growth kinetics assay

Background : Phenol and it’s derivatives were removed by physicochemical methods in the past but nowadays biological treatment has priority. Bacteria with the rapid proliferation in the presence of phenol and it’s derivatives can remove them in a good manner. The aim of this project is isolation and identification of bacteria that degrade phenol from water and sediment of Kor river and also inv...

Phenol and p-cresol accumulated in uremic serum measured by HPLC with fluorescence detection.

We developed a simple and sensitive high-performance liquid chromatographic (HPLC) method that uses fluorescence as a detector for quantifying serum phenol and p-cresol in uremic patients on hemodialysis. Identification of phenol and p-cresol was confirmed by liquid chromatography/mass spectrometry. Because the HPLC method requires only simple extraction by ethyl acetate and does not require fu...
