Anaerobic transformation of chlorophenols in methanogenic sludge unexposed to chlorophenols
Chemosphere, 2000Transformation of all 19 chlorophenol (CP) isomers was investigated in a laboratory anaerobic methanogenic sludge that had not been exposed to synthetic chemicals. Concentration of CP was analyzed over time to calculate disappearance rate constants using first-order reaction kinetics and all possible CP degradation pathways were estimated.

Function Analysis of Chlorophenol Monooxygenase for Chlorophenol Degradation
Advanced Materials Research, 20144-Chlorophenol is well-known as an extensively used antiseptic, and it may cause severe damage to the environment and human health. 4-Chlorophenol can be biologically degraded by Arthrobacter chlorophenolicus A6, which can be attributed to the cphC-I and cphB genes of the microorganism that encode for a two-component flavin-diffusible monooxygenase (TC-

Chlorophenol Exposure in Sawmills
American Industrial Hygiene Association Journal, 1985Personnel exposures to chlorophenols were measured in ten Finnish sawmills where a chlorophenolate salt formulation was used for the blue stain control of sawed wood. The concentrations of chlorophenols in the air were usually well below the occupational limit value of 0.5 mg/m3. However, high concentrations (above 10 mg/m3) were measured inside heated

Letters in Applied Microbiology, 1995
A Gram-negative aerobic bacterium capable of using 2-chlorophenol (2-CP), 3-chlorophenol (3-CP) and 4-chlorophenol (4-CP) as sole carbon sources was isolated and characterized. The bacterium, designated LD1, was identified to be a Pseudomonas pickettii strain. LD1 was able to totally degrade and dechlorinate 2-CP (initial concentration: 1.51 mmol l-1),

Genetic Activity of Chlorophenols and Chlorophenol Impurities
1978Studies were made of the genetic activity of 2,4,6-trichlorophenol, pentachlorophenol, and their impurities: 2,3,7,8-tetrachlorodibenzofuran 2,4,4′,6-tetrachlorodiphenyl ether 2,4,4′, 5-tetrachlorodiphenyl ether 4,5,6-trichloro-2-(2,4-dichlorophenoxy)phenol, (Cl5-predioxin) 4-chloro-2-(2,4-dichlorophenoxy)phenol, (Cl3 ...

The transformation of chlorophenols by lactoperoxidase
Biochimica et Biophysica Acta (BBA) - General Subjects, 1985The lactoperoxidase-catalyzed transformations of penta-,2,3,4,6-tetra-, 2,4,6-tri-, 2,4-di- and 4-monochlorophenol were followed spectrophotometrically. Apparent stoichiometries of chlorophenol:H2O2 ranged from 1:1 for the tri- and tetrachlorophenol at pH7 to 5:2 for pentachlorophenol at pH 4.

Microbial Degradation of Chlorophenols
2016Chlorophenols (CPs) are hazardous pollutant that are commonly encountered as major constituents of several types of wastewater such as industrial, refinery and pharmaceutical wastewater. They are also exposed to the environment in the form of chloro-based pesticides.

Enzymatically mediated incorporation of 2-chlorophenol and 4-chlorophenol into humic acids
Chemosphere, 1994Abstract A possible route to chlorinated humic substances in the environment, is an indirect chlorination of humic material by enzymatically mediated incorporation of low molecular weight organo-chlorine compounds into the humic skeleton. The enzymatically mediated incorporation of 2-chlorophenol and 4-chlorophenol into humic acids by Horseradish ...
