Phenol biodegradation under aerobic conditions and its effect on the nitrification process were studied, first in batch assays and then in an activated sludge reactor. In batch assays, phenol was completely biodegraded at concentrations ranging from 100 to 2500 mg l(-1). Phenol was inhibitory to the nitrification process, showing more inhibition at higher initial phenol concentrations. At initi...

biodegradation of phenol is a major focus of toxic organic compound degradation by microorganisms isolated from polluted areas. an increasing number of bacteria and fungi possessing unique biodegradation capabilities have been isolated in recent years. in this study a new isolate, rhodococcus erythropolis sko-1, from polluted soils in the tehran oil refinery region, is reported. identificati...

phenol and phenol compounds are environmental pollutants present in industrial wastewaters such as, coal tar, oil refineries and petrochemical plants exist. phenol removal from industrial effluent is extremely important in protection of environment. recently phenol biodegradation has been considered. marine bacteria are the most important phenol biodegrader. in this study, the phenol-degrading ...

horseradish peroxidase was encapsulated in calcium alginate for the purpose of phenol removal. considering enzyme encapsulation efficiency, retention activity and enzyme leakage of the capsules, the best gelation condition was found to be 1 % w/v of sodium alginate solution and 5.5 % w/v of calcium chloride hexahydrate. upon immobilization, ph profile of enzyme activity changes as it shows high...

Phenol and its derivatives are pollutant compounds that are present in the wastewater of many industries. The objective of this study was to investigate the photocatalytic degradation of phenol in water containing various concentrations of sodium chloride. A laboratory study was conducted to evaluate the performance of UV/ZnO process on the efficiency of phenol removal from saline water with Zn...

Maclagan (1944a) demonstrated that phenol and certain derivatives when dissolved in barbiturate buffer at pH 7.8 produced a turbidity with human sera. He observed that under specified conditions sera from normal persons gave a negligible turbidity, and the most marked turbidities occurred with sera from patients suffering from parenchymatous liver damage. The concentrations of phenol or phenol ...
