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...

Transmembrane signaling by chemoattractants in leukocytes appears to require activation of phosphoinositide metabolism with subsequent generation of the second messenger substances, inositol(1,4,5)trisphosphate and diacylglycerol. In addition, previous studies have shown that conditions which lead to an intracellular increase in S-adenosylhomocysteine (AdoHcy), a by-product and competitive inhi...

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 ...

This procedure is the method of choice for purification of mammalian genomic DNA from monolayer cultures when large amounts of DNA are required, for example, for Southern blotting. Approximately 200 µg of mammalian DNA, 100-150 kb in length, is obtained from 5 × 107 cultured aneuploid cells (e.g., HeLa cells).
