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).

To investigate the regulation of drug absorption from the small intestine by the enteric nervous system (ENS), the vascular-luminal perfusion study and the in-vitro transport study were performed by employing phenol red as a poorly absorbable model compound. The effect of ENS on the intestinal absorption of phenol red was examined by adding epinephrine, an adrenergic agonist, or bethanechol, a ...

Bacillus stearothermophilus BR219, isolated from river sediment, degraded phenol at levels to 15 mM at a rate of 0.85 mumol/h (4 x 10(6) cells). The solubilized phenol hydroxylase was NADH dependent, exhibited a 55 degrees C temperature optimum for activity, and was not inhibited by 0.5 mM phenol.

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...
