Background: Phenol is an aromatic pollutant in industrial wastes that in combination with salts is highly toxic for all forms of life. Phenol elimination is the foremost challenge to meet the goal of pollutant-free environment. Objective: The present study was carried out to isolate phenol degrading bacteria which can degrade phenol under saline conditions and...

The coking process produces great volumes of wastewater contaminated with pollutants such as cyanides, sulfides and phenolics. Chemical and physical remediation of this wastewater removes the majority of these pollutants; however, these processes do not remove phenol and thiocyanate. The removal of these compounds has been effected during bioremediation with activated sludge containing a comple...

OBJECTIVES Many conservative methods have been applied in the treatment of pilonidal sinus disease (PSD). The most commonly used conservative treatment is 80% phenol solution. Our observations demonstrated that 80% phenol solution caused much destruction in the sacrococcygeal region. DESIGN In this study low concentrations of phenol were used with the aim of reducing the unwanted side-effects...

This research demonstrated the microbial treatment of concentrated phenol wastes using a two-phase partitioning bioreactor (TPPB). TPPBs are characterized by a cell-containing aqueous phase and an immiscible and biocompatible organic phase that partitions toxic substrates to the cells on the basis of their metabolic demand and the thermodynamic equilibrium of the system. Process limitations imp...

Studies reported here confirm that the pH indicator, phenol red, acts as a weak estrogen and reexamine the significance of estrogenic and antiestrogenic effects on growth of the human breast cancer cell lines ZR-75-1 and T-47-D in the absence of phenol red. Removal of phenol red reduces but does not immediately eliminate cell growth in the absence of estradici. Basal cell growth can be reduced ...

Phenol is a common wastewater contaminant from various industrial processes, including petrochemical refineries and chemical compounds production. Due to its toxicity to microbial activity, it can affect the efficiency of biological wastewater treatment processes. In this study, the efficiency of an Anaerobic Sequencing Batch Reactor (ASBR) fed with increasing phenol concentrations (from 120 to...

Phenolic compounds are widely used in industries and other daily life for various purposes and enter in the industrial effluent and ultimately the final disposal of this effluent which contain phenol compounds are different water bodies which may get contaminated through the continuous disposal of the these effluents. Highly toxicity and carcinogenicity of these compounds can cause considerable...

The intracardiac pathways carrying the cardiovascular reflex responses mediated by cardiac sympathetic and vagal afferent fibers were examined in this study. We investigated the response to epicardial applications of bradykinin (5 micrograms) and nicotine (50 micrograms) before and after regional epicardial applications of 85% phenol in chloralose anesthetized open-chest dogs. Bradykinin stimul...
