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...

We identified an open reading frame, designated phcS, downstream of the transcriptional activator gene (phcR) for the expression of multicomponent phenol hydroxylase (mPH) in Comamonas testosteroni R5. The deduced product of phcS was homologous to AphS of C. testosteroni TA441, which belongs to the GntR family of transcriptional regulators. The transformation of Pseudomonas aeruginosa PAO1c (ph...

In many nearshore marine systems, microalgae can be chronically exposed to anthropogenic and biogenic phenolic and halophenolic compounds that accumulate in surficial sediments. Although biodegradation of some phenolic compounds has been demonstrated in freshwater algae, this capability has not been tested in marine species. We examined a ubiquitous marine diatom, Thalassiosira sp. HP9101, for ...

Extraction of fresh sporophores of the fungus Agaricus xanthodermus yields 4,4'-dihydroxy-azobenzene, phenol, p-quinol, and 4,4'-dihydroxybiphenyl. This is the first report of an azo compound arising endogenously in nature, while phenol, p-quinol and 4,4'-dihydroxybiphenyl have not previously been isolated from higher fungi. Phenol is present in fruitbodies in sufficiently high concentration to...

Li Si, Kong Ruixue, Sun Lin, Li Sifan, Yang Shuangchun* (Liaoning Shihua University. Fushun, Liaoning, China. 113001) Abstract—Industrial wastewater is a kind of wastewater that generate in the industrial production process. The wastewater from refining and coal carbonization contains high concentration of phenols pollutants. In this paper, study on phenol treatment methods in industrial wastew...
