Phenol biodegradation in batch systems using Cupriavidus taiwanesis 187 has been experimentally studied. To determine the various parameters of a kinetic model, combinations of rearranged equations have been evaluated using inverse polynomial techniques for parameter estimation. The correlations between lag phase and phase concentration suggest that considering phenol inhibition in kinetic anal...

petroleum-polluted soil samples from ahvaz oilfield were enriched, using three methods to detect microorganisms with different dibenzothiophene degradation capabilities. strain nisoc-03, a nitrate-reducing, oxidase negative, catalase, citrate, and urease positive, gram negative rod, showed interesting dibenzothiophene desulfurization behavior, designated as entreobacter sp. strain nisoc-03 base...

The aim of this study is to evaluate the biodegradation performance of phenol in a fixed biofilm developed in sand soil media. The parameters which had been studied and may influence the biodegradation were: a) the grain size of sand, b) the rate of flow, and c) the initial phenol loading. Laboratory scale of two columns with inner diameter of 5 cm was used. The first column was packed with fin...

Phenolic resins, phenol-formaldehyde polymers previously thought to be nonbiodegradable, are produced at an annual rate of 2.2 million metric tons in the United States for many industrial and commercial applications. Three independent lines of evidence established their biodegradability with the white-rot fungus Phanerochaete chrysosporium. Chromatic transformation of growth medium (yellow to p...

phenol and phenolic compounds are among the most recognized environmental pollutants which exist in industrial wastewater and enter the biological cycles due to the solubility in water. Bioremediation is one of the cost-effective and Eco-friendly methods for phenol removal. In this study, the most effective phenol-degrading bacterial strain was isolated and identified from the shores of the Oma...

-The use of powdered activated carbon treatment (PACT), based on simultaneous adsorption and biodegradation, is effective for treating organic toxic pollutants, present in industrial wastewaters. Removal of phenol and aniline from aqueous solutions by biological treatment alone, by adsorption on powdered activated carbon (PAC) alone and by simultaneous adsorption and biodegradation were compare...

phenol and its homologues are aromatics containing hydroxyl, methyl, amide and sulphonic groups attached to the benzene ring. these molecules are both anthropogenic and xenobiotics. phenols are environmental pollutants discharged through wastewaters from various industries. phenols are toxic to several biochemical reactions. however biological transformation of phenols to non-toxic entities exi...

The use of microbial catalysts in the biodegradation of organic compounds has advanced significantly during the past three decades. It has been found that large numbers of microbes co-exist in almost all natural environments, particularly in soils. Many natural and synthetic organic chemicals are readily biodegradable in natural environment. Biodegradation of materials involve initial proximity...

phenol is an environmental pollutant present in industrial wastewaters such as refineries, coal processing and petrochemicals products. in this study three phenol degrading bacteria from arak petrochemical complex effluent were isolated which consume phenol. molecular analysis was used to identify bacteria and isolated bacteria were identified as rhodococcus pyridinivorans (ns1), advenella faec...
