Abstract
Phenol pollution due to unprocessed effluents discharged by these industries are reported to polluted soil, groundwater and agriculture lands; and to harm the soil and plant health and productivity Phenols due to their toxicity, carcinogenicity and recalcitrant nature are listed as priority pollutants by the Environmental Protection Agency (EPA, USA) and Agency for Toxic Substances and Disease Registry (ATSDR) and hence desire effective removal (ATSDR, 1999). In addition a variety of aromatic compounds and phenols are produced by the chemical industry (Webber 1984) for utilization as pesticides, insecticides, herbicides, detergents, solvents, wood preservatives, etc. and cause pollution of air, water, soil and sediments. Accumulation of these xenobiotic above toxic concentrations in ecosystems is prevented if abiotic transformation or bioconversion to non-toxic products or biodegradation by microorganisms or microbial consortia is possible. The bacterial isolate (B1) which exhibited complete degradation of phenol (100 mg/l) after 72h using the 4-aminoantipyrine colorimetric method was selected.
