Biodegradation of Phenol by Newly Isolated Phenol-degrading Bacterium Ralstonia sp. Strain PH-S1
A newly phenol-degrading bacterium, identified as Ralstonia sp. strain PH-S1, was isolated from oil-contaminated soil in Khark Island. It was isolated by a multistep enrichment and screening technique on mineral medium (MM) containing 100 mg.l-1 of phenol as the sole source of carbon. The bacterium was able to degrade up to 1100 mg.l-1 of phenol but the cell growth decreased with higher concent...
متن کاملIsolation of phenol-degrading Bacillus stearothermophilus and partial characterization of the phenol hydroxylase.
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.
متن کاملSelective Amplification of Catechol 2, 3 Dioxygenase Gene from Phenol Degrading Alcaligenes Sp D2 Isolated from Soil
Catechol 2, 3-Dioxygenase transforms catechol by meta cleavage to 2hydroxymuconate semialdehyde. The meta pathway is functional in the microbial degradation of phenol and many such organic compounds. In the present study an attempt was made to isolate and purify catechol 2, 3dioxygenase from a phenol degrading Alcaligenes sp d2. The enzyme in the culture extract was precipitated at 80% ammonium...
متن کاملIsolation and characterization of phenol degrading bacteria from Persian Gulf
Phenol and phenol compounds are environmental pollutants present in industrial wastewaters such as, coal tar, oil refineries and petrochemical plants exist. Phenol removal from industrial effluent is extremely important in protection of environment. Recently phenol biodegradation has been considered. Marine bacteria are the most important phenol biodegrader. In this study, the phenol-degrading ...
