Petroleum hydrocarbons are important energy resources used by industry and in our daily life, whose production contributes highly to environmental pollution. To control such risk, bioremediation constitutes an environmentally friendly alternative technology that has been established and applied. It constitutes the primary mechanism for the elimination of hydrocarbons from contaminated sites by ...

In this study, the in-vitro antifungal activity and phytochemical analysis of Schizophyllum commune extracts have been investigated. The antifungal activity was tested against 11 species of selected wood degrading fungi of rubberwood. The results showed that water, methanol and ethanol extracts significantly inhibited the growth of wood degrading fungi with minimum inhibitory concentration (MIC...

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.

Cometabolism of trichloroethylene (TCE) by phenol-fed enrichments was evaluated in four reactors with distinct phenol feeding patterns. The reactors were inoculated from the same source, operated at the same average dilution rate, and received the same mass of phenol over time. Only the timing of phenol addition differed. Reactor C received phenol continuously; reactor SC5 received phenol semic...

A bacterium, Pseudomonas aeruginosa (ATTC27853), was investigated for its ability to grow and to degrade phenol as sole carbon source, in aerobic batch culture. The parameters which affect the substrate biodegradation such as the adaptation of bacteria to phenol, the temperature, and the nature of the bacteria were investigated. The results show that for a range of temperature of 30 to 40°C, th...

biodegradation of phenol is a major focus of toxic organic compound degradation by microorganisms isolated from polluted areas. an increasing number of bacteria and fungi possessing unique biodegradation capabilities have been isolated in recent years. in this study a new isolate, rhodococcus erythropolis sko-1, from polluted soils in the tehran oil refinery region, is reported. identificati...

Introduction. The toxic nonprotein amino acid mimosine present in Leucaena leucocephala is degraded by rumen bacteria to produce another toxic compound, 3-hydroxy-4(lH)-pyridone (3,4-dihydroxypyridine, or 3,4-DHP). In some, but not all, geographic areas ruminants are colonized by bacteria that degrade 3,4-DHP, and actions of these microbes protect their host animals from leucaena toxicosis (Jon...
