In this study, among the 21 diesel-degrading bacteria that were isolated from an oil-polluted area in Fars (Iran), 6 bacterial strains were tested for their capability to metabolize and grow on diesel oil by degrading its hydrocarbons content. The biochemical characteristics and 16S rRNA sequence analysis of diesel-degrading bacteria showed that these strains were related to the genus Pseudomon...

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 ...

A variety of factors, including concentration of oil, antibiotics, dyes, and inoculum washes, were examined to determine their effect on the total counts of microorganisms on oil-containing media. The media found to be best for enumerating petroleum-degrading microorganisms contained 0.5% (vol/vol) oil and 0.003% phenol red, with Fungizone added for isolating bacteria and streptomycin and tetra...

some properties of compounds in degrading bacteria are required for biodegradation of contaminants to higher performance. those strains which have a high percentage of these features are more effective at biodegradation. the present experiments were designed to measure these parameters. in this study, measurement of cell surface hydrophobic-degrading bacteria was designed which oil was separate...

Five years after the 1997 Nakhodka oil spill in the Sea of Japan, seven bacterial strains capable of utilizing the heavy oil spilled from the Nakhodka Russian oil tanker were isolated from three coastal areas (namely Katano Seashore of Fukui Prefecture, Osawa and Atake seashores of Ishikawa Prefecture) and the Nakhodka Russian oil tanker after a 5-year bioremediation process. All bacterial stra...

polycyclic aromatic hydrocarbons (pahs) are one of the most common contaminants found in soil. pahs exhibit a significant concern because of their toxicity, carcinogenic, teratogenic and mutagenic properties. using microorganisms for cleaning the pollution of soil can be cheap, effective and can provide environmental immunity. the goal of this study is to isolate and identify phenanthrene degra...

petroleum hydrocarbons are among the major organic environmental pollutants whose toxicity and carcinogenicity effects have raised great concerns while the numerous available physical and chemical methods to remove petroleum hydrocarbons are rarely employed due to their extreme costs and harmful side effects, biological methods, including phytoremediation, have attracted wide attention during t...

background: polychlorinated biphenyls (pcbs) are synthetic aromatic compounds containing two benzene rings with one to ten chlorine atoms. there are concerns about the health risks of these compounds in the environment due to their toxicity, persistence, and biological accumulation. pcbs wastes must be treated before being discharged to the environment because they will pollute the water, soil,...
