Distribution of petroleum degrading genes and factor analysis of petroleum contaminated soil from the Dagang Oilfield, China

Distribution of petroleum degrading genes and factor analysis of petroleum contaminated soil from the Dagang Oilfield, China

Genes that encode for enzymes that can degrade petroleum hydrocarbons (PHs) are critical for the ability of microorganisms to bioremediate soils contaminated with PHs. Distributions of two petroleum-degrading genes AlkB and Nah in soils collected from three zones of the Dagang Oilfield, Tianjin, China were investigated. Numbers of copies of AlkB ranged between 9.1 × 10(5) and 1.9 × 10(7) copies...

Characterization of Bacteria Degrading Petroleum Derivatives Isolated from Contaminated Soil and Water

Arbuscular mycorrhiza and petroleum-degrading microorganisms enhance phytoremediation of petroleum-contaminated soil.

While plants can phytoremediate soils that are contaminated with petroleum hydrocarbons, adding microbes to remediate contaminated sites with petroleum-degrading microorganisms and arbuscular mycorrhizal fungi (AMF) is not well understood. The phytoremediation of Arabian medium crude oil (ACO) was done with a Lolium multiflorum system inoculated with an AMF (Glomus intraradices) and a mixture o...

Screening of diesel oil degrading bacteria from petroleum hydrocarbon contaminated soil

Four bacterial strains were isolated from diesel contaminated soil in TVS oil depot, Trichy, Tamil Nadu. From the soil sample four morphologically different bacterial species were isolated and the active strains were Pseudomonas aeruginosa, P. putida, Arthobacter sp and Bacillus sp. The diesel degrading efficiency of isolated organisms was tested in BH medium supplemented with diesel and DCPIP ...
