Two of the largest crude oil-polluted areas in the world are the semi-enclosed Mediterranean and Red Seas, but the effect of chronic pollution remains incompletely understood on a large scale. We compared the influence of environmental and geographical constraints and anthropogenic forces (hydrocarbon input) on bacterial communities in eight geographically separated oil-polluted sites along the...
The use of petroleum based products is very widespread in our modern society. Automobiles are powered by gasoline, homes are heated with oil and industrial and manufacturing activities derive energy from various hydrocarbon fuels. The transport of petroleum products by sea, rail, tanker trucks and pipelines is common and unavoidable. Releases of petroleum hydrocarbons to the environment occur d...
Anthropogenic forces, such as petroleum spills and the incomplete combustion of fossil fuels, have caused an accumulation of petroleum hydrocarbons in the environment. The accumulation of petroleum and its derivatives now constitutes an important environmental problem. Biocatalysis introduces new ways to improve the development of bioremediation strategies. The recent application of molecular t...
The study investigated microbial population dynamics in soils of Greater Port Harcourt Area, Nigeria. involved the quantification petroleum pollutants and enumeration characterization culturable fungi bacteria. Gas Chromatograph FID method was used to quantify total hydrocarbons (TPH) soil while morphological biochemical tests were characterize microorganisms. highest TPH 9,759.37±883.36...
Constructed wetlands are in use to improve the quality of contaminated groundwaters at many sites in the USA. Target contaminants include both organic and inorganic constituents. Volatile and nonvolatile hydrocarbons are found in ground water at closed petroleum refinery sites, and in leachates from landfills. Polycyclic aromatic hydrocarbons are pollutants at many sites. Chlorinated organics o...
Bioremediation can be defined as any process that uses microorganisms or their enzymes to remove and or neutralize contaminants within the environment (i.e., within soil and water) to their original condition. Bioremediation can be employed to remediate specific types of contaminants such as; petroleum hydrocarbons, polycyclic aromatic hydrocarbons (PAH), polychlorinated biphenyl’s (PCB), chlor...
Introduction and purpose: Soil contamination by petroleum is mostly resulted from oil exploration, refining processes, leaking of oil products from storage tanks, leaking from pipelines due to pipe friction and decay, refinery wastewater discharge and agricultural irrigation with such materials. Sodium persulfate (Na2S2O8), which is a chemical oxidant, could be activated in ...
Dietzia sp. 111N12-1, isolated from the seawater of South China Sea, shows strong petroleum hydrocarbons degradation activity. Here, we report the draft sequence of approximately 3.7-Mbp genome of this strain. To the best of our knowledge, this is the first genome sequence of Dietzia strain isolated from the sea. The genome sequence may provide fundamental molecular information on elucidating t...
