Microorganisms play a vital role incleaning up the environment by degrading the pollutants like monoaromatics andpolycyclic aromatic hydrocarbons(PAHs) which are toxic andare among the most prevalent and persistent pollutants inthe environment. Soil contaminated with petroleum generally contains a mixtureof polycyclic aromatic hydrocarbons (PAHs) and heterocyclic aromatics.

The bio-recovery of three different oil-polluted tropical soils – RS (oil-polluted soil sample from River state), LS (soil sample from NNPC depot, Lagos) and POS (oil-polluted soil sample from Oriade L.G.A., Lagos) by manure amendment was studied for eight weeks. The rates of crude oil biodegradation after manure application as quantified by Gas chromatographic analysis of residual total petroleum hydrocarbon (TPH) showed the same trend of decrease in the total petroleum hydrocarbons in both the LS and RS series.

The phenomenon of the oil spill in the marine ecosystem is one of the major issues which causes the introduction of petroleum hydrocarbon pollutants and leads to a significant threat to the environment. It can occur either naturally or from anthropogenic sources such as those caused by tanker accidents, refineries, drilling operations, or even storage facilities.

This article presents a study of the bacteria bioremediation characters and their heavy metal and antibiotic tolerance from the petroleum contaminated soil located in industrialized areas of Chhattisgarh, India. Soil sediments were characterized by FTIR for the presence of aromatic compounds and further the heterotrophic and fuel degrader counts was estimated. The strains characterized were predominantly from the Bacillus species which showed mixed resistance patterns against antibiotics and heavy metals.

Phenol is a toxic hydrocarbon for nervous system, kidneys, liver, muscles and immune system. It is also mutagenic and possibly carcinogenic. Phenol containing- pollutants are dangerous and spread worldwide in the industrial effluents.The present study aimed to isolate a potent microorganism able to degrade phenol, as well as to evaluate the nutritional and environmental conditions that lead to its maximum degradation. A yeast isolated from petroleum-contaminated soil on MSM supplemented with phenol as sole carbon source, was identified by 28S rDNA sequencing.

Petroleum is a complex mixture composed primarily of aliphatics, alicyclics and aromatic hydrocarbons. This study was to evaluate the potentials of native bacterial population of wastewater environment with the ability for bioremediation of petroleum hydrocarbon polluted natural environment. A fresh water ecosystem west of Lagos state university, Ojo campus that has the history of being fed with both domestic wastewater and spent diesel oil served as source of bacterial samples. Serial dilution technique and total heterotrophic bacterial count for the wastewater was evaluated.

This work focused on monitoring CO2 production, microbial growth and residual hydrocarbon concentration during bioremediation experiments performed on laboratory soil microcosms. A natural soil was artificially contaminated with hexadecane and adjusted with inorganic nutrients to stimulate biodegradation. Microbial growth, CO2 production and residual hexadecane were periodically monitored at different soil water contents ranging from 0.15 to 0.25 g water g -1 of dry soil and at different temperatures ranging from 20 to 25 oC.

Petroleum-based products are the major source of energy for industry and daily life. Leaks and accidental spills occur regularly during the exploration, production, refining, transport, and storage of petroleum and petroleum products. Crude oil-impacted tropical soil and natural water samples (0 - 30cm depth) were obtained from the Niger Delta, Nigeria. A total of twenty seven bacterial species of relevance in bioremediation were isolated and characterized using standard and conventional methods. The predominant species belong to the genera Pseudomonas and Proteus.

Bacteria able to produce biosurfactants can use petroleum-based hydrocarbons as a carbon source. Herein, four biosurfactant-producing Pseudomonas aeruginosa strains, isolated from oil-contaminated saline soil, were combined to form a bacterial consortium. The inoculation of the consortium to contaminated soil alleviated the adverse effects of salinity on biodegradation and increased the rate of degradation of petroleum hydrocarbon approximately 30% compared to the rate achieved in non-treated soil.

Bioremediation, the use of microorganisms, by virtue of their bioconcentrating and metabolic properties, to degrade, sequester, or remove environmental contaminants, has about a 45-year history. Such uses of microorganisms for this purpose now involve freshwater, marine, and terrestrial environments. Bioremediation is a multidisciplinary area of knowledge and expertise that involves basic and applied science. Microbiologists, chemists, toxicologists, environmental engineers, molecular biologists, and ecologists have made major contributions to this subject....
