Crude oil contamination of soil and water resources is a widespread issue. The present study evaluated the degradation aliphatic hydrocarbons (C 11 –C 36 ) in crude by 17 bacteria isolated from oil–contaminated soil. results suggested that Pseudomonas sp. Bacillus amyloliquefaciens were best hydrocarbon-degrading presence surfactant Tween-80 (0.1% w/v). Based on investigation previous study, + ...

The contamination of crude oil in soil matrices is a persistent problem with negative repercussions because the recalcitrant, hazardous, and mutagenic properties its constituents. To mitigate effect soil, use microorganisms cheap feasible option. In current study, bacterial species from numerous polluted field surfaces were isolated examined for their ability to degrade oil. Random samples hydr...

Marine subsurface environments such as deep-sea sediments, house abundant and diverse microbial communities that are believed to influence large-scale geochemical processes. These processes include the biotransformation and mineralization of numerous petroleum constituents. Thus, microbial communities in the Gulf of Mexico are thought to be responsible for the intrinsic bioremediation of crude ...

Continuous increase in oil pricing is not only causing difficulties to consumer but the imbalance in demand and supply is impacting the producer and refineries also. Consumer may adjust the demand dynamically as per the price fluctuation but oil major cannot change the production so dynamically. The recommended solution is the latest technology which could optimize the production, meeting the i...

A method is described for the systemic identification and quantitative analysis of nitrogen-containing compounds and other non-hydrocarbons in crude oils. The pre-fractionation of a crude oil sample into 7 fractions was performed by di-adsorption column chromatography using neutral aluminum oxide and silica gel. A subsequent high-resolution separation of individual components was achieved by us...

Biosurfactants or surface-active compounds are produced by microoaganisms. These molecules reduce surface tension both aqueous solutions and hydrocarbon mixtures. In this study, isolation and identification of biosurfactant producing bacteria were assessed. The potential application of these bacteria in petroleum industry was investigated. Samples (crude oil) were collected from oil wells and 4...

Abstract Petroleum-hydrocarbons spilt in surface seawater may pose potential threats to the corrosion of steel infrastructures. We show that crude oil accelerated mainly by accelerating microbiologically influenced (MIC). Crude led dominance marine oil-degraders including Alcanivorax and Marinobacter both rust, rather than sulfate-reducing bacteria (SRB) which dominated rust microbial community...
