Volatile organic compounds (VOCs) are abundant in nature and can occur in various forms in a wide variety of sources. Petroleum is one of the major sources of VOCs. Petroleum being the most widely used energy resources of the world, often released to…
Sustainable treatment of petroleum oil sludge still remains as a major challenge to petroleum refineries. Bioremediation is the promising technology involving bacteria for simultaneous production of biosurfactant and followed by degradation of…
Various aspects of the oil fields in terms of microbial activity (souring, biocorrosion, etc.) and oil production (polymer flooding, etc.) have been evaluated through a variety of experiments. The primary step to study these properties in the…
In this work, an experimental investigation on removing crude oil from a stainless steel tube using a biosurfactant such as emulsan was studied. The emulsan used in this study was produced byAcinetobacter calcoaceticusPTCC1318. The produced emulsan…
Nowadays, we can choose a carrier bag made of traditional LDPE or a biodegradable polymer to pack vegetables, bakery products, and other products in more and more shops. However, the customers and the selective waste collection system are not yet…
Currently, research on oily sludge treatment mainly focuses on optimizing the deoiling effect and research on the deoiling mechanism, and the influence of petroleum components on the properties and treatment of oily sludge is rarely considered.…
New bacterial strain BN66 was isolated by selective enrichment, identified as Bacillus cereus and proved to degrade crude oil, together with biosurfactant synthesis. Free and cryogel immobilized Bacillus cereus cells were involved in a crude oil…
W12# strain, which could produce biosurfactants with liquid wax as sole carbon source, was screened from oil-contaminated soil in Liaohe oilfield. Its effect on crude oil fluidity improvement was studied. Experimental results showed that W12# strain…
To investigate the influence of microbial wax removal and viscosity reduction technologies on the fluidity of waxy crude oil, this study took the waxy crude oil from China's Daqing Oilfield as the experimental object for microbial wax removal and…
This study presents a novel and dynamic strategy to enhance rhamnolipid and sophorolipid production using isolated Pseudomonas aeruginosa and Starmerella bombicola, respectively, from an Egyptian oil field. The optimum productivity of rhamnolipid and…
In the present study, the biosurfactant production dynamics of Pseudomonas sp. IITISM 19, an indigenous bacterium was investigated and, the strain was evaluated for its crude oil biodegradation potential. The biosurfactant produced during…
This study examined the effect of voltage variation, the distance between electrodes and the application of a biosurfactant on the bio-electrokinetic remediation of soil contaminated with petrochemicals. The study was meant to correlate the…
At present, environmental sustainability is a big concern due to the limited resources and the adverse impacts of petroleum-based materials. Green composites (GCs) attracted intensive research interest for the last few decades from academicians,…
This study focuses on the post-recovery effect of Nigerian heavy crude viscosity in microbial enhanced oil recovery process. The technique involves the injection of exogenous hydrocarbon-degrading microbes with the required nutrients to guarantee the…
