Water Soluble Fraction of Crude Oil Uncouples Protease Biosynthesis and Activity in Hydrocarbonoclastic Bacteria; Implications for Natural Attenuation
Three hydrocarbonoclastic bacteria isolated from crude oil-impacted mesotidal waters of the Niger Delta area of Nigeria, and identified, by 16S rRNA sequencing, as Vibrio fluvialis OWPB63, SerratiaExpand
Kinetic modeling and quasi-economic analysis of fermentative glycolipopeptide biosurfactant production in a medium co-optimized by statistical and neural network approaches
Results showed that bio-catalytic rates of lipase and urease reached exponential values within the first 12 h of fermentation leading to high specific rates of substrate consumption and bacterial growth, suggesting that glycolipopeptide biosynthesis may proceed through stationary phase transpeptidation of the Glycolipid base.

Remediation of Oily Waste using Soil Organic Nutrient Stimulant
Aims: This present study aim at assessing the efficacy of soil-organic nutrient stimulant in the remediation of oily waste. Study design: Preparation of Soil-goat dung mix was used as stimulant forExpand
Comparative Analysis of Determination Methods of Glyphosate Degradation by Trichoderma asperellum Strain JK-28: A Multivariate Statistical Approach
Aims: This study aimed at demonstrating the ability of a mold species, isolated from a rice farm agricultural soil, chronically treated with glyphosate herbicide, to degrade glyphosate and to compareExpand
Statistical Distribution of Halotolerant/Halophilic Biosurfactant-Producing Yeasts in Qua Iboe Estuarine Sediments
We isolated 100 morphologically-distinct halotolerant/halophilic yeasts from five estuarine sediments in Qua Iboe estuary, South-South Nigeria. A three-way analysis of variance (ANOVA) of theExpand
Biodegradation potential of Aspergillus niger on crude oil contaminated soil.
The biodegradation potential of Aspergillus niger was investigated on soil experimentally contaminated with crude oil. The fungal load dynamics of Aspergillus niger and some chemical parameters ofExpand
Condition factor, hydrocarbons and bacterial burdens of shellfishes from mudflats in the Qua Iboe Estuary, Nigeria
It is shown that shellfishes from mudflats in the Qua Iboe Estuary are not healthy but have great capability to bioaccumulate hydrocarbons and bacteria. Expand
Influence of chemical speciation and divalent cations on cadmium toxicity during microbial biodegradation of crude oil
Microbial metal toxicity had been attributed to metal concentration and bioavailability, the later factor being dependent on speciation; the distribution of metals into various physicochemical forms.Expand


Microbial hydrocarbon degradation—bioremediation of oil spills
Bioremediation has become a major method employed in restoration of oil-polluted environments that makes use of natural microbial biodegradative activities. Bioremediation of petroleum pollutantsExpand
Effect of dispersed oil on heterotrophic bacterial communities in cold marine waters
The results show a detectable but transient response of the bacterial community to crude oil addition, and the structure of theacterial community in the less polluted tank appeared relatively unchanged after 14 days of contamination. Expand

L Laboratory and field biodegradation studies showed both quantitative and qualitative changes in the hydrocarbon content of crude oil due to microbial degradative activities and a faster rate of oil depletion from the Lagos lagoon during the rainy season. Expand
Distribution of hydrocarbon-utilizing bacteria in oil-spill areas
Les populations bacteriennes de differentes zones contaminees par du petrole au Nigeria ont ete etudiees en saison seche ou en saison humide. La presence de bacteries utilisant des hydrocarbures futExpand
