This study investigates the concentrations of total petroleum hydrocarbon (TPH) and content (THC) in soil samples from auto-mobile mechanic workshop Ikot Akpaden, Mkpat Enin. Soil were collected triplicate at different points within vicinity Akpaden represented as site A control obtained frontage Chemistry Department, AKSU C. Soxhlet extraction shaking methods used for hydrocarbons respectively...

Soil structure is an important key in the bioremediation process; for instance, clay soils tend to have high absorption of pollutants and low rates due their plasticity oxygen restrictions. This work assesses seven different treatments contaminated soil using lime, silica nanoparticles, both components combination. After a three-month treatment, variation granulometry, pH, porosity, cation exch...

BACKGROUND Patents have been granted for a number of techniques for petroleum biodegradation including use of micro-organisms for degradation of hydrocarbon-based substances and for hydrocarbon degradation in oil reservoirs, but there is a dearth of information on hydrocarbon degradation in different soil textures. OBJECTIVE Hence, this work investigated the effects of different soil textures...

Heavy hydrocarbons (HHCs) in soils impacted by crude oil spills are generally recalcitrant to biodegradation due to their low bioavailability and complex chemical structure. In this study, soils were pretreated with varying concentrations of ultraviolet radiation A (UVA) or ultraviolet radiation C (UVC) activated titanium dioxide (TiO2) (1%–5%) under varying moisture conditions (0%– 300% water ...

A novel bacterial strain was isolated from industrially contaminated waste water. In the presence of crude oil, this shown to reduce rate total petroleum hydrocarbons (TPH) up 97.10% in 24 h. This bacterium subsequently identified by 16S rRNA gene sequence analysis and affiliated Serratia genus RDP classifier. Its genome sequenced annotated, genes coding for catechol 1,2 dioxygenase naphthalene...

Surface sediments collected from 2001 to 2011 were analyzed for total petroleum hydrocarbons (TPH) and five heavy metals. The sediment concentration ranges of TPH, Zn, Cu, Pb, Cd and Hg were 6.3-535 μg/g, 58-332 μg/g, 7.2-63 μg/g, 4.3-138 μg/g, 0-0.98μg/g, and 0.10-0.68 μg/g, respectively. These results met the highest marine sediment quality standards in China, indicating that the sediment was...

The present paper describes the process optimization study for crude oil degradation which is a continuation of our earlier work on hydrocarbon degradation study of the isolate Stenotrophomonas rhizophila (PM-1) with GenBank accession number KX082814. Response Surface Methodology with Box-Behnken Design was used to optimize the process wherein temperature, pH, salinity, and inoculum size (at th...

so far, different methods have been applied to clean up soils contaminated with oil. bioremediation is one of the clean up technologies which uses microorganisms or microbial processes to degrade oil contaminations in soils. this study evaluates the applicability of cow manure as bioremediation alternative for soils spiked with petroleum hydrocarbons. target contaminant of this research was die...
