Bioremediation of crude oil pollution in the Kuwaiti desert: The role of adherent microorganisms

Population dynamics and distribution of hydrocarbon utilizing bacteria in Automobile workshops within Uyo metropolis, Akwa Ibom State

“…This comparatively high tolerance of Bacillus species to hydrocarbon may be attributed to their possession of resistant endospores and/or plasmids thus, suggesting their efficiency in the clean-up of hydrocarbon polluted sites (Ghazali et al, 2004). Besides, the biodegradation potential of Bacillus species isolated from soils have been reported to be far higher than other bacterial isolates (Del' Arco and de Franca, 2001;Obuekwe and Al Zarban, 1998). This trend was also observed in Bacillus sp isolated from crude oil polluted soils in Nigeria (Ilori and Amund, 2000).…”

Application of statistical experimental methodology to optimize bioremediation of n-alkanes in aquatic environment

“…Higher n-alkanes C12-C21, C22-C31 and C32-C40 were removed at the levels of 83-98%, 80-85% and 57-73%, respectively. Obuekwe and Al-Zarban [30] removed C22, C24 and C26 in soil up to 99.3%, 98.7% and 91.7% respectively.…”

Isolation and Identification of Petrol Degrading Microorganisms From Contaminated Soil and Comparison of Their Bioremediation Potential

“…Log phase cultures were inoculated to 100 mL of sterile mineral salts medium with 0.2% v/v petrol, in duplicate, with uninoculated media consituting as control. 17 All flasks were incubated at 22 0 C for time intervals of 7, 14, 21, 28 and 35 days. The content of each flask was taken at the end of the determined incubation period to assess residual concentrations of crude oil by gravimetric analysis.…”
