Degradability of n-hexadecane by Bacillus cereus DQ01 isolated from oil contaminated soil from Daqing oil field, China
Localisation of degradation enzyme in Bacillus cereus DQ01 for n-hexadecane, production and characteristics of n-hexadecane-degrading enzyme were studied in this paper. The cellular extracts of Bacillus cereus DQ01 were fractionated into extra-cellular, periplasmic and cytoplasmic fractions after osmotic shock. The results showed that cytoplasmic and periplasmic enzymes are mainly responsible for ...

Evaluation of The Efficiency of Various Commercial Products for The Bioremediation of Hydrocarbon Contaminated Soil
Bioremediation has become an important method for the treatment of terrestrial oil spills and is often favoured over strictly physical-chemical methods. In this study, enzymatic analyses and signature lipid biomarkers were employed to evaluate the efficacy of selected bioremediation products on control and oil contaminated soil plots. It is envisioned that these biological indicators may be used ...

Environmental and health risk assessment of an oil contaminated site in the Mexican tropical southeast
The aim of the present study was the environmental and health risk assessment of the oil contaminated soil in the Mexican tropic. The case is based on the total petroleum hydrocarbons (TPH) and polycyclic aromatic (PAH) soil contamination resulting from the activities of the oil industry over 70 years. The results of this study were estimated using CalTOX, a multimedia exposure model. The ...
