A suite of 10 dierent marine evaporitic oil samples from Sergipe-Alagoas Basin, Brazil was studied for its biomarker content, in particular its acidic constituents. The oils showed dierent molecular distributions and relative abundances of n-alkanoic, isoprenoid and hopanoic acids. The observed dierences were assigned to the incorporation of immature organic matter in the oils and fractionat...
Monoaromatic hydrocarbons such as benzene have been found in sludge created by oil production facilities and industries. Benzene is considered as a carcinogenic substrate and biodegradation, primarily under aerobic conditions, is an important environmental process for water and soil associated benzene remediation. Aerococcus sp. strain BPD-6 isolated from petroleum hydrocarbon contaminated oily...
The effects of process variables (temperature, space velocity, water addition and Si/Al ratio) on the conversion of acetone to aromatic chemicals have been investigated. The reaction is carried out by fixed bed reactor at an atmospheric pressure to examine the activity and selectivity of HZSM-5. The results show that HZSM-5 exhibited a high active and a shape-selective catalyst for the formatio...
Pseudomonas knackmussii B13 was the first strain to be isolated in 1974 that could degrade chlorinated aromatic hydrocarbons. This discovery was the prologue for subsequent characterization of numerous bacterial metabolic pathways, for genetic and biochemical studies, and which spurred ideas for pollutant bioremediation. In this study, we determined the complete genome sequence of B13 using nex...
