“…A wide varieties of microorganism resources have been found to be available for PAH degradation (Grishchenkov et al, 2000;Pan et al, 2004). Biochemical pathways for many lower-molecular-weight PAHs (LMW PAHs) and their biodegradation mechanisms have been clarified.…”

This paper reports on the investigation of concentration levels of PAHs, community structure, as well as the abundance of PAHrelated catabolic genes including upper-pathway dioxygenase genes (nahAc and phnAc) and down-pathway catechol dioxygenase genes (C12O and C23O) in a successive anoxic and aerobic treatment of produced water from the Jidong Oilfield, China. 93% of total PAHs were removed, almost equally contributed by the anoxic and aerobic units. However, PAHs of more than 3 benzene rings remained almost unchanged. The signals for phnAc and C12O were undetectable in this biological system, whereas the existence of nahAc and C23O was confirmed in the system and the copies of the two genes in the aerobic tank were 2 or 3 orders higher than those in the influent water sample. The different behavior of C23O demonstrated that mineralization of PAHs might mainly occur in the aerobic unit. The existence of nahAc and C23O genes in the influent and the high similarity of genotype between the influent and the two sludge samples suggested that bacteria existing in the influent contributed to PAH removal and bacteria harboring PAH catabolic genes were enriched in the sludge.

“…The use of pure cultures (bacteria, yeasts or filamentous fungi) and mixed cultures for the decontamination of sites contaminated with petroleum and petroleum derivatives is often a promising technological solution, which significantly reduces or eliminates the pollution load that may be present in the soil or in liquid media (Bielecka et al, 2002;Díaz et al, 2000;Lakha et al, 2005;Townsend et al, 2004;Gogoi et al, 2003;Grishchenkov et al, 2000). The activated sludge process is one of the most widely used technologies for biological treatment of wastewater.…”

-This study evaluated the effects of aeration (constant aeration, intermittent aeration and a lack of aeration) and hydraulic retention time (HRT) (2, 3 and 4 days) on a continuous process with cell recycling, using chitosan as a natural coagulant for the sedimentation of a C 1 mixed culture. This culture was used for the biodegradation of hydrocarbons present in the effluent contaminated with diesel oil and gasoline. The responses monitored included the turbidity removal (TR), total petroleum hydrocarbon (TPH) removal and volatile suspended solids (VSS). Constant aeration and an HRT of 4 days produced the best results for the continuous process, resulting in the highest TPH removals (94% and 75% reductions in the supernatant and reaction tank, respectively) and TR (95%).

Although a number of microorganisms have utilized alternate electron acceptors such as nitrate, manganese (IV), iron (III), sulfate and carbon dioxide (Heider et al, 1999;Grishchenkov et al, 2000;Boopathy, 2002;Massias et al, 2003).The DCPIP technique is a rapid, simple and low cost procedure for evaluating capability of different microorganisms to degrade different oil (Mariano et al, 2008).…”

<div> Petroleum products are used in different forms in auto-mechanic workshops every day. Spent motor oil disposed-off improperly contains potentially toxic substances which can seep into the water tables and contaminate ground water. This study involved isolation and screening of bacterial species capable of utilizing hydrocarbons from three auto-mechanic workshops in Abeokuta, Ogun State. Total Heterotrophic Bacterial Counts ranged from 1.03 × 106 to 2.81 × 106 CFU/g. Total Oil Degrading Bacterial Counts varied between 4.0 × 105 and 2.01 × 106 CFU/g while Surface Active Bacterial Counts were from 1.2 × 104 to 2.76 × 105 CFU/g. Twenty-four bacteria species capable of utilizing petroleum as a carbon source were isolated from various contaminated soils using enrichment technique. Isolated bacteria include: Bacillus spp., Pseudomonas aeruginosa, Micrococcus spp., Proteus mirabilis, Proteus vulgaris and Enterobacter spp. Redox indicator 2, 6-dichlorophenol indophenol (DCPIP) was used to screen for efficient hydrocarbon (Kerosene, Premium Motor Spirit, and Engine oil) degradation by bacteria. Degradation efficiency was measured by optical density at 600 nm. Micrococcus spp., Proteus mirabilis, and Pseudomonas aeruginosa were found to be the best isolates growing on majority of hydrocarbons due to their high utilization value when growing on the hydrocarbons tested. </div>
