“…Enzyme induction during the degradation of crude oil depends on the crude oil composition and their metabolic products. Therefore, Hollaway et al (1980) supported the views that consortia with broad pH pH of soil used in this study was found to be slightly basic in nature, but addition of NPK and bulking agents decreased the soil pH to different extents. A maximum decline in soil pH (6.12) was recorded in the presence of sugarcane bagasse in SC6, possibly due to more acidic nature of sugarcane bagasse, when compared to other bulking agents.…”

Different bacterial and fungal strains, isolated from petroleum hydrocarbon-contaminated soil, were tested, in isolation as well as in combination, for their ability to degrade total petroleum hydrocarbon (TPH) in soil samples spiked with crude oil (2, 5 or 10 %, w/w) for 30 days. The selected combination of bacterial and fungal isolates, i.e., Pseudomonas stutzeri BP10 and Aspergillus niger PS9, exhibited the highest efficiency of TPH degradation (46.7 %) in soil spiked with 2 % crude oil under control condition. Further, when this combination was applied under natural condition in soil spiked with 2 % (w/w) crude oil along with inorganic fertilizers (NPK) and different bulking agents such as rice husk, sugarcane, vermicompost or coconut coir, the percent degradation of TPH was found to be maximum (82.3 %) due to the presence of inorganic fertilizers and rice husk as bulking agent. Further, results showed that the presence of NPK and bulking agents induced the activity of degradative enzymes, such as catalase (0.718 m mol H 2 O 2 g -1 ), laccase (0.77 lmol g -1 ), dehydrogenase (37.5 lg g -1 h -1 ), catechol 1, 2 dioxygenase (276.11 l mol g -1 ) and catechol 2, 3 dioxygenase (15.15 l mol g -1 ) as compared to control (without bioaugmentation). It was inferred that the selected combination microbes along with biostimulants could accentuate the crude oil degradation as evident from the biostimulantinduced enhanced activity of degradative enzymes.

“…Atlas (1988) reported that the population of any aquatic system is to a large extent influenced by the water body. Establishing the presence of bacteria in water bodies is important, as they have been identified as the major organisms which initiate the breakdown of introduced wastes including hydrocarbons to various metabolic intermediates (Hollaway et al, 1980). TBC and TCC were high with the TBC being higher during the study.…”

Northern Nigeria represents the most populous region in Nigeria and adequate water supply and sanitation typically leaves a lot to be desired in the region in order to prevent water related diseases to the vulnerable communities of the region. This research work was carried out in Kano state with specific emphasis on Tomas dam which is one of the largest dams established for multipurpose use in Nigeria. The research was aimed at evaluating Physico-chemical and Bacteriological quality of Tomas Dam in Kano State. 240 water samples from 5 sampling stations within eight months were analyzed for bacteriological and physico-chemical quality. The physico-chemical parameters indicated Biochemical Oxygen Demand (BOD) and Water Current Speed results were not significantly different (P>0.05), while other physico-chemical parameters analyzed varied significantly (P<0.05). The study also revealed that Dissolved Oxygen (DO), BOD, Turbidity, and Nitrates recorded higher values than WHO and Federal Environmental Protection Agency, Nigeria (FEPA) limits. Total aerobic bacterial counts (TBC) and total coliform counts (TCC) were determined using pour plate and Most Probable Number (MPN) techniques. TBC and TCC were high and exceeded acceptable limits. Faecal coliforms, faecal Streptococciand Klebsiella species constituted 25% of the indicator organisms identified.The observed parameters indicated the Dam was contaminated with pathogenic bacteria. Variations in the weather conditions, animal and anthropogenic interferences were all directly or indirectly related to faecal contamination in the dam. Preventing indiscriminate faecal discharge close to the Dam and sufficient water treatment before consumption are of prime importance to public health as the dam was established for agricultural purposes.

“…Though members of the domain Archaea are known to thrive in oilfield ecosystems Stetter et al, 1993), it now appears that fermentative bacteria could be the dominant microbial community in these ecosystems (Davydova-Charakhch'yan et al, 1993;Fardeau et al, 1993Fardeau et al, , 1996Holloway et al, 1980;Jeanthon et al, 1995;L'Haridon et al, 1995;Ravot et al, 1995a;Stetter et al, 1993). We recently isolated from oilfields fermentative bacteria that have the ability to reduce thiosulfate to sulfide during growth on organic compounds (Fardeau et al, 1993;Magot et al, 1997a, b;Ravot et al, 1995aRavot et al, , b, 1997.…”
