“…Linda, et al, (2016) and German, et al, (2016) reported the degradation ability of Klebsiella sp. The degrading high ability of Pseudomonas sp in this study follows the same trend with the reports of Das and Mukhereree, (2007), Ezeji et al, (2005). However there was a significant difference in the weight of crude oil degraded at (p<0.05).…”

“…The highest oil utilization was observed in Pseudomonas sp (77.5%), this was followed by Bacillus sp (66.8%) and Klebsiellasp (54.2%). Genus Pseudomonas has been implicated by many investigators to be a potent hydrocarbon utilizer (Udotong, 1995, Essien et al, 1997and Ezeji et al, 2005. The high degrading ability o f Pseudomonas sp recorded in this study is however not uncommon and is consistent with other reports.…”

The ability of some bacterial isolates to utilize crude oil and the effects of pH and various nitrogen sources on the growth and utilization of hydrocarbons were investigated. A total of six bacterial isolates were isolated. These include two different species of Bacilli, three different species of Pseudomonas and Klebsiella species. The effects of pH on the growth of the isolates showed that Pseudomonas sp (A2) had the highest growth of about 2.25×10 5 cfu/ml at pH 6.5. Baciliussp (A5), Klebsiellasp (A1) recorded growths of 2.04×10 5 and 1.70×10 5 cfu/ml at pH 7.5 and 7.0 respectively. These isolates were able to utilize and grow on different nitrogen sources containing ammonium sulphate((NH 4) 2 SO 4), sodium nitrate (NaNO 3), and ammonium chloride (NH 4 Cl). NH 4 Cl was the best utilized nitrogen source with growth of 2.37×10 5 , 2.17×10 5 , and 1.93×10 5 cfu/ml for Pseudomonas, Bacillus and Klebsiella species respectively. The effects of pH on the utilization of Bonny light crude oil revealed percentage utilization of about 76%, 68%, and 58% at pH of 6.5, 7.5 and 7.0 respectively for Pseudomonas, Bacillus and Klebsiella species. Percentage utilization of about 67%, 63%, and 51.8% were recorded for Pseudomonas, Bacillus and Klebsiella species when grown on mineral salt media supplemented with NH 4 Cl. The isolates were tested for their ability to utilize bonny light crude oil using the gravimetric method. The percentage utilization of all the isolates ranged between 77.5%, 66.8%, and 54.2% after 28 days of incubation for Pseudomonas, Bacillus and Klebsiella species respectively.

“…However, the presence of crude oil in the environment creates a niche for specially adapted indigenous petroleum-degrading microorganisms well represented in the soil and water environments. These organisms include bacteria of the genera; Arthrobacter, Pseudomonas, Acinetobacter, Bacillus etc., while fungi such as Candida, Rhodotorula, Mortierella, Aspergillus as well as algae-Protothecazopfi, cyanobacteria, green and red alga (Ijah et al, 2008;Ezeji et al, 2005).…”

“…Microbial degradation process aids the elimination of spilled oil from the environment after critical removal of large amounts of the oil by various physical and chemical methods (Ijah and Okang, 1993). This is possible because microorganisms have enzyme systems to degrade and utilize diesel oil as a source of carbon and energy (Ijah and Antai, 1988;Ezeji et al, 2005;Antai and Mgbomo, 1993). This study was designed to isolate, characterize and identify diesel oil-degrading microorganisms.…”

Diesel oil, left standing in a laboratory for six months, was used as source for the isolation of Bacillus subtilis, Bacillus cereus, Trichoderma harzanium and Trichothercium roseum. These organisms were found to be hydrocarbon degraders. On further testing, it was found that B. subtilis had higher potential to utilize diesel oil as carbon source. Soil samples were polluted with diesel oil at a loading rate of 5% (v/w) (oil/soil). These soil samples, together with the unpolluted control samples, were seeded with the B. subtilis isolate. The degradation of the diesel oil was monitored over a twenty-seven-day period, using gravimetric method. The rates of degradation of diesel oil by the isolate at the end of day one, day twelve and day twenty-seven were 5.8 x 10-4 , 1.83 x 10-3 and 1.05 x 10-3 g/h, respectively.
