“…Metabolism of the branched alkanes, pristane, and phytane was presumably slower. These results are in agreement with results obtained by many investigators (Diaz et al 2002;Gouda et al 2007). Ratios of nC17/pristane and nC18/phytane were relatively similar in EXPS and CSS1.…”

Soil artificially contaminated with diesel oil, treated with cassava steep liquor (CSL) and designated EXPS. Similar polluted soil without CSL amendment (CSS1) and uncontaminated soil (CSS2) served as controls. There were dramatic changes in the physico-chemistry of systems EXPS and CSS1 with utilization of the inorganic nutrients to near-depletion in the former than the latter. In contrast, the properties of CSS2 remained relatively stable throughout the investigated period. Similarly, the population densities of microflora in the polluted soils showed an initial decrease between days 0 and 5 before assuming an increasing trend with percent hydrocarbon-utilizers ranging significantly (P \ 0.05) from 0.56 to 6.6, 0.1 to 2.46 and 0.56 to 0.26, respectively for EXPS, CSS1, and CSS2. In EXPS, the residual oil decreased from 98,045 to 1,102.3 mg/kg soil at day 35 representing about 98.88% degradation. The corresponding value for CSS1 was 98,106.1 to 52,110 mg/kg soil, amounting to 46.88% oil disappearance. The GC fingerprints of alkane fractions of the recovered oil reduced significantly by day 15 for EXPS with near-similar results of CSS1. However, by day 35, there was complete disappearance of all peaks including the pristane and phytane molecules in the former whereas in CSS1, there were no observable changes. The germination and growth profiles of maize seed plants as evidence of recovery of oil-impacted soils were poor in CSS1 (10%) with pronounced abnormal morphology when compared with the data obtained for EXPS (74%) and CSS2 (80%). These results suggest that CSL could be an indispensable tool in bioremediation of environments contaminated with hydrocarbons. The technology of application is simple, rapid and cost-effective and may be appropriate for use in developing countries to ameliorate the problems of petroleum pollution.

“…Chromatographic analysis showed that the n-alkanes fraction are easily metabolised in comparison with aromatic fractions. The same results were obtained by Gouda and co-workers [24]. Oh and co-workers [23] demonstrated that short chain n-alkanes are rapidly degraded whereas long chain n-alkanes are slowly degraded.…”

“…Bacteria, yeast, and filamentous fungi have been reported as transforming agents due to their ability to degrade a wide range of pollutants (Wongsa et al, 2004;Gouda et al, 2007;Saratale et al, 2007;Laila and Nour, 2008). Although hydrocarbon degraders may be expected to be readily isolated from a petroleum oil-associated environment, the same degree of expectation may be anticipated for microorganisms isolated from a totally unrelated environment (Ojo, 2005).…”

“…Although hydrocarbon degraders may be expected to be readily isolated from a petroleum oil-associated environment, the same degree of expectation may be anticipated for microorganisms isolated from a totally unrelated environment (Ojo, 2005). Information on the fungal degradation of a defined single hydrocarbon is available in the literature (Sugiura et al, 1997), but less is known about the biodegradability of commercial petroleum products such as kerosene and diesel (Gouda et al, 2007). In addition, Shamiyan et al (2013a;2013b) stated that fungal isolates from aged petroleum-product-contaminated sites were capable of degrading commercial petroleum products utilizing them as sole carbon sources.…”

The current study suggests that the fungal isolates P. decumbens PDX7, P. janthinellum SDX7, and A. terreus PKX4 degraded kerosene by 95%, 96%, and 75% and diesel by 79%, 75%, and 70% after 16 days based on the ability of utilizing these compounds as sole carbon sources. GC-MS chromatograms revealed that n-alkane fractions are easily degraded; however, the rate is lower for branched alkanes, n-alkyl aromatics, cyclic alkanes, and polynuclear aromatics displaying delayed and lower degradation. The ratio of aromatic/aliphatic hydrocarbons >0.8 indicates the efficiency of these fungi in removing the aromatic hydrocarbons of the petroleum products. All of the treated fungal strains exhibited higher MnP, laccase, and dehydrogenase activities on the twelfth and sixteenth days as compared to the initial fourth and eighth days. In addition, P. decumbens PDX7 and P. janthinellum SDX7 displayed higher enzymatic activities as compared to A. terreus PKX4. Fungal isolates were also tested for their growth on various xenobiotic compounds as sole carbon sources.
