“…Polycyclic aromatic hydrocarbons (PAHs), produced by incomplete combustion of fossil fuels, and also manufactured for use in the pesticide, pharmaceutical and dyemaking industry are ubiquitous and persistent in the environment (Mueller et al, 1996;Clemente et al, 2001;Garon et al, 2004). They are hydrophobic and can readily bio-accumulate in the environment.…”

The study investigated the degradation of the polycyclic aromatic hydrocarbons (PAH) benzo(a)anthracene, benzo(a) fluoranthene, benzo(a) pyrene, chrysene and phenanthrene in a soil that was sterilized and inoculated with the nonligninolytic fungi, Fusarium flocciferum and Trichoderma spp. and the ligninolytic fungi, Trametes versicolor and Pleurotus ostreatus in the presence of cadmium (Cd) and nickel (Ni) during a ten week incubation period. The soil pH was initially 5.3 and after amendment increased to 7.0. The fungi degraded the tested PAHs between 21 and 93% by the end of the tenth week. The fungi degraded the less-soluble PAHs containing five or six aromatic rings more slowly than those containing fewer aromatic rings. Although the presence of cadmium and nickel in the soil affected the activity of the enzymes produced by the fungi, no significant decrease in PAH degradation was found in the contaminated soil containing 50 or 100 mg kg -1 of Cd and Ni. However, at 300 and 500 mg kg -1 , degradation of the PAHs by the fungi was impaired and the severity of the impairments increased with the increase in the concentrations of Cd and Ni. This was probably due to the lack of the activities of some enzymes such as Mn-dependent peroxidase, which could have resulted from the poor colonization of the fungi at these concentrations.

“…Hydrocarbon contamination of the air, soil, fresh water especially by polycyclic aromatic hydrocarbon (PAHs) attracts public attention because many PAHs are toxic, mutagenic, and carcinogenic (Clemente et al, 2001). Prolong exposure of high oil concentration may cause the development of liver or kidney diseases, possible damage to the bone marrow and increased risk of cancer (Mishra et al, 2001;Lloyd and Cackette, 2011).…”

This study investigates the hydrocarbon degradation potentials of some bacteria isolated from spent lubrication oil on contaminated soil. Cleaning up petroleum hydrocarbon contaminated sites has been a major challenge. This has led to the exploration of many approaches to affect the cleanup of the polluted soils. A total of sixteen hydrocarbon degrading bacteria species were isolated from spent lubricating oil contaminated soil. The predominant species belonged to the genera Pseudomonas and Enterobacter. Three strains namely Nocardia sp., Pseudomonas sp and Bacillus sp showed the highest potential for hydrocarbon utilization. Their ability to degrade both the aliphatic (n-alkanes) and Polyaromatic Hydrocarbon (PAH) components of the spent lubricating oil in MSM was investigated after 21days of biodegradation studies using gas chromatographic (GC) techniques. Over 98% of the n-alkane and PAHs fraction of the spent lubricating oil supplied at 1.0%vv -1 concentration were degraded by the three strains. Nocardia sp showed the highest percentage of degradation of about 99%. This study has shown that resident bacteria strains in lubricating oil contaminated soils have potential application in the bioremediation of oil polluted sites and enhance the possibility of developing models and strategies for removing hydrocarbon pollutants from the environment. © JASEM https://dx.doi.org/10.4314/jasem.v21i5.26

“…Degradation and decolorization of many organic pollutants by white-rot fungi have been reported by many researchers [20], but MnP and LiP are noted mainly for the degradation of polymeric dyes [21]. The white rot fungi have the ability to decolorize polymeric dyes because of existing ligninolytic enzymes.…”

The potential of ligninases as a green tool for effective valorization of lignin can be shown through enzymatic cocktails containing different lignin degrading enzymes. The present study deals with the screening of potential fungal strains useful for the liquefaction of bark containing lignin. Three different local isolates (Pleurotus ostreatus POS97/14, Pycnoporus sanguineus and the local isolated fungal strain) were selected out of ten different strains for ligninases production. Maximum production of enzymes was observed in the local isolated fungal strain after ten days in submerged fermentation.The isolated fungal strain produces ligninases mainly for manganese peroxidase (MnP). The enzyme oxidized a variety of the usual MnP substrates, including lignin related phenols. Furthermore, the partial purification for MnP was determined by FPLC and the molecular weight was evaluated by SDS-PAGE.
