“…Strategies for inexpensive and clean in situ bioremediation include natural attenuation, biostimulation, bioventing, bioaugmentation, land farming, composting, and phytoremediation. These methods can be reviewed in numerous publications reporting on the bioremediation diesel oil (Richard and Vogel 1999;Olson et al 1999;Gallego et al 2001;Bento et al 2004;EL-Morsy 2005;EL-Morsy et al 2006) in soils.…”

Two naturally occurring fungal and bacterial species, Aspergillus flavus and Bacillus sp. H6 strains, were capable of utilizing diesel oil as a sole source of carbon in synthetic microcosoms. The initial diesel oil contamination of 1666 mg kg -1 dry soil was reduced to 166.667 mg kg -1 after 150 days of incubation in fungal-bacterial consortium microcosm. That is mean 89.9%, of the initial oil concentration was removed. Abiotic process reduced the diesel oil contamination to about 616 mg kg -1 dry soil at the end of the experiment. Seven microcosms were set up to fulfill the experiments. The decontamination activity follow this order; Bacillus sp. H6 + A. flavus consortium > Bacillus sp. H6 > natural control > A. flavus > cycloheximide treated > benzyl Penicillin-Streptomycin treated > poisoned control. Gas chromatographic analysis data revealed that both A. flavus and Bacillus sp. H6 treatment led to complete utilization of carbon-17 compounds. Other biodegradation products such as C-15, 16, 20, 21, and 24 appears in the chromatogram after 150 days incubation. Increase of C-20, 21 and C-24 compounds also noticed. The fungal-and bacterium consortium treatment depicted a decrease of all detected n-alkanes. The microbial success in biodegradation was evaluated by determining the number of germinating seeds of Phaseolus vulgaris. The highest level of germination (92 %) was detected in consortium microcosms after 150 days incubation. The treatment with A. flavus and Bacillus sp. H6 separately led to a lower percentage of germination (86%). The other treatments showed variable results except the poisoned control that showed negative germination and minor chemical degradation of diesel oil. Thus, bacterial-fungal consortium treatment is effective in bioremediation of contaminated oils than separate treatment.

“…If not properly disposed and managed the resulting environmental impact from these wastes can be disastrous [21]. Some of the obvious consequence of man-made pollution includes transmission of diseases by water borne pathogens, accumulation of toxic or recalcitrant chemicals in the soil, destabilization of ecological balance and negative effects on human health [7,14,20,24]. As a result of change in land use and accumulation of non-biodegradable wastes pointed out, there is need to determine the soil properties for proper management planning.…”

This study was conducted with a view to evaluating the physicochemical and mycological properties of different oil contaminated soils collected from three different automobile garages in Sokoto Metropolis, and uncontaminated soil from the temporary site, Usmanu Danfodiyo University, Sokoto (UDUS) was used as the control. The pH was determined using pH meter model Hanna (H1991301), quantity of mineral elements was evaluated in accordance with Murphy and Fungi were isolated from the three oil contaminated samples (A, B. and C) and the uncontaminated (sample D) as control, this was done by standard procedure using the method of P. Ren, T. Jankun & B. Leaderer. The physical, chemical, and mineral elements from the oilcontaminated soils of the three automobile garages and control. The results of particle soil analysis revealed the high content of sandy soil (96.2 to 87.3) and silt is the lowest with (2.5-0.6). Magnesium had the highest concentration of studied minerals, ranging from 193 to 649.2 mg/kg. while PH result revealed that the soil samples were pH value ranged from (16.85-16.20) in oil Contaminated samples, while the control had 15.90, and electrical conductivity ranged from 12.8-13.8 % and 28 % in control, four fungal isolates Aspergillus sp., Penicillum sp., Mucor sp. and Sporobolomyces sp. were identified based on colonial, sexual and morphological characteristics. These fungal strains can be used in bioremediation process and oil pollution reduction in aquatic ecosystems.

Some microorganisms are capable of biodegrading petroleum hydrocarbons [7,8]. Petroleum hydrocarbon utilizing microorganisms have recently been isolated in large numbers form a wide variety of natural aquatic and terrestrial environments.…”

Oil-polluted areas contain large amounts of poly-aromatic hydrocarbons (PAHs) which represent severe hazards on the ambient environment. Fungal strains were isolated from different contaminated sites in the Mediterranean coast and middle Delta, Egypt and screened for PAHs degradation. Hydrocarbon-enriched media was used to isolate the anthracene-, phenanthrene-and phenol-degrading fungi. Thirteen fungal isolates showed high degradation activities for anthracene, phenanthrene and phenol. One isolate was selected possessing high degradation ability and incubation period and was identified based on 18S rDNA sequence. Partial sequence of 18S rDNA revealed that this isolate is identified as Cunninghamella echinulata. Laccase enzyme produced by this fungus was subsequently evaluated for its degradative ability towards PAHs mixtures. The percentage of degradation varied from 96.035% to 99.986% of the tested PAHs. After an incubation period of 45 days, 5% of PAHs gave the highest degradation activity among all concentrations used. The kinetics of PAHs degradation is presented along with the feasibility of using Cunninghamella echinulata for bioremediation
