“…It is comprised of a very large family of several hundred chemical compounds [1,2]. Petroleum hydrocarbons are of environmental interest because they are toxic to the human system, plants and animal resources [3,4].…”

“…Yet, they pervade the environment beyond the vicinities of petroleum exploration and production activities due to storage, disposal and other handling activities during which contamination of the environment sometimes occur. Toxicity effects of total petroleum hydrocarbons in different environmental media have been studied [3][4][5]. The concentrations of total petroleum hydrocarbons recorded in an aged crude oil-contaminated soil in Yorla, Ogoniland have been reported [6] to be above the Department of Petroleum Resources (DPR)/Environmental Guidelines and Standards for the Petroleum Industries in Nigeria (EGASPIN) intervention limit of 5000 mg/kg [7].…”

Post-remediation assessment of residual total petroleum hydrocarbon (TPH) in an aged crude oil-contaminated soil (ACOCS) in Ogoni after seventy-day enhanced remediation by bio stimulation was investigated using gas chromatographic fingerprinting (GCF) technique and phytotoxicity bioassay. Seven treatments were designed and composted water hyacinth (EC), Mexican sunflower (TD) and Bermuda grass (CD) was applied as bio stimulants. Composted EC, TD or CD (2,500 g) was incorporated singly and in various combinations into 4,000g of ACOCS in situ. Soil treatments consisted of TPA (un-amended), TPB (amended with EC), TPC (amended with TD), and TPD (amended with CD). Others include TPE (amended with EC and TD), TPF (amended with EC and CD) and TPG (amended with EC, TD and CD). There was significant (ρ >0.05) reduction in total petroleum hydrocarbon (TPH) in TPG from 93,867 to 1,002 ppm when compared to TPA which had TPH reduced from 98,673 to 79,583ppm. Gas chromatographic fingerprints of ACOCS before treatment indicated absence of n-alkanes within n-C 2 to n-C 8 region which was attributed to weathering processes. However, after treatment with the substrates, carbon lengths n-C 9 to n-C 34 were significantly (ρ >0.05) attenuated while those from n-C 35 to n-C 45 showed a decreasing tendency for enhanced attenuation thus, signifying their possible immobilization in particle pores. Seed germination index was ≥ 65%, indicating that the remediated soil is non-phytotoxic and could support plant growth.

“…As shown in Table 2, TPH concentration in soils has decreased as the depth increased that might be affected by low soil permeability [Iwegbue et al 2003]. Low permeability of soil was an advantage, as crude oil has low potential migration and risk of groundwater contaminated [O'Reilly et al 2001].…”

This study was aimed at isolating and characterizing hydrocarbon-degrading fungi from hydrocarbon-contaminated soil in Ogbe-Ijoh oil creek in Warri, Delta State, Nigeria. Isolation and characterization were carried out using standard methods. Biodegradation assay was carried out over 25 days and monitored using the following parameters; pH, total organic carbon, and total hydrocarbon content. The fungi isolated were: Penicillium sp., Aspergillus niger and Fusarium sp., and these were used for the biodegradation study. Physico-chemical analysis of the crude oil contaminated soil during degradation showed that there was significant decrease in pH during degradation from day 10 - 25 (p ≥ 0.05). This showed the ability of the fungal isolates to utilize crude oil as carbon source, producing acid during its metabolism. The highest pH value during degradation by the fungal isolates was recorded in Fusarium sp. and the lowest was recorded in Aspergillus sp. The fungal isolates were able to reduce the total carbon and hydrocarbon content during degradation. This was probably due to the utilization of the nutrients in the soil sample as energy source. The results from this study indicate the potential of the isolated fungi for hydrocarbon bioremediation activity.
