Rehabilitation of polluted soils with petroleum products requires a re-vegetation strategy to obtain a green mass cover that can quickly and efficiently cover the polluted soil. For the gradual recovery of the destroyed soil, it was necessary: 1. adequate soil treatments with fertilizer i.e. sewage sludge and fly ash as amendment, 2. plant species selection, 3. agronomical works in accordance with geographical position and climatic conditions. Fertilizers and fly ash create conditions for plant installation, by nutrients insurance. Our experiment was conducted in pots with 91.73�11.12 [gKg-1 D.M (dry matter)] total petroleum hydrocarbons (TPH) polluted soil, fertilised with sewage sludge and fly ash 60 [tha-1] derived from the burning of fossil fuels in thermal power plants. The selected plant species for bio-remediation is Lolium perenne. The selected plant species Lolium perenne is installed on 50-90% of the land surface giving 8 successive crops of grass in the warm season. The TPH reductions of polluted and treated soil were 38.4-56.3 [%]. The biomass did not bioaccumulate chromium at the detection limit. The amounts of cadmium, lead and zink bioaccumulated in the aerial parts were below acceptable limits. The obtained biomass can be used as animal feed or for bedding in shelters. The soil remediation efficiencies of 91.73 � 11.12 [gKg-1 D.M] were directly proportional to the amount of fly ash used.

To date, many developing countries such as Iran have almost completely abandoned the idea of decontaminating oil-polluted soils due to the high costs of conventional (physical/chemical) soil remediation methods. Phytoremediation is an emerging green technology that can become a promising solution to the problem of decontaminating hydrocarbon-polluted soils. Screening the capacity of native tolerant plant species to grow on aged, petroleum hydrocarbon-contaminated soils is a key factor for successful phytoremediation. This study investigated the effect of hydrocarbon pollution with an initial concentration of 40 000 ppm on growth characteristics of sorghum (Sorghum bicolor) and common flax (Linum usitatissumum). At the end of the experiment, soil samples in which plant species had grown well were analyzed for total petroleum hydrocarbons (TPHs) removal by GC-FID. Common flax was used for the first time in the history of phytoremediation of oil-contaminated soil. Both species showed promising remediation efficiency in highly contaminated soil; however, petroleum hydrocarbon contamination reduced the growth of the surveyed plants significantly. Sorghum and common flax reduced TPHs concentration by 9500 and 18500 mg kg‑1, respectively, compared with the control treatment.

The exploitation of petroleum has generated various sources of pollution in soil. In order to resolve this problem, several techniques have been developed. Physical and chemical methods are the most widely methods used for land treatment of oil polluted soils. These methods are expensive, ineffective and could cause a lot of damages on soil. The biological methods are not expensive and do not cause changes in the soil physical and chemical characteristics. Bioremediation is based on the capacity of microorganisms to degrade organic pollutant compounds, such as hydrocarbons. This study presents the preliminary results of a bioremediation alternative for soils polluted with crude oil (petroleum hydrocarbons). The bioremediation was achieved by increasing the microbial population by adding the fibers provided from celluloid wastes and bacteria inoculum. The paper presents the effect of a bioremediation treatment applied to a cambic chernozem polluted with 50000 mg kg-1 (5% crude oil) and 100000 mg kg-1 (10% crude oil) of a complex mixture of total petroleum hydrocarbons (TPH).

Crude oil bioremediation of soils is limited by the bacteria activity in degrading the spills hydrocarbons. The aim of this study is to enhance the bioremediation of soils polluted with crude oil by adding the natural biodegradable product and bacterial inoculum. Biodegradation was quantified by total petroleum hydrocarbons (TPH) analyses. Petroleum hydrocarbon pollution is one of the main environmental problems, not only by the important amounts released but also because of their toxicity. The main objective of this work is to accelerate the biodegradation processes. The enhancement of petroleum hydrocarbons degradation was achieved under natural product treatment and bacterial inoculum. The bacterial inoculum was used to enrich indigenous microbes to enhance biodegradation rate in the green house experiment.

The present study investigated the viability of purple nutsedge in the phytoremediation of a crude oilcontaminated land in the Kom-Kom community, Oyigbo, Rivers state, Nigeria. 150g of soil samples were randomly collected from two (2) different points on the polluted site and a control site and analyzed for Petroleum Aromatic Hydrocarbons (PAHs), Total Petroleum Hydrocarbons (TPH) and Heavy metals ( Pb, Cd, Cr & Ni). in soils and plants before and after phytoremediation. Plants were transplanted into the contaminated and contaminated soil after soil sample collection.After planting,the progress of plant growth was observed and recorded biweekly for 3 months before harvesting. From the results obtained, over 80% and 66% PAHs and TPHs phytodegradation efficiencies were achieved using the plant while Cd, Pb and Cr were removed by 90%, 67% and 39.2% respectively. The Bioaccumulation Factor (B.F) of the heavymetals in study plant were found to be greated than 1 which makes it suitable for phytoextraction of heavy metals. Therefore, the study suggests that purple nutsedge can be useful in the phytoremediation of a crudeoil polluted soil.

Endophyte-enhanced phytodegradation is a promising technology to clean up polluted soils. To improve the success rate of this nature-based remediation approach, it is important to advance the inoculation method as this has been shown to strongly affect the final outcome. However, studies evaluating inoculation strategies and their effect on hydrocarbon degradation are limited. This study aims to investigate two different manners of endophyte inoculation in Lolium perenne growing in an aged petroleum hydrocarbon polluted soil: (1) direct soil inoculation (SI), and (2) pre-inoculation of the caryopses followed by soil inoculation (PI). Different endophytic bacterial strains, Rhodococcus erythropolis 5WK and Rhizobium sp. 10WK, were applied individually as well as in combination. Depending on the method of inoculation, the petroleum hydrocarbon (PHC) degradation potential was significantly different. The highest PHC removal was achieved after pre-inoculation of ryegrass caryopses with a consortium of both bacterial strains. Moreover, both strains established in the aged-polluted soil and could also colonize the roots and shoots of L. perenne. Importantly, used endophytes showed the selective colonization of the environment compartments. Our findings show that the method of inoculation determines the efficiency of the phytodegradation process, especially the rate of PHC degradation. This study provides valuable information for choosing the most cost-effective and beneficial means to optimize phytodegradation.

A Ciboria sp. strain (Phylum Ascomycota) was isolated from hydrocarbon-polluted soil of an abandoned oil refinery in Italy. The strain was able to utilize diesel oil as a sole carbon source for growth. Laboratory-scale experiments were designed to evaluate the use of this fungal strain for treatment of the polluted soil. The concentration of total petroleum hydrocarbons (TPH) in the soil was 8,538 mg/kg. Mesocosms containing the contaminated soil were inoculated with the fungal strain at 1 or 7%, on a fresh weight base ratio. After 90 days of incubation, the depletion of TPH contamination was of 78% with the 1% inoculant, and 99% with the 7% inoculant. 16S rDNA and ITS metabarcoding of the bacterial and fungal communities was performed in order to evaluate the potential synergism between fungi and bacteria in the bioremediation process. The functional metagenomic prediction indicated Arthrobacter, Dietzia, Brachybacerium, Brevibacterium, Gordonia, Leucobacter, Lysobacter, and Agrobacterium spp. as generalist saprophytes, essential for the onset of hydrocarbonoclastic specialist bacterial species, identified as Streptomyces, Nocardoides, Pseudonocardia, Solirubrobacter, Parvibaculum, Rhodanobacter, Luteiomonas, Planomicrobium, and Bacillus spp., involved in the TPH depletion. The fungal metabolism accelerated the onset of specialist over generalist bacteria. The capacity of the Ciboria sp. to deplete TPH in the soil in treatment was also ascertained.

Naturally growing wild plant species were identified for accumulation of heavy metals at fly ash different disposal sites of Thermal Power Plant Gandhinagar. Cd, Fe, Zn, Cu, Ni, Pb and Cr metals were selected for studying accumulation by indigenous plants. Nine major weed species growing dominantly at fly ash dumpsite were identified i.e. Prosopis juliflora, Ipomea carnea, Calotropis procana, Nerium indicum, Abutilon indicum, Tephrosia purpunea, Cassia tora, Parthenium hysterphorus, Jatropha gossypifolia. Results showed significant accumulation of fly ash heavy metals by indigenous identified plants positive pattern of accumulation differed significantly in different weed species. Roots showed higher accumulation of heavy metals as compared with shoot in most of the plants but in some shoots also showed more accumulation compared to roots. Both translocation factor and bioaccumulation factor was calculated to determine metal translocation from site to roots and from root to shoot. Current results suggest that these plants species can effectively survive in harsh environment and can be used for eco-restoration purpose and also they can be used as potential phytoremediation species.

Fungal population dynamics was monitored in an oil-polluted soil undergoing remediation by enhanced natural attenuation (RENA) at Ibaa, Emohua L. G. A. Rivers State. Total petroleum hydrocarbons (TPH) and polycyclic aromatic hydrocarbons (PAHs) were determined from baseline [pre-RENA (POL B)] and sampling days 0 (POL 0), 9 (POL 9), 18 (POL 18), 36 (POL 36) and day 56 (POL 56)] using gas chromatographic-mass spectrometry.  The baseline TPH and PAHs were 9,146.65 ppm and 3,454.10 ppm in the polluted soil (pre-RENA) and 479.67 ppm and 279.72 ppm for unpolluted soil (pristine control) respectively. By day 56, percentages of contaminants degradation were 97% and 89% for TPH and PAHs respectively. Higher counts for both heterotrophic fungal (THF) counts and culturable hydrocarbon utilizing fungal (HUF) counts were obtained on day 36 with values of 5.6 x 105 cfu/g and 4.77 x 106 cfu/g respectively. Out of the 47 HUF isolated and characterized, 34 hydrocarbon utilizing fungi were isolated in the active phase between day 9 (POL 9) to day 36 (POL 36).  These recovered hydrocarbon degrading fungal isolates associated with the active phase of hydrocarbon degradation (Mucor sp., Malbranchia sp., Prototheca sp., Cladosporium spp., Trichosporon sp., Acremonium spp., Rhizomucor spp.). RENA treatment effectively reduced the pollutant levels in the impacted soil.
