Contamination Levels

The study assessed the removal of total petroleum hydrocarbon (TPH) and polyaromatic hydrocarbons (PAHs) from spent engine oil (SEO) contaminated soil through bioenhancement of bacteria isolated from SEO polluted soil. Sterilized soil was subjected to a three level of SEO contamination before the addition of sterilized biostimulants including powdered cow dung (CD), powdered cocoa pod husk (CPH) and compost (made from fresh CPH and CD). Bacterial inoculum being Staphylococcus aureus and Bacillus cereus co-culture (150 mL) was added to the mixture in polyethylene bags. It was a factorial experiment that was laid out in a completely randomized design (CRD). The TPH and PAHs were estimated in the first day, fifth week and the tenth week that the room incubation lasted. Results generated from the influence of biostimulants on TPH and PAHs degradation potential of the bacterial co-culture showed that degradation of the hydrocarbon contents was significantly enhanced (p < 0.05). At the tenth week, compost enhanced the most TPH reductions (315 and 380 mg kg–1) compared with other biostimulants on 5% and 15% SEO contamination levels, respectively. Compost equally enhanced the most PAHs reductions (48.8, 39.6 and 94.6 mg kg–1) compared with other biostimulants on 5%, 10% and 15% SEO contamination levels respectively. However, the quantity of SEO contents degraded was significantly higher in the bioaugmented and biostimulated soil samples compared with the control employed. The technology adopted in this study can be effectively employed for the bioremediation of petroleum hydrocarbon related pollution.

Before And After

The research aimed to investigate the bioremediation of spent engine oil on selected contaminated soils within Ilorin metropolis. To achieve this, soil samples were collected from three (3) mechanic workshops along Taiwo axis within the metropolis. The soil samples were then subjected to bioremediation using the land-farming approach. The physicochemical parameters of the soil samples before and after bioremediation were analyzed using standard methods. Bacteria were isolated using standard procedures and identified using biochemical tests and molecular methods. Results for the physicochemical parameters of the soil samples before bioremediation include particle size (all sandy in nature); pH (6.00 ± 0.14 - 6.20 ± 0.14); Organic carbon (14.65 ± 3.20 - 17.54 ± 1.87), Organic matter (33.50 ± 0.85 - 43.45 ± 9.12) and heavy metals (ND - 11.74 ± 0.07). Values after bioremediation for pH, organic carbon, organic matter and heavy metals were 8.25 ± 0.07 - 8.90 ± 0.14, 13.07 ± 0.05 - 13.25 ± 0.84, 37.25 ± 1.06 - 44.80 ± 1.13, ND - 9.40 ± 0.04 respectively. Values for bacterial count before and after bioremediation of the soil samples were 8.00  1.41 - 67.50 ± 2.12 x 105 CFU/mL and 6.50 ± 2.12 - 164.00 ± 11.31 x 105 CFU/mL respectively. Bacterial isolates were identified as Pseudomonas sp., Enterobacter sp., Acinetobacter sp., and Bacillus sp. while the hydrocarbon-utilizing bacteria were identified as Thalassospira mesophila strain JCM 18969; Pseudomonas fluorescens F113; Siccibacter turicensis LMG 23730; Pseudomonas Zeshuii strain KACC 15471; Pseudomonas stutzeri strain CGMCC 1.1803 and Marinobacter hydrocarbonoclasticus strain ATCC 49840. In conclusion, the bacteria isolates effectively bioremediated the spent engine oil contaminated soils with a reduction of hydrocarbon pollutants.

While strategizing towards achieving improved soil fertility for sustainable tropical crop production, timely application of fertilizers on regular basis alone is not the University of Technology, Ogbomoso, Oyo State, Nigeria best approach, particularly on polluted soils. However, seeking for reliable natural, biological and environment friendly means of ensuring effective riddance of toxic elements or heavy metals from tropical agricultural soils is equally a worthwhile technology. An open-field potted experiment was conducted during early raining season of 2016 (March-July), at the Teaching and Research Farms of Oyo State College of Agriculture and Technology, Igboora, to investigate the effect of spent engine oil polluted soil conditions on performance and heavy metal accumulation potentials of Ceratothecasesamoides. Spent engine oil was applied at different concentrations (0.0ml, 50.0ml, 100.0ml, 150.0ml, and 200.0ml to each pot containing 7kg soil. Four pots per treatments were used. The trial was arranged in Completely Randomised Design (CRD), replicated three (3) times. Data were collected on growth parameters (number of leaves, plant height, stem girth, leaf length and leaf breadth). The data were subjected to analysis of variance (ANOVA) and Duncan Multiple Range Test (DMRT) was used to the means. Pre and post-cropping soil analyses were carried out, for determination of nutrient concentrations. Also, after the termination of the experiment, plant samples were collected from each of the pots for oven-drying followed by determination of nutrient concentrations (including the heavy metals). Oil pollution significantly affected growth and heavy metal accumulation of the test-crop. Growth decreases with increasing rate of lubricant application, while the heavy metal concentrations in the test-crop increased with increasing concentrations of the applied spent engine oil. Thus, Ceratothecasesamoides is a wild plant which could be easily exploited for its heavy metals hyper-accumulative or phyto-extractive potentials, so as to reclaim heavy metals polluted soils from toxicity, for sustainable crop production.

The effect of different levels of spent engine oil application on germination, survival, growth, leaf anatomy, yield, nutrient content and heavy metals uptake of okra (Abelmoschus esculentus – ‘Clemson’ spineless variety and ‘OLA 3 Local’ variety) was assessed in the present study. Completely randomized design was used with five treatment levels of spent engine oil at 0 ml (control), 50 ml, 100 ml, 150 ml and 200 ml applied to 5 kg of soil. Data on germination, seedling survival, growth, chlorophyll nutrient and heavy metal content, as well as leaf epidermal features collected from the study were subjected to Statistical Package for Social Sciences (SPSS) analyses. Spent engine oil at 200 ml per pot significantly (P < 0.05) delayed seed germination for 4 days and reduced germination percentage by approximately 24% compared to the control. Plant height, number of leaves, leaf area, chlorophyll A, B and stomata area were reduced by 21.33-72.89%; number and dry weight of fruits were reduced by 67.4-13.58%. Number of stomata was increased on the adaxial surface by 57.73% and on the abaxial surface by 34.99%. Na, K, Cr, Cd and Fe contents increased by 0.0178-6.2698 mg/kg-1. The present study has shown that plant constituents and anatomy can be influenced by spent oil contamination. Contamination of soil with spent engine oil therefore should be avoided in order to ensure sustainable crop plant productivity and to reduce the risk of heavy metals toxicity for human beings.

Nauclea Diderrichii

Remediation of environmental pollution has been of great concern in recent years. This study was carried out to investigate the potentials of Nauclea diderrichii seedlings to remediate heavy metals from spent engine oil (SEO) contaminated soil. SEO from diesel and petrol engines in different quantities were applied to each plant using 2 kg soil. Plant height, collar diameter, number of leaves, root length were assessed. Amount of lead and cadmium present in the leaves, stem and root of the seedlings were assessed at the end of the experiment. Result showed that 100 % of the seedlings subjected to various treatments survived for the duration of 5 months. There was no significant difference (α>0.05) in the height of N. diderrichii seedlings. Significant (α=0.05) negative reductions were observed in the seedlings collar diameter, no. of leaves and root length. There was significant difference (α>0.05) in the amount of lead and cadmium extracted by N. diderrichii seedlings. This study has been able to show that N. diderrichii has the ability/potential to phyto-extract heavy metals from soil. Bangladesh J. Sci. Ind. Res.55(4), 261-272, 2020
