The potential of six microorganisms (Pseudomonas aeruginosa, Micrococcus sp, Flavobacterium sp, Rhizopus sp, Penicillium sp and Fusarium sp) isolated from hydrocarbon contaminated site were evaluated for their biodegradation ability. The soil samples were contaminated with 5% (w/v) of spent engine oil and the rate of biodegradation of the oil was studied for a period of 10weeks under greenhouse experiment. The total heterotrophic bacteria count (THBC), total hydrocarbon degrading bacteria count (THDBC), physicochemical and heavy metals properties of the soil samples and Total Petroleum Hydrocarbon (TPH) were determined after treatment with test organisms. THBC and THDBC ranged from 0.175 to 0.280CFUg -1 and 0.47 CFUg -1 respectively for the control plot, while THBC is ranging from 0.197 to 0.275 CFUg -1 and THDBC was 0.180 to 0. 473 CFUg -1 for the contaminated plot. There was a slight increase in the pH value of the contaminated soil sample and the treated soil samples as the experimental weeks increased. The results obtained showed a significant decrease (at p ≤ 0.05) in the nutrients content of the soil samples. There was an increase from 1.09 in the control to 15.5% in the content of organic matter after contamination and from 1.88% to 26.8% in the % of organic matter too. There was a significant reduction (at p ≤ 0.05) in the concentration of Fe, Zn, Pb, Cd, Cu, Cr and Ni after 10 weeks of incubation with the tested organisms. Plant growth in the treated contaminated soil samples ranged from 32.6cm to 38.6cm, while that of the control 1 (Uncontaminated soil) was 51.2cm and 19.7cm high was observed in the Control 2 (contaminated untreated soil) after 22 days of the experiment. The TPH degradation (% loss) ranged from 79.7 to 89. 2% after 10 weeks of treatment. P. aeruginosa had the highest level of degradation (89.2%), while Micrococcus sp and Rhizopus sp had the least degradation at 79.9%.All the microorganisms used in this study had the abilities to remediating soil contaminated with spent engine oil and the remediated soil samples were able to support the growth of Zea mays at 5% (w/v) level of contamination.

“…Farmers practice intercropping with a wide array of crops, consisting ordinarily of a major crop and other insignificant crops, however, it is pertinent that the selection of compatible crops be given priority as this depends on their growth habit, land, light, water and fertilizer utilization (Thayamini & Brintha, 2010). Intercropping plays a vital role in subsistence food production in both advanced and emerging countries (Adeoye et al, 2005). Legumes can relocate fixed N to intercropped cereals through their joint…”

Low forage quality and low corn yield experienced due to continuous monoculture resulting from persistent soil depletion in the developing world have generated the need for a sustainable practice to improve quality and yield of aforementioned. This review examines the salient issues that relates to the effect of intercropping some selected legume in different cropping patterns with corn in order to improve the yield and forage quality of corn, and that of quality feed/forage production. Two legumes species namely: Bambara groundnut and Peanut were the key crops focused with the main corn crop in this review work.

Bioremediation is an eco-friendly process that makes use of microorganisms to break down hazardous compounds like hydrocarbons into simpler and innocuous compounds. In this study, hydrocarbon degrading microorganisms were isolated from contaminated soil samples. Isolated microorganisms were identified and screened for their biodegradation abilities in aerobic conditions. The soil samples were contaminated with 5% (w/v) of spent engine oil and total heterotrophic bacteria count (THBC) and total hydrocarbon degrading bacteria count (THDBC) were determined by plate count method, while physicochemical and heavy metals properties of the soil samples were analysed by titrimetric and atomic absorption Spectrophotometry respectively. Gravimetric analysis was used to determine Total Petroleum Hydrocarbon (TPH) after treatment with test organisms. THBC and THDBC ranged from 175 -280 × 10 5 CFU/g and 47 -95 × 10 3 CFU/g respectively for the control plot, while THBC ranged from 197 -275 × 10 3 CFU/g and THDBC was 180 -473 × 10 5 CFU/g for the contaminated plot. Six microorganisms; Pseudomonas aeruginosa, Micrococcus sp, Flavobacterium sp, Rhizopus sp, Penicillium sp and Fusarium sp were isolated from hydrocarbon contaminated sites. The results obtained from the greenhouse experiment showed a significant decrease (at p ≤ 0.05) in the nutrients content of the soil samples. There was an increase from 1.09 in the negative control to 15.5% in the content of organic matter after contamination and from 1.88% to 26.8% in the % of organic matter too. There was a significant reduction (at p ≤ 0.05) in the concentration of Fe, Zn, Pb, Cd, Cu, Cr and Ni after 10 weeks of treatment with the tested organisms, but increase in pH values was observed in all the treatments. The TPH degradation (% loss) ranged from 79.7% -89.2% after 10 weeks of treatment. P. aeruginosa had the highest level of degradation (89.2%), while Micrococcus sp and Rhizopus sp had the least degradation of 79.9%. This study showed that all the bacteria isolated from the spent engine oil contaminated soil were able to degrade the spent engine at concentration of 2% (w/v). Soil samples also supported the growth of Zea mays after six weeks of treatment. Therefore, all the isolated bacteria can be used in biodegradation experiment.Citation: Ayandele, Abiodun A, 2018.
