Effective Growth

The potential of three micro-organisms (Pseudomonas, Streptococcus and Bacillus sp) were isolated from hydrocarbon contaminated soil and were evaluated for their biodegradation ability. The rate of biodegradation of the engine oil in the soil samples were exposed to used engine oil with different exposure rates of 5,10,15 and 20 years  were studied for a period of three (3) weeks under greenhouse experiment. The soil samples were obtained from four different mechanic workshops in M.M.C and they were plated on nutrients agar and oil agar medium to isolate the bacterial species from the spilled soil samples. All the micro-organisms used in this study showed their abilities to remediate soil exposed to used engine oil and the remediated soil samples were able to support the growth of Maize ( Zea mays) after 10 years  effective growth

The populace are concern about how their environment is impacted by spend or used engine oil. The spills from spend engine oil posed serious problems to the land and aquatic habitats. Efficient methods but low-cost technique for remediating spends engine oil contaminated soil and restorations of soil fertility are being explored. In response to used engine oil pollution to the soil, the present investigation examined the comparative biodegradation level of spend engine oil contaminated soil using fermented chicken droppings. The soil sample was collected from the uncontaminated site 10 cm below ground level. The sandy/loam soil was sieved with 2.5 mm mesh. A 4 kg of the soil was weighed into each bucket and contaminated with spend engine oil, the soil was contaminated with 150 ml of the spend engine oil at a ratio of 1:27. A 27 kg of chicken droppings was mixed with 27 liters of water in a ratio of 1 kg: 1L. The mixture was left for 7days to ferment and increase the microbial load. The contaminated soil was irrigated using an experimental design that included uncontaminated soil that was irrigated using normal water (positive control), contaminated soil that was irrigated using normal water (negative control) and contaminated soil irrigated using fermented chicken droppings (test). Five hundred mL of the chicken droppings mixture was used to irrigate the soil for 21 days at an interval of 3 days per irrigation. Thereafter, the irrigated soil was screened with gas chromatography linked with mass spectroscopy. There was an observed change in contaminant concentration without fermented chicken droppings. The percentage of differences in the concentrations was recorded in × 10–5% with the presence of Naphthalene and Acenaphthylene with the percent difference of 2.0 × 10–5% and 5.0 × 10– 5%. Result revealed an appreciable decrease in PAHs level compared to the positive and negative control. The findings suggest the positive effect and rapid uptake of the contaminant in the application of fermented chicken droppings. J. Bio-Sci. 29(1): 01-09, 2021 (June)

The assay was conducted in Pelotas, Rio Grande do Sul-Brasil, to compare the effect of used engine oil with to paraquat (Gramoxone) applied during the physiological maturition of soybean seeds (Glicyne max (L.) Merrill), Bragg variety. The oil doses were 5.3, 8.5 and 12 l/ha. The desiccation intensity was determined and 30 pods per plot were periodically collected to follow the humidity content of the seeds, to 18%. The humidity was later reduced to 10.5 +0.5 and 2.0 kg of seeds were stored, in cotton bags,during 6 months under the environmental conditions at the Centro de Entrenamiento de Semillas of the Federal University of Pelotas. The seeds were subjected to germination, vigor and phytosanitary tests at harvest time and after 3 and 6 months of storage. Under the conditions of this trial, the doses of 12 l/ha of oil and 2 l/ha of paraquat: a) act as desiccants for soybean plants, b) favors the production of seeds with better viability and vigor after 6 months of storage and c) guarantied better sanitary seed quality after 6 months of storage.
