Utilizing Corn Cob for the Bioremediation of Diesel-Contaminated Soil
Subject area: Agriculture and Veterinary Sciences · Area of research: Bioremediation
Abstract
This research explores the efficacy of corn cob material in remediating diesel-contaminated swampy soil. Biodegradation of diesel hydrocarbons is crucial for restoring soil health, as contamination can impair plant growth and render soil infertile for agricultural and domestic uses. In the study, corn cob was processed by drying it under sun and room temperature, then crushed and sieved into particle sizes ranging from 0.37 mm to 1.86 mm for room-dried (RT) and sun-dried (ST) samples. Different weights of corn cob (25g, 50g, 75g, and 100g) were added to 500g of diesel-polluted soil and assessed over a period of 10 weeks with sampling intervals of 2 weeks. The results showed that room-dried corn cob was more effective in reducing total hydrocarbon concentration (THC) compared to sun-dried corn cob, likely due to nutrient loss in the latter from exposure to sunlight. A reduction of over 80% in THC was achieved with the 100g application of room-dried corn cob. Further analysis using Lineweaver-Burk plots provided insights into the maximum velocity (Vmax) and Michaelis-Menten constant (Km) values, which helped in evaluating the bioremediation potential of the material. The findings indicate that corn cob is a promising and effective bioremediant for cleaning up swampy soil contaminated with petroleum hydrocarbons, and its use should be considered in bioremediation strategies for polluted soils.
