Abstract

A study was undertaken to find methods for enhancing rates of hydrocarbon biodegradation in gasoline-contaminated soil by ex-situ bioremediation. Garden soil was treated with gasoline-spilled soil from a gasoline station and different combinations of amendments were prepared using mixed bacterial consortium, poultry litter, coir pith and rhamnolipid biosurfactant produced by Pseudomonas aeruginosa. Bacterial growth, hydrocarbon degradation and growth parameters of Phaseolus aureus RoxB (including seed germination, chlorophyll content, shoot and root length) were measured for a period of 90 days. Approximately 78% of the hydrocarbons were effectively degraded within 60 days in soil samples amended with a
