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
