NEUTRALIZATION OF OIL SPILLS USING ECOLOGICAL SORBENT GLAUCONITE MODIFIED BY BIOSURFACTANTS OF PSEUDOMONAS SPP. PS-17
Journal Title: Baltic Coastal Zone - Year 2015, Vol 19, Issue
Abstract
The purpose of the present study was to investigate possible methods to enhance the rate of biodegradation of oil sludge from soil contamination by the petroleum products using glauconite modified by biosurfactants Pseudomonas spp. PS-17, thus reducing the time usually required for bioremediation. Enhancement of biodegradation was achieved through bioaugmentation and biostimulation. Contaminated soil samples were treated with ecological sorbent glauconite modified by biosurfactants Pseudomonas spp. PS-17. Maximum degradation was achieved after the 7 weeks of treatment. Measures against oil spill (gasoline, diesel fuel, motor oil) on parking areas, stations and highways could be carry out through the formation on the area perimeter the engineering chemical barriers with glauconite modified by biosurfactant Pseudomonas spp. PS-17 (10 g biosorbent per 1000 g glauconite). Application rate of glauconite modified with biosorbent is depending on the total oil content and range within 2.2-220 kg per m2, respectively and depend of a minor and extreme pollution.
