Enhanced Hydrocarbon Biodegradation Using Bioaugmentation With Biowishtm-Aqua Fog, Michael Robert Lehrer Jun 2012

Enhanced Hydrocarbon Biodegradation Using Bioaugmentation With Biowishtm-Aqua Fog, Michael Robert Lehrer

Master's Theses and Project Reports

This study was done to determine the effectiveness of a commercially available bioaugmentation product, BiOWiSHTM-Aqua FOG, for remediating petroleum-contaminated sandy soil. Biodegradation enhancement by BiOWiSHTM-Aqua FOG was evaluated in laboratory microcosms by directly measuring total petroleum hydrocarbon (TPH) and indirectly using respirometry. Attempts were made to enrich hydrocarbon-degrading bacteria in BiOWiSHTM-Aqua FOG, and the resulting enrichment cultures were screened using respirometry as well. Potential hydrocarbon-degrading bacteria in BiOWiSHTM-Aqua FOG were isolated. Experiments were performed at bench-scale using microcosm bottles containing sand contaminated with either motor oil or No. 2 diesel fuel. The ...
