Available in PDF, EPUB and Kindle. Book excerpt: In the process of Savannah River Site (SRS) operations limited amounts of waste are generated containing petroleum, and radiological contaminated soils. Currently, this combination of radiological and petroleum contaminated waste does not have an immediate disposal route and is being stored in low activity vaults. SRS developed and implemented a successful plan for clean up of the petroleum portion of the soils in situ using simple, inexpensive, bioreactor technology. Treatment in a bioreactor removes the petroleum contamination from the soil without spreading radiological contamination to the environment. This bioreactor uses the bioventing process and bioaugmentation or the addition of the select hydrocarbon degrading bacteria. Oxygen is usually the initial rate-limiting factor in the biodegradation of petroleum hydrocarbons. Using the bioventing process allowed control of the supply of nutrients and moisture based on petroleum contamination concentrations and soil type. The results of this work have proven to be a safe and cost-effective means of cleaning up low level radiological and petroleum-contaminated soil. Many of the other elements of the bioreactor design were developed or enhanced during the demonstration of a ''biopile'' to treat the soils beneath a Polish oil refinery's waste disposal lagoons. Aerobic microorganisms were isolated from the aged refinery's acidic sludge contaminated with polycyclic aromatic hydrocarbons (PAHs). Twelve hydrocarbon-degrading bacteria were isolated from the sludge. The predominant PAH degraders were tentatively identified as Achromobacter, Pseudomonas Burkholderia, and Sphingomonas spp. Several Ralstonia spp were also isolated that produce biosurfactants. Biosurfactants can enhance bioremediation by increasing the bioavailability of hydrophobic contaminants including hydrocarbons. The results indicated that the diversity of acid-tolerant PAH-degrading microorganisms in acidic oil wastes may be much greater than previously demonstrated and they have numerous applications to environmental restoration. Twelve of the isolates were subsequently added to the bioreactor to enhance bioremediation. In this study we showed that a bioreactor could be bioaugmented with select bacteria to enhance bioremediation of petroleum-contaminated soils under radiological conditions.

Download or read book Enhanced Bioremediation of a Soil Contaminated with Both Petroleum Hydrocarbons and Heavy Metals with In soil Biosurfactant Production written by Faramarz Jalali and published by . This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils that are co-contaminated with petroleum hydrocarbons and metals account for 55% of all hazardous waste sites and are hard to decontaminate because of the different nature of the remedial treatment required. Biosurfactant-producing microorganisms are present in many environments and can be stimulated to produce them under favorable conditions. This dissertation investigates the effect of biosurfactant production by indigenous microorganisms of a co-contaminated soil. A soil that was heavily contaminated with petroleum hydrocarbons and metals was acquired from the Toronto Harbour area. Phase one of the study evaluated the extent of the biodegradation of organic pollutants as well as the feasibility of biosurfactant production by the produced microorganisms. Results show that by the end of the experiment (50 days) batches amended with nutrients produced biosurfactants up to 3 times their critical micelle concentration (CMC). The produced surfactants caused the concentration of TPH and metals in the filtrate to increase from 2 to 8% and from 2 to 4%, respectively. In the phase two of the experiments the production of biosurfactants was enhanced by 40% by limiting the inorganic source of nitrogen in the batches, following a short growth phase. The produced biosurfactants were able to wash 10% of TPH and 6% of the metal content of the soil. The results indicate that biosurfactants can be produced by the indigenous soil microorganisms using organic contaminants as the sole carbon source. Furthermore, the produced biosurfactants showed potential to enhance biodegradation of petroleum hydrocarbons as well as to improve flushing of the remaining soil pollutant from soil.
