Degradation of crude oil enhanced by commercial microbial cultures Conference Paper uri icon


  • Remediation and cleanup of oil spills has been attempted using different technologies. Biological methods such as bioremediation have been favored over others due to their cost efficiency and their low environmental impact. Bioremediation of Alaska North Slope crude oil was effectively attempted in a laboratory study using 13 commercial products. The products containing the microorganisms were provided by different vendors. The treatments were tested over a 28-day period, and the samples -were extracted and analyzed using standard methods. After 28 days, four products showed an effective enhancement of the bioremediation process: the saturate fraction was degraded approximately 80%, and the aromatic fraction was degraded approximately 70%. Biological markers such as pristane, phytane, and Cm hopane were partially degraded.
