| Summary: | In a separate laboratory study evaluating the effectiveness of 10 commercial products in stimulating enhanced biodegradation of Prudhoe Bay crude oil, two of the products provided significantly greater alkane degradation in closed flasks than indigenous Alaskan bacterial populations supplied only with excess nutrients. hese two products were then taken to an actual Prince William Sound beach to determine if similar enhancement were achievable in the field. andomized complete block experiment was designed in which four small plots consisting of a no-nutrients plus the two products were laid out in random order on a contaminated beach in Prince William Sound. hese four plots comprised a "block" of treatments, each block being replicated four times on the same beach. riplicate samples of beach sediment were collected at four time intervals and analyzed for oil residue weight and alkane hydrocarbon profile changes with time. esults indicated no significant differences among the four treatments in the 27-day time period of the experiment. |
