AbstractAbstract
[en] The feasibility of developing natural dispersants (biodispersants) for use in response to a marine oil spill was discussed. In this study biochemical tests were conducted with Bacillus and Coccus Gram Positive bacteria in order to select the one marine microorganism which is capable of producing biodispersants to degrade crude oil. Different carbon sources and salt concentrations were used in the experiments. A second experiment was conducted in which the production of biodispersants by the pure microbial strain were studied by measuring interfacial tension, determined by using the Longman method. The surfactant efficacy and the dispersant stability of Arabian Light crude oil was also studied. The biological oxygen demand at five days, biological oxygen demand at the end of the biodegradation, the biodegradation constant and the biochemical stabilization constant were determined during the degradation process. 23 refs., 9 tabs.,4 figs
