Effect of the dispersant corexit 9527 on the microbial degradation of prudhoe bay canada oil



Effect of the dispersant corexit 9527 on the microbial degradation of prudhoe bay canada oil



Canadian Journal of Microbiology 28(1): 117-122



A marine oil-degrading population grown at 8.degree. C showed a selective sensitivity regarding utilization of compounds in Prudhoe Bay oil in the presence of the dispersant Corexit 9527. The response was dependent on the N and phosphate levels of the medium and on the concentration of dispersant used. In the presence of a N phosphate solution and a Corexit 9527, crude oil substrate, degradation of the n-alkanes of the saturate fraction was temporarily retarded in proportion to the concentration of Corexit 9527 present. This retardation was overcome with extended incubation time. In the absence of N-phosphate supplementation, the effect of Corexit 9527 was pronounced, retarding n-alkane degradation even with extended incubation time. Corexit 9527 had less effect on the degradation of the aromatic fraction and may indeed be stimulatory in the case of select compounds. The development and testing of dispersants containing nitrogen and phosphate is recommended.
