A field study on the acute effects of the dispersant corexit 9527 on glucose uptake by marine microorganisms



A field study on the acute effects of the dispersant corexit 9527 on glucose uptake by marine microorganisms



Marine Environmental Research 5(2): 83-92



The effects of the dispersant Corexit 9527 and Corexit with crude oil on the rate of glucose uptake and mineralization were studied in Arctic and subarctic marine waters and sediments. The 149 water and 95 sediment samples displayed decreased glucose uptake rates in the presence of 15 or 50 ppm Corexit. Depressed uptake rates were observed at concentrations as low as 1 ppm. The mean concentration at which Corexit depressed glucose uptake by 50% was 12 ppm. The effect of Corexit was more pronounced on pelagic than on benthic microbial populations.
