Extracellular Enzyme Activity Profile in Chemically Enhanced Water Accommodated Fraction of Surrogate Oil from BP Oil Spill

Enzyme activity, dissolved oxygen, particulate organic carbon (POC), dissolved organic carbon (DOC), total organic carbon (TOC) and particle size were measured on the last day of two mesocosm experiments performed with open ocean and coastal water. Enzyme activity, polysaccharide, proteins, uronic acids, POC, TOC and DOC were measured in the top, middle and bottom layer of the tanks, dissolved oxygen was measured only on the top and bottom layer while particle size was measured only from the middle layer.
