| Abstract: | Acrylic acid was detected in sea water in which oysters had been maintained and was shown to be derived from unicellular algae containing dimethyl-β-propiothetin (DMPT). Anticoliform activity was noted in samples containing acrylic acid. Intensification of the effect was achieved in laboratory studies and Phaeodactylum tricornutum (DMPT present) caused a rapid decline of Escherichia coli populations in sea water and in oysters which had been fed this alga. Pavlova lutheri (DMPT absent) was ineffective against E. coli . |
