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 .
