The degradation of parathion in cultures of the marine dinoflagellate Porocentrum micans E (original) (raw)

Water Research, 1987

Abstract

Abstract The rate of degradation of parathion in laboratory cultures of a unicellular phytoplankton dinoflagellate, Prorocentrum micans E., was studied in conditions resembling the marine environment. When the parathion, at 1–5 ppm, was added in sterile culture medium there was no significant degradation after 2 months, whereas in the presence of populations of P. micans more than 95% was degraded in 10 days. The initial step of the biodegradation was a reduction to aminoparathion. This process corresponds to a detoxification of the medium.
