Resumo:
Marine polychaetes, collected from the Vellar Estuary exhibited arylsulfatase activity. Lumbriconeries sp. Polydora sp. Monojis sp. and Heteromastus sp. were selected for this study. Of these, Heteromastus sp. showed maximum enzymatic activity and it has been chosen for the enzyme kinetic studies such as pH, optimal temperature, period of incubation and the effect of DDT. Enzyme activity showed single peak at pH 6.2 possibly indicating the presence of one type of arylsulfatase. Maximum activity was attained after 12h of incubation at 29°C. DDT has an inhibiting effect on the arylsulfatase activity even at the concentration of 10 p.p.m. and the activity was completely lost at 100 p.p.m.
