Polyethylene glycol (PEG) dehydrogenase in crude extracts of a PEG 20,000-utilizing mixed culture was purified 24 times by precipitation with ammonium sulfate, solubilization with laurylbetaine, and chromatography with diethylamino-ethyl-cellulose, hydroxylapatite, and Sephadex G-200. The purified enzyme was confirmed to be

Cercariae immobilisation and Schistosoma mansoni adult recovery tests in the mouse show that tensides can greatly reduce the infectivity of cercariae. In the case of two amphoteric products, Laurylbetain and Laurylamidopropylbetain, this action is obtained with very low (0.1-5 ppm)
