    • Twenty animals were carefully dissected to obtain 52 g of hepatopancreas, which were homogenized in ca. 2.5-3 vol/w of acetate buffer 50 mM pH 5; clear protein solution (170 mL 1.19 mg/mL) was obtained after centrifugation. After dialysis and ultrafiltration the crude extract contained a final concentration of 6 mg/mL of total protein. Activities were measured using nitrophenyl glycosides substrates as described in Ref. 6 or lactose. One unit corresponds to the amount of enzyme hydrolyzing one nanomol of substrate in 1 min/mg of total proteins
