DIGESTIVE ENZYMES IN AFRICAN GIANT LAND SNAIL (ARCHACHATINA MARGINATA) DURING AESTIVATION
The activities of digestive enzymes in the gut
regions of African giant land snail, Archachatina
marginata were investigated during aestivation
induced in the laboratory by the withdrawal of
water and food for three weeks. All studied
enzymes, amylase, α-glucosidase, cellulase, lipase,
and protease, were detected on the gut regions
(oesophagus, crop, stomach and intestine).
Aestivated snails had significantly lower enzyme
activities in all the gut regions than the active
snails. Furthermore the stomach recorded the
highest enzyme activities of all the gut region
