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,...

Summary: | 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 regions.
Se investigaron las actividades de las enzimas
del tracto digestivo del caracol gigante africano
Archachatina marginata durante la estivación,
inducida en laboratorio mediante retirada del agua
y alimento durante tres semanas. Todas las enzimas
estudiadas, amilasa, α-glucosidasa, celulasa,
lipasa y proteasa fueron encontradas en las
regiones del tracto digestivo (estómago, intestino,
esofago y bulbo oral). Los caracoles en estivación
tienen, en todas las regiones del tracto digestivo,
actividades enzimáticas significativamente meno-
res que los caracoles activos. En el estómago, se
registró la mayor tasa de actividad enzimática de
todo el tracto digestivo. |
