Abstract:
Enzymes
responsible for the digestion of food protein by juvenile green abalone
(Haliotis fulgens) were studied when fed algae or a sea grass (Phyllospadix
torreyi) naturally occurring in the habitat. The effect of food on the
composition and activity of the enzymes was also evaluated. Acid, serine
proteinases and aminopeptidases, as confirmed by pH profile of activity,
specific inhibition and synthetic substrate hydrolysis were found in the
digestive organs of juvenile green abalone. Algae and sea grass
differentially affected the digestive system in abalone.
