Abstract

This study was examined digestive enzyme activity in the crystalline style of the three species of bivalves. Bivalves used in this study were Tegillarca granosa (n=61), Mytilus galloprovincialis (n=30) and Saxidomus purpuratus (n=30) and collected from southern coast of Korea on May 2010. Digestive enzymes activities in the crystalline style were assayed in spectrophotometer. Amylase and cellulase occupied approximately 90% of digestive enzyme in crystalline style of T. granosa, M. galloprovincialis, and S. purpuratus. And protease activity in crystalline style of T. granosa, M. galloprovincialis and S. purpuratus showed the lowest values to 0.02, 0 and 0.08%, respectively. Digestive enzyme activity in crystalline style of three species was measured in the order of cellulase > amylase > chitinase > laminarinase.

연구는 3종의 이매패류를 대상으로 당면체의 소화효소 활성에 대해 조사하였다. 본 연구에 사용된 이매패류는 꼬막(n=61), 지중해담치 (n=30) 및 개조개 (n=30) 이며, 이들은 한국 남해안에서 2010년 5월에 채집하였다. 당면체의 소화 효소 활성 분석은 분광광도계를 이용하였다. 꼬막, 지중해담치, 개조개의 당면체를 구성하는 소화효소는 amylase와 cellulase가 약 90%로 대부분을 차지하였다. 그리고 꼬막, 지중해담치, 개조개의 당면체를 구성하는 소화효소 중 protease 의 활성도가 가장 낮았으며, 각각 0.02, 0, 0.08%로 나타났다. 당면체를 구성하는 소화효소 활성도는 3종 모두 cellulase > amylase > chitinase > laminarinase의 순으로 나타났다.
