초록

작잠은 가잠과는 종속이 다른 섬유 곤충으로 우수한 섬유용 재료를 만든다. 최근 비섬유용 소재로 작잠 견단백질을 활용하기 위한 기초 연구의 일환으로 작잠 견단백질을 용해 조건에 대하여 연구 결과 작잠견사의 연감율은 16.8%로 나타났으며, 작잠견사는 염화칼슘 에탄올 혼합 용매에는 용해되지 않으나 질산칼슘수화물의 용융액에는 용해되었다. 질산칼슘과 에탄올의 조성비를 조정하여 낮은 농도의 질산칼슘 농도에서도 작잠견사가 용해되었다. 작잠 실크단백질의 주요 아미노산 조성은 알라닌, 글리신, 세리신으로 작잠 정련사와 유사한 조성을 보였다. 따라서, 금후 작잠 견단백질의 적절한 용해시스템 확보 및 소재개발을 위한 기초 자료로 활용될 수 있을 것으로 사료된다.

Antheraea pernyi silkworm is one of typical wild silkworms, which spins a tawny color cocoon. The cocoon has been used as a resource for textile material due to strong chemical stability and good mechanical properties. In this study, to increase the solubility efficiency of A. pernyi silk fibroin, the composition of dissolution solvent were examined. Calcium chloride tertiary system, normally used for dissolution of Bombyx mori silk fibroin, does not act on A. pernyi silk fibroin. Calcium nitrate system dissolves A. pernyi silk fibroin, and calcium nitrate ethanol system do more easily than calcium nitrate system. Amino acid composition of A. pernyi silk fibroin obtained after dissolution is mainly composed of alanine, glycine, and serine. A. pernyi silk fibroin would be used for non-textile applications near future.
