Abstract

The cell of Kluyveromyces fragilis yeast, which is worthy of an algal substitute, was disrupted by a chemical treatment to increase the digestion of filter-feeders that yeasts are fed to. The optimum conditions of the chemical treatment were obtained by incubating yeasts at 3$0^{\circ}C$ for one hour after treated by 1 M of Na$_{2}$-EDTA that was dissolved in 0.2 M of Tris-buffer and by 0.3 m of 2-mercaptoethanol. The percentage of protop[last production was about 30%. The percentage could be doubled by the pretreatment of three times of 30 seconds sonication.

효모를 먹이로 하는 filter-feeder들의 소화력을 높이고자, algae의 대용물로서 가치가 있는 Kluyveromuces fragilis효모를 화학적 처리방법에 의해 세포벽을 바괴시켰다. 화학적 처리방법의 최적조건은 0.2 M Tris-buffer에 용해시켜 만든 1M 의 $Na_2EDTA$와 0.3 M의 2-mercaptoethanol을 처리한 후 $30{\circ}C$배양기에서 1시간 배양하는 조건에서 얻어졌다. 이때, 약 30%의 protoplast yeast를 실시함으로써, 그 생성률을 약 2배이상 올릴 수 있었다.
