Abstract

A halophilic V. vulnificus is an estuarine microorganism that has been associated with fatal wound Infection and life-threatening septicemia. Hemolysin is defined as toxic substance produced by various species of bacteria Including V. vulnificus. Hemolysin from marine V. vulnificus was purified and the effect of pH, temperature. metal ion on the activity of hemolysin, and thermostability of hemolysin were tested in this study. Hemolysin iysed the sheep red blood cell and the optimum pH was 8.0, the optimum temperature was 4$0^{\circ}C$, and $K^+$ increased but $Mn^{2+}$ decreased the hemolyic activity of hemolysin, but hemolysin was unstable to heat.

호염기성 V. vulnificus는 연안에 존재하는 미생물로서 치명적인 상처 감염과 생명을 위협하는 패혈증과 관련이 있다. Hemolysin은 V. vulnificus를 포함하는 여러 가지 세균종에 의해 생성되는 독성 물질이다. 본 연구에서는 해양 V. vulnificus에서 hemolysin을 정제한 후 hemolysin의 활성에 미치는 pH, 온도 및 금속 이온의 영향을 조사하였다. Hemolysin은 sheep red blood cell을 용혈시켰으며 hemolysin의 최적 pH는 8.0, 최적 온도는 4$0^{\circ}C$이었으며 $K^+$ 이온은 homolysin의 활성을 증가시켰으나 $Mn^{2+}$는 감소시켰다. 그러나 hemolysin은 열에 불안정하였다.
