蛭弧菌指示和净化海水的研究

Abstract

[中文文摘]厦门近岸海水海洋噬菌蛭弧菌的数量与海水中弧菌类的数量成正相关．灭菌海水中只加蛭弧菌，其数量出现负增长．若同时加入蛭弧菌和宿主菌鳗弧菌８９２７菌株，则蛭弧菌数增加、增加速率随宿主菌浓度增加而增加，并导致宿主菌数减少，此时宿主菌随培养时间延长而减少，但减少速度缓慢，１５ｄ仅减少２６％．[英文文摘]There was a positive correlation between the quantity of marine Bdellovibrio and that of Vibrio in the sea water. The number of Bdellovibrio was decreased when it was lonely added into the steile water, whereas the number of Bdellovibrio was increased when it was added into the steile water with V.anguillarum 8927,which was a host for Bdellovibrio.The rate of growth of Bdellovibrio was proportionably increased with the concentration of V.anguillarum 8927. The growth of Bdellovibrio resulted in the diminution of V.anguillarum 8927。
