The growth rates of 30 different strains ofVibrio parahaemolyticus andVibrio alginolyticus at 37°C was determined. Each species consists of two major groups, one having a short generation time (12-14 min) and one with a longer generation time (20-25 min). The diversity in generation times of different strains belonging to the same species is discussed. The effect of temperature, salt, and nutrient concentrations on the growth rate of oneV. alginolyticus strain (NCMB 1803) was studied. The most striking is the effect of the temperature; at 39°C the generation time is 10-11 min, while at 21°C it is 60 min. The heat of activation for growth calculating from such data is 22,580 kcal/mole/hr(-1). The ecological significance of these results is discussed.
在 37°C 下测定了 30 株不同的副溶血性弧菌和溶藻弧菌的生长速度。每个物种都由两个主要群体组成，一个群体的代时较短（12-14 分钟），另一个群体的代时较长（20-25 分钟）。讨论了属于同一物种的不同菌株的代时多样性。研究了一种溶藻弧菌菌株（NCMB 1803）的温度、盐度和营养浓度对其生长速度的影响。最引人注目的是温度的影响；在 39°C 时，代时为 10-11 分钟，而在 21°C 时为 60 分钟。根据这些数据计算出的生长热激活能为 22580 千卡/摩尔/小时（-1）。讨论了这些结果的生态意义。
