Effect of temperature and pH on the growth ofAeromonas salmonicida
摘要
Abstract
In this paper, the effects of different temperatures and pH on the growth ofAeromonas salmonicida were studied. The results showed that plate count method could better reflect the true dynamic growth condition ofA. salmonicida. At the four temperature gradients (28, 15, 10 and 5℃), as the temperature decreased, thegrowth rate of A. salmonicida decreased obviously. Within the range of pH 6.0~8.0,A. salmonicida could grow, but its growth was significantly inhibited under acid conditions. The results also showed thatA. salmonicida had gained the high-est growth rate and the largest amount under the condition of 28℃ and pH 7.5. This study has a certain theoretical guiding significance to the actual production. In order to inhibit the growth ofA. salmonicida and reduce the infec-tion of the farmed fish,it is strongly suggested to reduce the temperature and control the pH value in aquaculture reasonably.关键词
