研究了高CO2环境下对粉红虾副溶血性弧菌生长的抑制作用。从对虾中分离出一株菌株，鉴定为副溶血性弧菌。用鉴定的菌株接种粉虾，在空气、N2和CO2条件下20℃保存。接种后16 h， CO2处理的菌落数显著低于空气和N2处理。在稳定的CO2状态下，平板计数比在空气和N2状态下低log 3.6 ~ log 3.7。采用Gompertz方程和logistic模型拟合并模拟了副溶血性弧菌在对虾体内和体表的生长，确定了其生长速率参数。二氧化碳降低了相当于最大板数的参数值。
Growth depression of Vibrio parahaemolyticus in pink shrimp under a high CO2 atmosphere was studied. A strain was isolated from prawn and identified as V. parahaemolyticus. The identified strain was used to inoculate pink shrimp and stored at 20°C under air, N2, and CO2. The plate count under CO2 16 h after inoculation was significantly lower than those under air and N2. The plate count under a steady state of CO2 was lower by log 3.6 to log 3.7 than those under air and N2. The growth of V. parahaemolyticus in/on the shrimp was fitted and simulated using the Gompertz equation and a new logistic model, to determine its growth rate parameters. CO2 reduced the value of the parameter equivalent to maximum plate count.
