The death kinetics of Aspergillus niger spores under high-pressure carbonation were investigated with respect to the concentration of dissolved CO2 (dCO2) and treatment temperature. All of the inactivation followed first-order death kinetics. The D value (decimal reduction time, or the time required for a 1-log-cycle reduction in the microbial population) in the saline carbonated at 10 MPa was 0.16 min at 52 degrees C. The log D values were linearly related to the treatment temperature and the concentration of dCO2, but a significant interaction was observed between them.
研究了黑曲霉孢子在高压碳酸化条件下的死亡动力学与溶解二氧化碳（dCO2）浓度和处理温度的关系。所有的失活均遵循一级死亡动力学。在10 MPa下碳酸化的盐溶液中，52℃时的D值（十进制减少时间，即微生物群体减少1个对数周期所需的时间）为0.16分钟。对数D值与处理温度和dCO2浓度呈线性相关，但二者之间存在显著的相互作用。
