用微量量热计测定了大肠杆菌、金黄色葡萄球菌、白色葡萄球菌和枯草杆菌 ,在牛肉膏汤液体中不同温度下的产热曲线 按限制性条件下微生物生长模型进行了处理 ,求得了细菌的生长速率常数k、衰减速率常数 β和在实验条件下细菌增长的最大倍数M和细菌的最大数目K ,建立了细菌生长速率常数k和细菌生长温度T的定量关系 ,得到k=0时的温度T0 ,即细菌的最低生长温度
Escherichia coli, Staphylococcus aureus, Staphylococcus aureus and Bacillus subtilis were measured by microcalorimeter. The heat production curves at different temperatures in beef paste soup liquid were treated according to the microbial growth model under the restrictive conditions, and the bacteria The constants of growth rate k, decay rate constant β and the maximum multiplication of bacteria under experimental conditions M and the maximum number of bacteria K established the quantitative relationship between bacterial growth rate constant k and bacterial growth temperature T, Temperature T0, the lowest growth temperature of bacteria
