研究了不同温度（10.5-24.5°C）、pH值（5.5-7.5）、氯化钠（0.25-6.25%）和亚硝酸钠（0- 200 ppm）对肠膜明串珠菌（Leuconostoc mesenteroides）在好氧和厌氧条件下预测生长速率和滞后时间的综合影响。开发的响应面（RS）模型提供了可靠的估计的三个动力学参数的研究，在有氧和厌氧条件下，分别与0.86和1.18之间的偏差因子和1.13和1.31之间的准确度因子。对于两种条件，SEP值范围在15.62%和27.63%之间。开发的模型是一个有价值的工具，使其应用程序的货架寿命估计的食品。
The combined effects of different temperatures (10.5–24.5°C), pH level (5.5–7.5), sodium chloride levels (0.25–6.25%) and sodium nitrite levels (0–200ppm) on the predicted growth rate and lag-time of Leuconostoc mesenteroides under aerobic and anaerobic conditions was studied. The response surface (RS) model developed provided reliable estimates of the three kinetic parameters studied, with a bias factor between 0.86 and 1.18 and an accuracy factor between 1.13 and 1.31, in aerobic and anaerobic conditions, respectively. For both conditions, SEP values ranged between 15.62% and 27.63%. The developed models are a valuable tool, enabling its application for shelf-life estimation of a food product.
