摘要: 研究添加大蒜素对假单胞菌液体和固体生长动力学模型的影响。结果显示:在液态纯培养条件下,随着大蒜素添加量的增加,假单胞菌生长动力学模型中的延滞期数值从1.9136降到-0.4665,最大比生长速率数值变为负值,从0.9107降到-0.0159;在冷鲜猪肉基质上,添加大蒜素后其生长动力模型中的延滞期数值从1.9796增到5.6249,最大比生长速率数值从1.0291降到0.8615。添加大蒜素对两个模型中最大比生长速率数值的影响趋势是一致的。本实验初步说明添加大蒜素对液体模型中最大比生长速率数值的影响,在一定程度上可以推断其对固体基质上假单胞菌的生长的影响。

Abstract: The effect of allicin on growth kinetics of Pseudomonas in liquid and solid matrices was studied. The results showed that under liquid culture conditions, the lag phase of Pseudomonas growth reduced from 1.9136 to -0.4665, and maximum specific growth rate from 0.9107 to -0.0159 with increasing allicin concentration. In chilled fresh pork, the lag phase of Pseudomonas growth increased from 1.9796 to 5.6249 while the maximum specific growth rate decreased from 1.0291 to 0.8615 under the stimulation of allicin. Allicin revealed consistent effect on the maximum specific growth rate during Pseudomonas growth in both matrices. Therefore, the effect of allicin on the growth of Pseudomonas under solid culture conditions can be inferred from the change of maximum specific growth rate under liquid culture conditions.

Key words: allicin, Pseudomonas, growth kinetic model, chilled fresh pork
