[目的]研究在磷酸缓冲液中添加不同浓度海藻糖的条件下阪崎肠杆菌对高温、低温的耐受性,为食品加工过程中控制阪崎肠杆菌污染提供参考。[方法]通过试验观察阪崎肠杆菌在不同温度条件下存活状况来反映其对温度的耐受性。[结果]阪崎肠杆菌在一定的高温条件下,其存活率与海藻糖的浓度成正比。[结论]海藻糖对阪崎肠杆菌有保护作用,随着海藻糖浓度的升高,其保护作用越明显。

Objective The research aimed to determine tolerance of Enterobacter sakazakii to high and low temperature under the condition of adding different concentrations of trehalose in phosphate buffer solution ,so as to provide reference for control of E.sakazakii contamination in the process of food processing.[Method] Survival situation of E.sakazakii was used to reflect the tolerance to conditions of heat and cold.[Result] E.sakazakii in a certain temperature ,the survival rate was proportional to the concentration of trehalose. [Conclusion] Trehalose had a protective effect against inactivity of E.sakazakii and with the increasing concentrations of trehalose ,the protective effect was more obvious.
