摘要: 对从奶制品中分离的65株阪崎肠杆菌的培养特征、生化鉴定、温度耐受性等进行分析研究,比较来源不同的菌株在生物学特性方面是否存在差异,了解从奶制品中分离的阪崎肠杆菌的热耐受情况、60℃存活时间以及4℃低温的耐受情况。结果表明,阪崎肠杆菌热耐受性与菌落形态特征、表型存在一定的相关性,65株菌都表现较为耐热和能够耐受4℃低温3个月以上。

Abstract: This study aimed to compare the biologic characteristics of 65 strains of Enterobacter sakazakii isolated from milk products,and make clear the heat tolerance,the survival duration under 60 ℃ and 4 ℃ environment of these strains.Results showed that the heat tolerance of E.sakazakii is correlative with its colony morphology and phenotypes.The 65 strains of E.sakazakii all have good heat tolerance,Which can tolerate 4 ℃ over 3 months.

Key words: milk product, Enterobacter sakazakii, temperature tolerance
