Application

用于检测和计数大肠菌,特别是水、牛奶和其他乳制品中大肠产气杆菌群的选择性培养基。

Preparation Note

将38.5 g悬浮于1L蒸馏水中,静置5分钟。加热至沸腾,并分装到平板或试管中。可以选择在 121°C 下高压蒸汽灭菌 15 分钟,但是如果培养基将在制备当日使用,则应进行灭菌。但是灭菌后,培养基可能会变得混浊。不灭菌可提高受压微生物的回收率。

Other Notes

美国公共卫生协会(APHA)推荐;对大肠菌群的研究
我们现提供两种类型的培养基:GranuCult®优质颗粒状培养基和NutriSelect®高性价比粉末状培养基,满足用户不同层次的需求。
商标后的品级称号basic(基础)、plus(加强)或prime(特级)代表产品的不同质控水平,从基础的质控到标准质控加强版到全面合规的特级质控水平。
