一般描述

通过改良Green和Gray的配方配制的WL（Wallerstein Laboratory）鉴别琼脂，可用于检测酿造过程中的材料以及含有酵母和细菌混合菌群的工业发酵物。WL鉴别琼脂有助于选择性分离和计数啤酒厂和工业发酵中遇到的细菌。

应用

WL鉴别琼脂已用于马克斯克鲁维酵母培养基计数。

制备说明

将80.26 g悬浮于1L蒸馏水中。 加热至沸腾以完全溶解培养基。在121°C下高压蒸汽灭菌15分钟。如果需要得到6.5的pH值，添加1%碳酸氢钠溶液。

附注

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。
