General description

玉米粉琼脂是一种通用型培养基，适用于培养真菌、研究菌丝体或假菌丝体形成以及研究厚垣孢子生产用念珠菌。来自玉米的玉米粉浸液（corn meal infusion）富含碳和氨基酸源，还有许多有助于真菌生长的其它微量元素。该培养基可添加聚山梨酯80进行改良，以刺激 白色念珠菌、星状念珠菌和 热带念珠菌中厚垣孢子的形成。聚山梨酯80是油酸酯的混合物，可刺激念珠菌 产生厚垣孢子。一些念珠菌在反复继代培养后失去形成厚垣孢子的能力。葡萄糖的加入促进了一些真菌的迅猛生长。培养基中的葡萄糖（2克/升）适用于常见植物病原真菌的培养。它也促进一些毛癣菌（如红色毛癣菌）的生色作用。含葡萄糖的玉米粉琼脂不可用于厚垣孢子的生产。

Application

玉米粉琼脂推荐用于白色念珠菌的厚垣孢子生产和真菌母种的继代培养。

Preparation Note

取17g溶于1L蒸馏水中。煮沸至完全溶解。如有需要添加1%聚山梨醇80。121°C高压蒸汽灭菌15分钟。

Other Notes

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。
