General description
MRS 肉汤用于从所有类型的材料中富集、培养和分离所有种类的乳酸杆菌(根据 DeMan、Rogosa 和 Sharpe 的报道)。该培养基可用于从 MRS 琼脂中分离出的菌落的确认测试。MRS 培养基含有聚山梨醇酯(Tween 80)、醋酸盐、镁和锰,这些都是乳酸杆菌的已知的特殊生长因子,并且是丰富的营养基础。由于这些培养基显示出非常低的选择性,片球菌和明串珠菌以及其他继发细菌可能会在其中生长。大多数伴随的微生物群落可以被醋酸铊、山梨酸、醋酸、亚硝酸钠、放线菌素和多粘菌素抑制。这些物质可以以不同的浓度和组合使用,但不可避免地必须在有机体的选择性和回收率之间达成妥协。
Application
MRS 肉汤用于从所有类型的材料中富集、培养、分离所有种类的乳酸杆菌。
