A selective medium was developed on which both major subgroups of Strep. mutans (c/e/f and d/g) can be cultured and recognized on the basis of colonial morphology, Trypticase, yeast, cystine (TYC) agar was modified by adding separately autoclaved sucrose to a final concentration of 20 per cent and 0.1 unit/ml bacitracin (TYCSB). This medium yielded significantly higher counts of Strep. mutans than the widely used mitis-salivarius bacitracin (MSB) medium.
一种选择性培养基被开发出来，在其上变形链球菌的两个主要亚群（c/e/f和d/g）都能够基于菌落形态进行培养和识别。胰蛋白酶、酵母、胱氨酸（TYC）琼脂通过分别添加终浓度为20%的经高压灭菌的蔗糖和0.1单位/毫升杆菌肽（TYCSB）进行改良。这种培养基所培养出的变形链球菌数量显著高于广泛使用的轻唾杆菌肽（MSB）培养基。
