一般說明

脱氧核糖核酸酶试验琼脂推荐用于细菌和真菌脱氧核糖核酸酶活性的检测,尤其是用于病原性 Staphylococci 的鉴定。
将细菌划线接种到琼脂培养基的表面上并进行孵育。然后在培养基表面注满 1N 盐酸。在 1N HCl 存在的情况下聚合的 DNA 产生沉淀并使培养基模糊。如果微生物产生的脱氧核糖核酸酶的量足以水解 DNA,那么在菌落周围就可以看到透明的区域。

應用

for the detection of deoxyribonuclease activity of bacteria and fungi, and especially for identification of pathogenic Staphylococci

商品

显色培养基能够选择性检测金黄色葡萄球菌,该葡萄球菌产生的蓝绿色菌落与其他物种明显不同。

Chromogenic media enable the selective detection of S. aureus, which produce bluish-green colonies that are clearly differentiated from other species.
