Abstract

Most haemolytic group B streptococci produced a yellow to orange pigment in Colombia agar and in some Todd Hewitt broths. The composition of the broth medium was important. Trypsin inhibited pigment production, but had no effect on pigment already produced. Optical density measurement revealed three main peaks at 420, 260 and 215 nm respectively with pigment producing strains. Nonpigmented strains gave only the two peaks at 260 and 215 nm.

摘要

大多数B族溶血性链球菌在哥伦比亚琼脂和某些托德-休伊特肉汤中产生黄色至橙色色素。肉汤培养基的成分很重要。胰蛋白酶抑制色素产生，但对已产生的色素没有影响。光密度测量显示，产色素菌株分别在420、260和215nm处有三个主峰。无色素菌株仅在260和215nm处有两个峰。
