Abstract
Seventy-two isolates classified as "Streptococcus milleri" were examined for the presence of various hydrolytic enzymes. While no protein or lipid-degrading activities were demonstrated, some isolates showed DNase and mucopolysaccharide-degrading activities. Beta-hemolytic isolates were more likely to produce these enzymes than were nonhemolytic strains. Isolates of one "S. milleri" biotype (mannitol fermentation positive) were uniformly devoid of all enzyme activities tested.
摘要
对72株归类为“米勒链球菌”的分离株进行了各种水解酶的检测。虽然未显示出蛋白质或脂质降解活性，但一些分离株表现出DNase和黏多糖降解活性。β溶血性分离株比非溶血性菌株更有可能产生这些酶。一种“米勒链球菌”生物型（甘露醇发酵阳性）的分离株均未表现出所检测的所有酶活性。
