Abstract
A recently developed blue dextran-agar assay was utilized to detect dextranase production by a large number of strains of Streptococcus mutans. An extract obtained from S. mutans strain B2 hydrolyzed high-molecular-weight radioactive dextran to oligosaccharides. There are several possible roles for this enzyme activity in the metabolism of S. mutans dextrans.
摘要
一种最近开发的蓝色葡聚糖-琼脂测定法被用于检测大量变形链球菌菌株产生的葡聚糖酶。从变形链球菌菌株B2获得的提取物将高分子量放射性葡聚糖水解为寡糖。这种酶活性在变形链球菌葡聚糖的代谢中可能有几种作用。
