Analysis of enzymatic activities for differentiation of two species of nutritionally variant streptococci, Streptococcus defectivus and Streptococcus adjacens.

Abstract excerpt

Strains of nutritionally variant streptococci, Streptococcus defectivus (n = 10) and Streptococcus adjacens (n = 20), were studied for the production of glycosidic and proteolytic enzyme activities. S. defectivus strains produced neuraminidase and alpha-fucosidase, while S. adjacens strains produced only neuraminidase. The S. adjacens strains produced a very wide range of proteolytic activities with the ability...
