摘要: Total and insoluble dextransucrase activities of 10 strains oral streptococci were measured by a modified filter disk assay. Strains that nonadherent to hard surfaces had only low levels activity.A physical rather than metabolic mechanism is suggested explain the decreased increased soluble observed when dextran T-10 added media.
