초록

Seventeen strains were isolated from soil, cattle rumen, cereal sewage dregs, insect on agar plate containing insoluble glucan as a sole carbon source from immobilized Streptococcus mutans, which produced alpha-1,3 glucanase for lysis of dental plaque. Among these strains isolated from soil, SW-522 and SW-713 that had appeared to produce the high level of alpha-1,3 glucanase, degraded insoluble glucan from S. mutans 97.6% and 49.4%, respectively in 5 hours. The activity of crude alpha-1,3 glucanase from SW-522 was 1.3mg insoluble glucan/min.mg protein. This enzyme was entirely degraded insoluble glucan on glass tube which produced by S. mutans in TH medium with 5% sucrose.
