| Research Abstract |
The Shiitake extracts inhibited the biofilm formation of Streptococcus mutans in dose dependent manner. By contrast, the extracts did not affect the growth of the planktonic bacterial cells. It was suggested that the effective components are produced in time dependent manner. In addition, it was elucidated that the enzymatic activity of S. mutans glycosyltransferases was inhibited by the Shiitake extracts. These results revealed the possibility that the effective materials from Shiitake and related species might be clinically available as drugs to reduce dental caries.
