| Popis: | The majority of Ruminococcus flavefaciens strains isolated in our laboratories failed to grow or grew poorly both in rumen' fluid medium and in a chemically defined medium containing all the nutrients reported to be required for good growth of this species. ttemptsw ere made to developa defined medium wnicnw ould support good growth of the R. flavetaciens s trains studiedo. ver 70 differentm edium formulationsf ree of rumen fluid were tried.
