Two strains of Desulphovibrio desulphuricans were found to have much reduced hydrogenase activity for sulphate reduction and methylene blue reduction after repeated subculture in medium containing mimosa tannin. The loss of activity was not reversed on transfer back to a medium containing no tannin. Changes in the morphology and motility of these organisms, and of the related organism Desulphovibrio orientis , brought about by culture in media containing tannins are reported.
