Summary
A stable enrichment of bacteria capable of metabolizing lactate under methanogenic conditions was obtained from rumen contents. The methanogenic strains associated with lactate utilizers were identified asMethanosarcina sp. andMethanobacterium sp. The role of propionate as indicator of failure in the methanogenic phase is shown.
Résumé
Un enrichissement stable de bactéries capables de métaboliser le lactate dans des conditions méthanigènes a été isolé du contenu de rumen. Les souches méthanigènes, associées avec les utilisateurs de lactate, ont été identifiées comme appartenant aux genresMethanosarcina etMethanobacterium. Le rôle du propionate comme indicateur de la faillite de la phase méthanigène a été démontré.
