Addition of cellulolytic clostridia to the bovine rumen and pig intestinal tract

Experimental studies to identify conditions to introduce intestinal cellulolytic bacteria into bovine rumen and pig large intestine reveal that a competition should be overcome for efficient introduction of these organisms into an intestinal ecosystem. In bovine rumen Clostridium longisporum exists as a transient organism, while C. herbivorans is part of the pig large intestine.
