Abstract:
:An anaerobic, cellulose-degrading, gram-negative rod and a gram-positive coccus, identified as Bacteroides succinogenes and Ruminococcus flavefaciens, respectively, were isolated from pig fecal samples. These organisms were isolated from cellulolytic most-probable-number dilutions which represented 4 or 6% of the viable bacterial count when pigs were fed a low- or high-fiber diet, respectively.
