P. ruminicola is one of the major proteolytic bacteria in the rumen, breaking down protein from feedstuffs and then resynthesizing bacterial protein from ammonia and large peptides. (Image provided from DairyHerd.com)
P. ruminicola contributes significantly to the degradation of starches (such as corn silage and other grains) within the rumen. When cattle are fed grains in a feedlot operation, P. ruminicola plays a large role in the continued health of the animal. (Photo provided by the University of Wisconsin)
Succinate is the major fermentation end-product of P. ruminicola, which will then be utilized to produce the volatile fatty acid propionate, a glucose precursor.
