A note on the fermentation of pectin by pure strains and combined cultures of rumen bacteria. 
Bacteroides ruminicola, pure or combined with Selenomonas ruminantium, and Lachnospira multiparus, pure or combined with Succinivibrio dextrinosolvens, were grown on a medium with pectin as energy source.  There was a difference in fermentation products between the pure and combined cultures and efficiency of substrate utilization was better with the combined cultures.
