p-Coumaroyl and feruloyl arabinoxylans from plant cell walls as substrates for ruminal bacteria.
Growth of the ruminal bacteria Ruminococcus flavefaciens FD1, Selenomonas ruminantium HD4, and Butyrivibrio fibrisolvens 49 was limited by ester-linked feruloyl and p-coumaroyl groups. The limitation of growth on phenolic acid-carbohydrate complexes varied with individual bacteria and appeared to be influenced by ability to hydrolyze carbohydrate linkages.
