A grass + fishmeal ruminant feed was incubated for 7 d in a mineral salts medium with the non-proteolytic rumen bacteria Bacteroides succinogenes, Ruminococcus flavefaciens, Megasphaera elsdenii and proteolytic strains of Bacteroides ruminicola, Selenomonas ruminantium and Streptococcus bovis in the presence and absence of the anaerobic fungus Neocallitnastix frontalis. The fungus increased the dry matter digestion from 65·0 to 69·4%, and more than doubled the proteolytic activity of the culture filtrate. However, a greater difference was observed with the solid material, where the proteolytic activity increased from 0·71 to 6·89 mg 14C-casein hydrolysed/g/h, due mainly to EDTA-sensitive fungal protease.
