Use of chitinase to assess ruminal fungi associated with plant residues in vitro.
Treatment of fibrous residue from in vitro digestion trials with chitinase was evaluated gravimetrically and microscopically to determine the associated fungal biomass. The percent dry weight removed by chitinase with time paralleled changes in the number of sporangia associated with leaves. The fungal biomass contributed about 12% dry matter to the residue of leaves incubated with ruminal fluid plus streptomycin and penicillin.
