Microorganisms that were
isolated from the rumen of three different ruminants (cow,
sheep, and goat) include Pseudomonas aeruginosa
(9.0%), Bacillus (37.8%), Micrococcus (8.1%)
and Streptococcus (44.3%) species for bacteria, while
the fungi isolated were species of Fusarium (21.2%),
Penicillium (23.4%), Aspergillus (14.7%) and
Mucor (40.6%). These organisms were later examined
for their ability to hydrolyze cellulose. The results
revealed that P. aeruginosa, Streptococcus,
Bacillus, Penicillin, Aspergillus, Mucor and Fusarium
species were able to hydrolyze cellulose. The study suggests
that the rumen of ruminants harbors various microorganisms
that are active in cellulose breakdown.
