Invited Review: Adhesion Mechanisms of Rumen Cellulolytic Bacteria

Adhesion of cellulolytic ruminal bacteria to barley straw.

Adhesion of the cellulolytic ruminal bacteria Ruminococcus flavefaciens and Fibrobacter succinogenes to barley straw was measured by incubating bacterial suspensions with hammer-milled straw for 30 min, filtering the mixtures through sintered glass filters, and measuring the optical densities of the filtrates. Maximum adhesion of both species occurred at pH 6.0 and during mid- to late-exponenti...

The Cellulolytic Activity of Pure Strains of Bacteria from the Rumen of Cattle.

The in vitro breakdown of degraded and undegraded varieties of cellulose was examined by using pure strains of bacteria isolated from the rumen of cattle. One strain of Bacteroides succinogenes, two strains of Ruminococcus albus and two strains of Ruminococcus jlavefaciens were allowed to ferment ground cellulose powder (prepared from filter paper), cellulose powder (Whatman) and undegraded cot...
