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...

Degradation and Utilization of Isolated Hemicellulose by Pure Cultures of Cellulolytic Rumen Bacteria.

Bacteriol. 89:1515-1520. 1965.-Hemicelluloses isolated from flax, corn hulls, alfalfa, oat hulls, and fescue grass were used as sole energy sources to study the ability of pure cultures of cellulolytic rumen bacteria to degrad...

Quantitative analysis of cellulose degradation and growth of cellulolytic bacteria in the rumen.

Ruminant animals digest cellulose via a symbiotic relationship with ruminal microorganisms. Because feedstuffs only remain in the rumen for a short time, the rate of cellulose digestion must be very rapid. This speed is facilitated by rumination, a process that returns food to the mouth to be rechewed. By decreasing particle size, the cellulose surface area can be increased by up to 10(6)-fold....
