Degradation and Utilization of Isolated Hemicellulose by Pure Cultures of Cellulolytic Rumen Bacteria.
Dehority, B. A. (Ohio Agricultural Experiment Station, Wooster). Degradation and utilization of isolated hemicellulose by pure cultures of cellulolytic rumen bacteria. J. 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...
متن کاملThe 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...
متن کاملCharacterization of Cellulolytic and Xylanolytic Enzymes of Bacillus licheniformis JK7 Isolated from the Rumen of a Native Korean Goat
A facultative bacterium producing cellulolytic and hemicellulolytic enzymes was isolated from the rumen of a native Korean goat. The bacterium was identified as a Bacillus licheniformis on the basis of biochemical and morphological characteristics and 16S rDNA sequences, and has been designated Bacillus licheniformis JK7. Endoglucanase activities were higher than those of β-glucosidase and xyla...
متن کاملAn isolated cellulolytic Escherichia coli from bovine rumen produces ethanol and hydrogen from corn straw
BACKGROUND Lignocellulosic biomass is the most abundant resource on earth. Lignocellulose is mainly composed of cellulose, hemicelluloses, and lignin. The special construction of three kinds of constituents led to the prevention of effective degradation. The goal of this work was to investigate the great potentials of bovine rumen for novel cellulolytic bacterial isolation, which may be used fo...
متن کاملQuantitative 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....
