Utilization of individual cellodextrins by three predominant ruminal cellulolytic bacteria.
Growth of the ruminal bacteria Fibrobacter succinogenes S85, Ruminococcus flavefaciens FD-1, and R. albus 7 followed Monod kinetics with respect to concentrations of individual pure cellodextrins (cellobiose, cellotriose, cellotetraose, cellopentaose, and cellohexaose). Under the conditions tested, R. flavefaciens FD-1 possesses the greatest capacity to compete for low concentrations of these c...
متن کاملDifferential fermentation of cellulose allomorphs by ruminal cellulolytic bacteria.
In addition to its usual native crystalline form (cellulose I), cellulose can exist in a variety of alternative crystalline forms (allomorphs) which differ in their unit cell dimensions, chain packing schemes, and hydrogen bonding relationships. We prepared, by various chemical treatments, four different alternative allomorphs, along with an amorphous (noncrystalline) cellulose which retained i...
متن کاملEffects of Methylcellulose on Cellulolytic Bacteria Attachment and Rice Straw Degradation in the In vitro Rumen Fermentation
An in vitro experiment was conducted to evaluate the effect of methylcellulose on the attachment of major cellulolytic bacteria on rice straw and its digestibility. Rice straw was incubated with ruminal mixture with or without 0.1% methylcellulose (MC). The attachment of F. succinogenes, R. flavefaciens and R. albus populations on rice straw was measured using real-time PCR with specific primer...
متن کاملFermentation and aerobic metabolism of cellodextrins by yeasts.
The fermentation and aerobic metabolism of cellodextrins by 14 yeast species or strains was monitored. When grown aerobically, Candida wickerhamii, C. guilliermondii, and C. molischiana metabolized cellodextrins of degree of polymerization 3 to 6. C. wickerhamii and C. molischiana also fermented these substrates, while C. guilliermondii fermented only cellodextrins of degree of polymerization l...

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...
