Utilization of individual cellodextrins by three predominant ruminal cellulolytic bacteria.

摘要

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 cellodextrins.
