Journal ArticleDOI
Degradation of Protein and Utilization of the Hydrolytic Products by a Predominant Ruminal Bacterium, Prevotella ruminicola B14
TL;DR: It is suggested that P. ruminicola may have a greater impact on peptide degradation than on protein degradation in the rumen, and proteinaceous N sources produced faster growth rates than did NH4Cl, but ammonium chloride produced a greater maximum cell density.
Journal ArticleDOI
Proteome specialization of anaerobic fungi during ruminal degradation of recalcitrant plant fiber
Live Heldal Hagen,Charles G. Brooke,Claire Shaw,Angela D. Norbeck,Hailan Piao,Magnus Ø. Arntzen,Heather M. Olson,Alex Copeland,Nancy G. Isern,Anil K. Shukla,Simon Roux,Vincent Lombard,Vincent Lombard,Bernard Henrissat,Bernard Henrissat,Bernard Henrissat,Michelle A. O’Malley,Igor V. Grigoriev,Igor V. Grigoriev,Susannah G. Tringe,Roderick I. Mackie,Ljiljana Paša-Tolić,Phillip B. Pope,Matthias Hess +23 more
TL;DR: These findings elucidate the intricate networks of in situ recalcitrant fiber deconstruction, and suggest that the anaerobic rumen fungi contribute a specific set of CAZymes that complement the enzyme repertoire provided by the specialized plant cell wall degrading rumen bacteria.
Journal ArticleDOI
Molecular and Biochemical Analyses of the GH44 Module of CbMan5B/Cel44A, a Bifunctional Enzyme from the Hyperthermophilic Bacterium Caldicellulosiruptor bescii
Libin Ye,Su Xiaoyun,George E. Schmitz,Young Hwan Moon,Jing Zhang,Roderick I. Mackie,Isaac Cann +6 more
TL;DR: A model for cellulose hydrolysis and utilization by C. bescii led to modest synergistic activities during degradation of cellulose, and based on the results, it is proposed that the β-sandwich domain is essential for proper folding of the polypeptide.
Journal ArticleDOI
3-phenylpropanoic acid improves the affinity of Ruminococcus albus for cellulose in continuous culture
TL;DR: The contention that PPA maintains a competitive advantage for R. albus when grown in a dynamic, fiber-rich environment is supported.
Journal ArticleDOI
Fecal microbiota of horses in the clinical setting: Potential effects of penicillin and general anesthesia
Anne Mette R. Grønvold,Trine M. L'Abée-Lund,Eric Strand,Henning Sørum,Anthony C. Yannarell,Roderick I. Mackie +5 more
TL;DR: Monitoring of antimicrobial resistance and changes in predominant fecal populations during penicillin treatment and general anesthesia of horses in the clinical setting indicated that horses have an extremely diverse fecal microbiota, with marked differences between individual horses.
