Na-Coupled Respiration and Reshaping of Extracellular Polysaccharide Layer Counteract Monensin-Induced Cation Permeability in B4.

Monensin is an ionophore for monovalent cations, which is frequently used to prevent ketosis and to enhance performance in dairy cows. Studies have shown the rumen bacteria B4 being less affected by monensin. The present study aimed to reveal more information about the respective molecular mechanisms in , as there is still a lack of knowledge about defense mechanisms against monensin.
