Abstract

Sodium gradients (ΔpNa) were measured in resting cells of Fibrobacter succinogenes by in vivo ²³Na nuclear magnetic resonance using Tm(DOTP)⁵⁻ [thulium(III) 1,4,7,10-tetraazacyclododecane-N′,N′′,N′′′-tetramethylenephosphonate] as the shift reagent. This bacterium was able to maintain a ΔpNa of −55 to −40 mV for extracellular sodium concentrations ranging from 30 to 200 mM. Depletion of Na⁺ ions during the washing steps led to irreversible damage (modification of glucose metabolism and inability to maintain a sodium gradient).
