[Effect of NADH and several Krebs cycle substrates on the endogenous metabolism of Pseudomonas fluorescens (type S)].

Simultaneous addition of succinate (or fumarate) and NADH to a non-proliferating suspension of P. fluorescens results in an enhancement of the oxydation of the endogenous substrates. This conclusion is in accord with the determination of the respiratory and the oxidation quotients of the analysed exogenous substrates.
