What is the exact reason why some bacteria with a respiratory chain and
using oxygen as a terminal electron acceptor are oxidase-negative
(e.g. the facultatively anaerobic Enterobacteriaceae, and the obligately aerobic
Gluconobacter, Acetobacter, Acinetobacter spp.). Is it due to the redox potential
of the cytochromes, or to poor uptake of the substrate that is used in the oxidase test?
Thanks for your wisdom
