Oxidation Stability

Oxidation Stability Organism
oxidation with O2 and ferricyanide in absence of reducing components stabilizes, simultaneous presence of H2, NADH and O2 causes irreversible inactivation, half-lives in H2/O2 mixtures: 5% O2, 60 min, 20% O2, 30 min, 50% O2, 12 min Cupriavidus necator
