I need to know the concentration of oxygen in air saturated 50mM Tris-HCl
pH7.6 buffer at 25C in order to interpret some oxygen electrode data on
the use of O2 by a Rhodococcus aromatic degradative pathway. Does anyone
have a value (preferably with reference) for this? I think the effect of
salts on solubilities at low concentrations may be additive so I guess
values for different concentrations could be scaled to 50mM?
