General Stability

General Stability Organism
albumin, gelatin or surface-active non-ionic substances protect against thermal inactivation or denaturation by air Aspergillus niger
O2 pressures higher than 0.04 atm of O2 accelerate the denaturation of the enzyme even in the presence of o-phenylenediamine Aspergillus niger
p-phenylenediamine, o-diphenols, p-diphenols and p-aromatic diamines protect against thermal inactivation or denaturation by air Aspergillus niger
