additional information modulation of calibration parameters of biosensors, in which glucose oxidase is used for biorecognition, in the presence of different chlorides by following the transient phase dynamics ofoxygen concentration with an oxygen optrode, mechanism, overview. the maximum calculated signal change was amplifiedfor about 20% in the presence of sodium and magnesium chlorides. The value of the kinetic parameter decreases along with the addition of salts and increases only at sodium chloride concentrations over 0.5 mM, MgCl2 causes a 1.3fold essential increase of the maximum signal change parameter A in a salt concentration, ranging from 0.1 to 0.4 M. AlCl3 inhibits the enzyme at 5 mM, and at higher salt concentrations over 0.1 M, the catalytic activity is completely inhibited Aspergillus niger

Inhibitors

Inhibitors Comment Organism Structure
AlCl3 inhibits the enzyme at low concentrations of 5 mM, and inhibits it completely at higher salt concentrations over 0.1 M Aspergillus niger
Mg2+ total inhibition of the enzyme at a Mg2+ concentration of 1.9 M Aspergillus niger
Na+ the inhibiting effect of Na+ions is reduced at Na+concentrations over 0.5 M Aspergillus niger
NaNO3 a competitive inhibitor of glucose oxidase Aspergillus niger
