Abstract
Disinfecting of immobilized enzymes is carried out by contacting the immobilized enzymes with a dilute aqueous solution of at least one substituted diethylenetriamine at a concentration and for a period of time which is sufficient to substantially kill the contaminating microorganisms without significant deleterious effects on the immobilized enzymes. The substituted diethylenetriamine is preferably dioctyldiethylenetriamine or a mixture of dioctyldiethylenetriamine and trioctyldiethylenetriamine.
Claims4
A method for disinfecting immobilized enzymes which comprises contacting the immobilized enzymes with a dilute aqueous solution of at least one substituted diethylenetriamine at a concentration and for a period of time which is sufficient to substantially kill the contaminating microorganisms without significant deleterious effects on the immobilized enzymes, in which the enzymes are selected from the group consisting of lactase and glucose isomerase, the enzymes are immobilized on an inorganic support, and the substituted diethylenetriamine is selected from the group consisting of dioctyldiethylenetriamine and a mixture of dioctyldiethylenetriamine and trioctyldiethylenetriamine.
