Activity of immobilized papain dehydrated by n-propanol in low-water media
A propanol-rinsed enzyme preparations (PREP) of papain showed an activity of 59 nmol min-1 (mg powder)-1 in tert-butanol at the optimal water activity of 0.2. The immobilized papain was stable in aqueous media for 3 d at 4°C. Solid-state buffers (bases and their HCl salts) suspended in the organic m...
