✦ Synopsis


Three procedures were employed to identify salt hydrates which were efficient water donors to dry tyrosinase suspended in a substrate solution in chloroform or toluene. Three salts (Na2SOa'10HEO, Na2HPOa'12H20 and Na2CO3"10H20) were effective activators Whereas eleven others were ineffective. It was concluded that the thermodynamic water activity (aw) of the hydrate was the major determinant controlling enzyme activity.
