The hydroxylase and oxidase activities of mushroom tyrosinase were studied in both sodium di-2-ethylhexylsulfosuccinate (AOT)/isooctane and cetyltrimethylammonium bromide (CTAB)/hexane/chloroform reversed micelles. The enzyme presented its highest ac

The water activities (a(w)) of 13 salt hydrate pairs were determined from vapor pressure measurements; a(w) values for a subset were also estimated from a study of water transfer to isopropylether. The application of salt hydrates as water buffers wa

The conversion of o-diphenols to o-quinones was carried out in chloroform using a dry powder prepared from mushrooms as the catalyst. Several salt hydrates proved effective in supplying the small amount of water necessary for catalysis. The efficacy

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 (Na2SO4·10H2O, Na2HPO4·12H2O and Na2CO3·10H2O) were effective acti
