Web1 INTRODUCTION. Enzyme stability is greatly influenced by the presence of water (Klibanov, 1989; Zaks and Russel, 1988). For example, the stability of α-amylase dissolved in water is very poor especially in low concentration without buffer. Many researchers focus on the methods that can promote the stability of enzymes. WebAn increase in temperature beyond the optimum causes the enzyme’s active site. to become denatured.
