Abstract
In order to study the condition of starch hydrolysis with thermostable ?-amylase the influence of the substrate concentration, temperature and pH were investigated. The kinetics parameters ? Km and Vmax were determined using Michaelis ? Menten equation and the other its forms ? Lineweaver - Burk, Hanes - Woolf and Eadie - Hofstee. It was found that reaction rate has maximum value at pH 5.8 and temperature of 75 ºC. The values of Km are between 60.42 ? 65.72?g.ml-1, and Vmax has values be-tween 10.89 and 11.35 ?g.ml-1.min-1.
