Abstract
|
|
|
Kluyveromyces marxinus LG contains an inulase activity which is inducible by growth on inulin. The highest enzyme activity obtained at the initial stage of stationary phase of growth curve.
The partially purified inulase hydrolyzed inulin, sucrose and raffinose. This enzyme showed the maximal activity at pH 4.0 and temperature of 5.5℃ for inulin and sucrose. It was also markedly inhibited by Hg^+ and Ag ^+ but not EDTA. This inulase was charaturized as a undo type which contains invertase activity and Km values for inulin and sucrose were 1.2×10^(-2)M and 1.3×10^(-4)M respectively.
