Abstract

In order to convert starch to the fermentative sugar, the effect of pullulanase on the saccharification of starch and pullulanase was investigated. The optimum pH and temperature for the enzyme activity of the glucoamylase and the crude pullulanase from Klebsiella pneumoniae NFB-320 were shown to be identical as pH 6.0 and 60$\circC, respectively. The crude pullulanase was stable between pH 5.0~6.5, and up to 40$\circC, whereas the glucoamylase was stable between pH 4.0~6.5, and up to 40$\circC. When pullulanase and glucoamylase were engaged together in the sacchrification of starch, saccharification yield was increased by 3.2% than the yield obtained by glucoamylase, alone. And the two enzymes produced sugar from pulltulan 18 times much higher than the single use of pullulanase.
