    摘要: An isolated alkaline pullulanase Y having .alpha.-amylase activity; a microorganism producing the alkaline pullulanase Y; and a process for producing the alkaline pullulanase Y are disclosed. The alkaline pullulanase Y having .alpha.-amylase activity has its optimum pH at higher alkaline range than conventional alkaline pullulanases and exhibits excellent stability in a wide pH range. Further, the alkaline pullulanase Y has strong resistance to almost all detergent components such as surfactants, chelating agents, proteases for detergents, and the like. Thus the alkaline pullulanase Y can advantageously be used as a detergent component.

    摘要: A novel alkaline pullulanase; a microorganism producing the alkaline pullulanase; and a process for producing the alkaline pullulanase are disclosed. The alkaline pullulanase of the present invention has a higher optimum pH range (pH 9.5-11) than conventional alkaline pullulanases and shows excellent stability in a wider pH range. It has also an optimum temperature of higher than 50.degree. C. and is thermally stable up to 40.degree. C. The alkaline pullulanase has also strong reistance to almost all detergent components such as surfactants, chelating agents, proteases for detergents, and the like. The alkaline pullulanase can advantageously be used as a detergent component. Also, it can be utilized for producing many kinds of oligosaccharides and also together with .alpha.-amylase for producing various monosaccharides.
