摘要：
A novel thermostable pullulanase having an operating temperature in the range of about 0 to about 75°C, and an operating pH in the range of about 2.5 to 10 is obtained by culturing a strain of Klebsiella pneumoniae capable of producing thermostable pullulanase in a culture medium containing a polysaccharide of starch origin and collecting the enzyme from the fermentatively workd culture medium.
