Process of enzymatic conversion.

摘要

A process for enzymatically converting a polysaccharide to a monosaccharide or to one or more polysaccharides of lower molecular weight than the starting polysaccharide comprises contacting the polysaccharide at a pH of from 4.5 to 8.0 with an enzyme derived from Bacillus megaterium which exhibits alph-amylase activity. Preferably, the enzyme is derived from the strain of Bacillus megaterium deposited at the National Collection for Industrial Bacteria (NCIB) under the number 11568. Examples of polysaccharides which can be enzymatically converted according to this process includes starch, partial starch hydrolysates, pullulan and cyclodextrins.
