摘要

The cruce extracts of alpha-amylases when mixed with alginate,tert-butyl alcohol,and ammonium sulfate resulted in an interfactal precipitate contining polymer-bound amylase.The precipitate was dissolved in 1 M maltose to recover alpha-amylase activity The recovery of alpha-amylases were 74% 77% and 92% in the case of Bacillus amyloliquefaciens,wheat germ and porcine pancreas,respecitively.All purified preparations showed a single band on SDS-PAGE
