Chromatographic Separation of Amyloglucosidase From the Mixtures of Enzymes

Abstract

An affinity chromatographic separation of amyloglucosidase (AMG) enzyme using β-cyclodextrin-chitosan matrix was investigated in this study. The adsorbent selectively adsorbed AMG from the mixtures of enzymes (lactase and α-amylase), and this selectively bound AMG was eluted from the column in two steps with a recovery yield of about 72%. A small fraction of AMG and other contaminating proteins did not bind to the column specifically and were eluted easily. Purified AMG was visualised on the sodiumdodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) experiments
