Study on Curdlan Extraction by Neutral Proteinase on Ferment Liquid

Abstract

Abstract: As the result of orthogonal test,the most rational technologicl factors for extracting Curdlan fromferment liquid by means of the neutral proteinase was determined.It confirmed th at this extracting way was more effic ient than the other ways.The amino acids and nucleic acids of the bacteria were thoroughly removed in the product.The polysaccharine was identified to be theβ-(1,3)polyglucosan with proper molecular structure.

Key words: Curdlan , Proteinase , Extracting , Chro matograph
