Screening of polysaccharides for preparation of α-amylase conjugate to enhance stability and storage life

► Screening of polysaccharides for conjugation of α-amylase to enhance stability. ► Conjugation of α-amylase with dextran showed best thermal and pH stability. ► Dextran conjugate showed antimicrobial activity against challenged/added organism. ► Dextran conjugate suppressed aerobic flora in liquid formulation of α-amylase.
