a Activities of amylolytic enzymes from A. niger CICC2462 and ∆amyR (amyR3, amyR6 and amyR12) strains grown on fermentation medium. b Separation of identified amylolytic enzyme proteins from the fermentation supernatant of A. niger CICC2462 and ∆amyR (amyR3, amyR6 and amyR12) strains by SDS-PAGE. 1, 2 and 3 represent glucoamylase, acid-stable alpha-amylase and alpha-amylase, respectively. An volume of 10 μL of each sample was separated on a 12 % resolving gel. c The protein concentration of A. niger CICC2462 and amyR12 strains
