Fig. 4From: Directly mining a fungal thermostable α-amylase from Chinese Nong-flavor liquor starterKinetics hydrolysis of NFAmy13A on starch substrates. The purified NFAmy13A (20 nM) was incubated with different concentrations (0.1–18 mg/ml) of starch substrates, i.e., amylopectin, amylose, potato starch, corn starch or wheat starch, for 30 min in the presence of 10 mM CaCl2Back to article page
