Starch digestion and adsorption by beta-amylase of Emericella nidulans (Aspergillus nidulans).
A mutant strain of Emericella nidulans MNU 82 was isolated by multistep mutation. The beta-amylase produced by the mutant was able to digest raw starch. It was readily and strongly adsorbed onto raw starch at pH 5.0. The enzyme to starch ratio was 1950 U/g starch. The enzyme showed no correlation between the capacity of raw starch digestion and adsorption of the enzyme.
