A starch removal method from a wheat bran medium was
established using citric acid. Secreted enzymes from cultivated
A. oryzae RIB40 were then investigated. The specific activity of
α-amylase decreased while that of xylanase and xylosidase
increased 2-fold and 7-fold, respectively. Proteomics analysis
identified three new α-glucosidases and two new α-glucanases.
DNA microarray identified high expression of three new endo
glucanases and one α-xylosidase. The expression of β-1,4
xylanase was increased 27-fold.
