Biography

Zhang Shuzheng, female, Han nationality, is a native of Shulu, Hebei Province. She graduated from Beijing University in 1945.

Zhang Shuzheng spent much of her career analyzing and comparing different kinds of composition of aspergillus amylase series in the alcohol industry. During the early 1950s, she confirmed the superiority of black aspergillus and illustrated the metabolic way of xylose and Arabicose, purified xylitol dehydrogenation enzyme, which proved to be induced enzyme.

Zhang discovered that there was amrita in white mould and illustrated the way in which it was synthesized. She discovered, and purified, NADP-amrita dehydrogenation enzyme and was the first to obtain a crystal of the Red aspergillus saccharification enzyme and she researched its nature, chemical composition, peptide structure, chemical decoration and spectroscopic construction, discovering that there were construction differences that existed among different modular types.

During the 1980s Zhang selected and cultivated mylase high yield bacteria and researched more than 20 series of indican enzyme. She was the first to discover D-Drock alga indican enzyme with strict original specialty and purified 8 enzymes from hot favorable fungi.

Zhang is an academician of the Chinese Academy of Sciences.
