Sannoju Mukai
Sannoju Mukai (1898 - 1963) was a Japanese biochemist,  
emeritus professor at faculty of technology, Kumamoto University, and a professor of Keijo University. He is also father of Jun-Ichiro Mukai. Academic works 
Mukai made a contribution in Enzyme Chemistry by "On the activation of castor lipase by acids and the ps curve of its action." According to Chemisches Zentralblatt (1929 Band I, Nr.8, 20 Februar), 
"The optimum effect of the castor lipase is not only dependent on the pH in the Rk. dependent on Mg. Vf. tried the Mg-Verbb. can be removed by treating with H2S04 (75 ccm 0.0.5-n. H2S04, 10g castor oil powder, 30 min. ), washing out and drying for four days. The optimal working conditions were then found at pH = 5.62. -— In the case of unsuccessful attempts, dio Mg-Verb. with pepsin or trypsin, activation of lipase by pepsin has been observed. (Journ. Soc. chem. Ind., Japan [Suppl.] 31. 185 B. 1928. Kyushu, Imp. Univ.) "
