In 1913 Dr, Kita pointed out a special amylase action in Asp. oryzae which produces glucose abundantly from starch without co-operation of maltase.This action is quite similar to our γ-amylase, but the direct verification of "Kita-anzyme" is very difficult, because the β-amylase fraction of ordinary mold can never be isolated from maltase.We redetected the existence of the "Kita-enzyme", not only in Asp. oryzae but also in Rh. javakicus and Asp. awamori ; however, Asp. kawachii and its "negro parent" are lacked in this special amylase.The "Kita-enzyme" differs from γ-amylase by its aciduric character, then we consider it as aciduric γ-amylase.Our results obtained hitherto on the diastatic enzyme systems of several mclds can be summerized as following table.[numerical formula]
