| 摘要 |
Cellulase, produced by propagating Trichoderma, Myrothrecium Penicillium, Aspergillus or Actinomycetes microorganisms, particularly Trichoderma viridae, on steam-sterilized wet bran or an aqueous culture medium, is used, in the form of an aqueous solution having a pH between 3.5 and 6.5 for removing seed coats from soyabeans (see Division A2). The aqueous solution of cellulase may have a potency of 40 units per ml., and may be the aqueous cultured medium itself, a filtrate thereof, an aqueous extract from said cultured bran, or a solution of dry, refined cellulose (precipitated from the extract and having a potency of 4000 units per gm.) in an aqueous sodium acetate-acetic acid buffer mixture. Pectinase may be added to the said aqueous solution. |
