摘要:
The xylanase is characterized by several partial amino acid sequences and is immunoreactive with an antibody raised against a purified xylanase derived from Humicola insolens, DSM 1800. This xylanase preparation is practically free of cellulase xylanase and is well suited for treatment of paper pulp, as a baking agent and as an additive to fodder.

摘要:
Hydrolysis of plant kingdom polysaccharides by treatment with SPS-ase preparations.SPS-ase is an enzyme adapted to hydrolyzing the water-soluble protein binding polysaccharide present in soy flour decomposed by use of conventional pectinases, which polysaccharide is believed to be widespread in plant kingdom substances. Treatment with an SPS-ase preparation can clarify juices, wines and beers, hydrolyze process wastes such as sugar beet pulp, pomace, and soy milk remanence, improve the digestability of silage, and reduce the viscosity of wort.
