Abstract
Abstract SPS-A novel pectic-like polysaccharide derived from soy plant cell walls characterized by capability to bind to proteins. SPS-ase-The carbohydrase complex capable of decomposing SPS into decomposition products incapable of attaching to protein, and method for producing SPS-ase by cultivation of an SPS-ase producing microorganism for which preferred microorganism strains are Aspergillus aculeatus CBS 101.43 and Aspergillus japonicus IFO 4408.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
27 words
SPS-ase, a carbohydrase complex capable of decomposing the water soluble polysaccharide component of soy remanence that binds to proteins into decomposition products incapable of attaching to protein.
Claim 2
Dependent Claim
27 words
SPS-ase, a carbohydrase complex capable of decomposing the water soluble polysaccharide component of soy remanence that binds to proteins into decomposition products incapable of attaching to protein.
Claim 3
Dependent Claim
10 words
The SPS-ase of claim 1 produced by Aspergillus aculeatus CBS-101.43.
Claim 4
Dependent Claim
59 words
Method for production of SPS-ase, a carbohydrase complex, capable of decomposing the water soluble polysaccharide component of soy remanence that binds to proteins which comprises cultivating a SPS-ase producing microorganism selected from the group consisting of Aspergillus aculeatus CPS-101.43, Aspergillus japonicus IFO 4408 and mutants thereof in a nutrient medium, followed by recovering the SPS-ase from the cultivation broth.
Claim 5
Dependent Claim
59 words
Method for production of SPS-ase, a carbohydrase complex, capable of decomposing the water soluble polysaccharide component of soy remanence that binds to proteins which comprises cultivating a SPS-ase producing microorganism selected from the group consisting of Aspergillus aculeatus CPS-101.43, Aspergillus japonicus IFO 4408 and mutants thereof in a nutrient medium, followed by recovering the SPS-ase from the cultivation broth.
Claim 6
Dependent Claim
38 words
A method according to claim 3, wherein cultivation is carried out by submerged cultivation at a pH in the range of from 3 to 7, at a temperature in the range of from 20° C. to 40° C.
Claim 7
Dependent Claim
14 words
A method according to claim 3, wherein the nutrient medium contains toasted soy meal.
Claim 8
Dependent Claim
15 words
A method according to claim 5, wherein the soymeal is pre-treated with a proteolytic enzyme.
Claim 9
Dependent Claim
17 words
A method according to claim 3, wherein pectin is added to the nutrient medium during the cultivation.
