    Abstract: Cellulose-containing fabric is desized by treating with an enzyme hybrid having a catalytically active amino acid sequence of an enzyme such as a lipase or an amylase linked to an amino acid sequence containing a cellulose-binding domain. The enzyme amino acid sequence may be of an .alpha.-amylase obtainable from a species of Bacillus such as Bacillus licheniformis, or of a lipase obtainable from a species of Humicola, Candida, Pseudomonas or Bacillus. The cellulose-binding domain may be from a cellulase, a xylanase, a mannanase, an arabinofuranosidase, an acetylesterase or a chitinase. The enzyme hybrid is obtained from a transformed host cell containing an expression cassette having a DNA sequence encoding the enzyme hybrid. A desizing composition is formed containing the enzyme hybrid and a wetting agent.

    Abstract: There are disclosed graft polyesters useful as adhesives and coatings and especially useful in processes for sizing spun and continuous filament synthetic organic and inorganic fibrous yarn. One embodiment of the invention is a textile size composition having free carboxyl groups which is prepared in situ on a textile yarn by the application of heat or radiation to a mixture of an unsaturated polyester reactant and a monovinyl monomer reactant comprising an acidic monovinyl monomer having at least one carboxyl group or mixtures thereof with any monovinyl monomer. Desizing can be accomplished by partial neutralization of the size to a pH of at least 6 by reacting the size with a base to render the graft polyester water-dispersible or water-soluble.The graft polyester compositions of the invention are especially useful as size compositions since they can be applied to the yarn from a solventless mixture and require only at least one of the application of heat or irradiation to graft polymerize the size in situ on the yarn. The graft polyester of the invention comprises the reaction product of (1) an unsaturated polyester which is the reaction product of at least one polycarboxylic acid reactant, preferably a dicarboxylic acid reactant and at least one polyhydric alcohol reactant, preferably a diol, wherein a minor effective proportion of at least one of said reactants is .alpha.,.beta.-ethylenically unsaturated with (2) at least one monovinyl monomer reactant comprising at least one acidic monovinyl monomer containing at least one carboxyl group or a mixture of said vinyl monomer with any monovinyl monomer.Alternatively, where water-insolubility is desired in the graft polyester under both acid and basic conditions, a polyunsaturated vinyl monomer is utilized having two or more vinyl groups per molecule. The graft polyesters of the invention prepared using monovinyl monomers also can be reacted with cross-linking resins, such as aminoplast resins, to confer water-insolubility under both basic and acid conditions.

    Abstract: A fungal alpha-amylase is provided from Aspergillus terreus (AtAmyl). AtAmyl has an optimal pH of 4.5 and is operable at 30 75 degrees C., allowing the enzyme to be used in combination with a glucoamylase and a pullulanase in a saccharification reaction. This obviates the necessity of running a saccharification reaction as a batch process, where the pH and temperature must be readjusted for optimal use of the alpha-amylase or glucoamylase. AtAmyl also catalyzes the saccharification of starch substrates to an oligosaccharide composition significantly enriched in DP2 and (DP1+DP2) compared to the products of saccharification catalyzed by an alpha-amylase from Aspergillus kawachii. This facilitates the utilization of the oligosaccharide composition by a fermenting organism in a simultaneous saccharification and fermentation process, for example.

    Abstract translation: 由Aspergillus terreus(AtAmyl)提供真菌α-淀粉酶。 AtAmyl具有4.5的最佳pH,并且在30±75℃下可操作,使酶在糖化反应中与葡糖淀粉酶和支链淀粉酶组合使用。 这消除了作为分批方法进行糖化反应的必要性,其中必须重新调节pH和温度以最佳地使用α-淀粉酶或葡糖淀粉酶。 与由来自曲霉(Aspergillus kawachii)的α-淀粉酶催化的糖化产物相比,AtAmyl还催化淀粉底物对显着富含DP2和(DP1 + DP2)的寡糖组合物的糖化。 这有助于例如在同时糖化和发酵过程中由发酵生物体利用寡糖组合物。

    Abstract: A process is provided for manufacturing a high quality cloth having a width of 150 cm or any width in which likelihood of occurrence of defects such as color shading, rub marks, wrinkles and creases due to fabric dyeing method is eliminated and color fastness is enhanced.A process for manufacturing a woven or knit fabric using yarn dyed silk comprises the steps of dyeing (step 3) sericin which covers the periphery of silk fibers and fibroin which is located inside thereof into the same color; making yarn dyed silk (step 4, 5) by doubling and twisting the dyed silk fibers; making a cloth (step 6) by weaving or knitting the yarn dyed silk; swelling (step 7) the yarn dyed silk which constitutes the cloth by dipping the cloth into hot water in a tub; and decomposing (step 8) sericin of the yarn dyed silk of the cloth with an enzyme in hot water in a tub.
