    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 fumigatus (AfAmy1). AfAmy1 has an optimal pH of 3.5 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. AfAmy1 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.
