The present invention relates to an enzyme blend composition comprising a glucoamylase, an acid stable alpha amylase, and an acid fungal protease. The present invention is further directed to a method for producing end products such as alcohols from fermentable sugars, comprising the steps of: (a) contacting a slurry comprising a milled grain that contains starch with an alpha amylase to produce a liquefact; (b) contacting the liquefact with a glucoamylase, an acid stable alpha amylase, and an acid fungal protease, to produce fermentable sugars; and (c) fermenting the fermentable sugars in the presence of a fermenting organism to produce end products.

Acid-stable proteases of the subtilisin family, their use in animal feed, feed-additives and feed compositions containing such proteases, and methods for the treatment of vegetable proteins using such proteases.

A method is presented for making alkoxy-modified silsesquioxanes (AMS) or co-alkoxy-modified silsesquioxanes (co-AMS,) comprising the steps of (a) combining as a reaction mixture (i) water, (ii) an acid-stable solvent for the water, (iii) a solid strong cationic hydrolysis and condensation catalyst, and (iv) a trialkoxysilane compound, (b) allowing the reaction mixture to react for about 0.5 hours to about 200 hours to form the alkoxy-modified silsesquioxanes; and (c) recovering the alkoxy-modified silsesquioxanes from the reaction mixture. The use of solid strong cationic catalysts in this reaction system is advantageous because they remain as solids throughout the reaction, allowing simplified separation of the solid catalyst from the soluble AMS or co-AMS products, resulting in total or near total recovery of the AMS or co-AMS products, the products being free of, or substantially free of residual acid catalyst, as well as virtual total recovery of the catalyst for recycling. The improved AMS and co-AMS compounds, vulcanizable rubber compounds containing them, and a pneumatic tire having a component made from the vulcanized rubber compounds are also presented.

A positive resist composition comprising: (A) a resin showing an increase in the solubility in an alkali developer by the action of an acid; (B) a compound being capable of generating an acid when irradiated with an actinic ray or a radiation; (C) a resin having a silicon-containing repeating unit of a specific structure and being stable to acids but insoluble in an alkali developer; and (D) a solvent; and a pattern making method using the same.

The invention provides a dietary supplement comprising at least one flavonoid source and an enzyme, that is effective for inhibiting in vivo platelet activity and LDL cholesterol oxidation in a mammal at a dosage of about 30 mg / Kg or less. The supplement may contain flavonoid sources found in grape seed extracts, grape skin extracts, bilberry extracts, ginkgo biloba extracts or the flavonoid quercetin. The supplement may also contain fungal proteases, acid stable proteases and bromelain. The invention further provides a method for using the dietary supplement and an article of manufacture containing the supplement.

A water-soluble acid stable soy protein, methods for making same and acidic food or acidic beverage fortified therewith. Particularly, this invention is useful in the pH range of 3.5 to 4.1 where other soy protein fortification methods do not work. The invention is comprised of a soy protein, a thermal treatment method to solubilize at least 90 % of the protein, an acidification of the protein to a point preferably significantly below the iso-electric value, and a partial neutralization to bring the product proximal to the intended pH of the application it will be used in.
