Procédé de production d'éthanol à partir de matières premières qui contiennent des sucres fermentables ou des constituants qui peuvent être convertis en sucres, consistant (a) à liquéfier les matières premières en présence d'une alpha-amylase pour obtenir une bouillie liquéfiée, (b) à saccharifier ladite bouillie liquéfiée en présence d'une glucoamylase pour obtenir de l'amidon et des sucres hydrolysés, (c) à faire fermenter l'amidon et les sucres hydrolysés à l'aide de levure pour obtenir de l'éthanol et (d) à recueillir l'éthanol ainsi obtenu, une protéase fongique étant ajoutée à la bouillie liquéfiée pendant la saccharification et/ou à l'amidon et aux sucres hydrolysés pendant la fermentation. Ladite invention décrit également une composition contenant une glucoamylase et une protéase fongique acide.
摘要:
A highly purified alkaline protease preparation is produced by separating a mixture containing amorphous form and crystalline form of alkaline protease from ultrafiltrate containing impurities, through a method which includes the incubation of an aqueous alkaline protease concentrate with sodium chloride and carbohydrate hydrolyse enzymes at an elevated temperature greater than 20 °C and a pH between pH 4.0 and pH 6.5 at constant agitation.
摘要:
Prophylactic and therapeutic agents for the prevention and treatment of viral-induced tumors and, in particular, compositions derived from an Aspergillus fermentation extract, and the use thereof, either directly or to prepare a medicament, for the prevention and treatment of viral-induced tumors in mammals. Such tumors include papilloma-induced tumors. The composition is topically administered.

An enzyme composition, use thereof in a method for reducing the stickiness of honeydew contaminated cotton is disclosed. The composition includes, and the method uses, enzymes such as transglucosidases and pectinases capable of hydrolyzing sugars that make-up honeydew, which are derived from fungal sources, such as fungi of the genus Aspergillus .
摘要:
The present invention relates to a method for the preparation of a purified amylase recovered from a fermentation broth, comprising the addition of a precipitation agent which is a halide salt, most preferably sodium or potassium chloride. According to a preferred embodiment, a further precipitation agent is added which is an organic compound, most preferably an alkyl ester of 4-hydroxybenzoic acid. The present invention also relates to the purified amylases so obtained and to the uses of these purified amylases.
