A carbohydrate polymer such as starch and/or cellulose is converted to ethanol by a process in which an aqueous slurry of the carbohydrate polymer acid hydrolyzed to provide a sterile fermentable sugar solution is thereafter continuously converted by fermentation to dilute aqueous ethanol ("beer") i ...

William A Farone, John E Cuzens: Method of separating acids and sugars using ion resin separation. Arkenol, Knobbe Olson & Bear Martens, October 13, 1998: US05820687 (27 worldwide citation)

A economically viable method for producing sugars using concentrated acid hydrolysis of biomass containing cellulose and hemicellulose is disclosed. The cellulose and hemicellulose in the biomass is first decrystallized and then hydrolyzed to produce a hydrolysate containing both sugars and acid. Si ...

Antibiotic A-4696 pseudo-aglycone, produced by mild acid hydrolysis of the actaplanin antibiotic A-4696 complex, has antibacterial and growth promotant activity.

Grund Alan D, Jerrell Thomas A Jr: Deacetylation of n-acetylglucosamine. Bio Technical Resources, TRAVER Robert D, June 23, 2005: WO/2005/056525 (27 worldwide citation)

The invention provides methods of deacetylating N-acetylglucosamine by solid acid hydrolysis on a cation exchange resin. These methods advantageously reduce the amount of acid used and the need for acid recycle facilities. The isolated glucosamine salt produced is very clean, reducing or eliminating ...

Donald B Thompson, Jorge Brumovsky: Manufacture of boiling-stable granular resistant starch by acid hydrolysis and hydrothermal treatment. The Penn State Research Foundation, McKee Voorhees Sease, October 22, 2002: US06468355 (26 worldwide citation)

The invention discloses a boiling-stable granular resistant starch product which may comprise over 60% resistant starch as determined by the TDF method. The starch is made by subjecting a starch source to acid hydrolysis, followed by a hydrothermal treatment which is preferably heat-moisture treatme ...
