The method for extracting pure sugar from agricultural raw materials involves hydrolyzing and removing impurities from the extracted material. This is then fermented with yeast specific to the target sugar to reduce unwanted sugar components, decrease color, and reduce salt content in the extract. Finally, the material is dried. This biological process yields pure sugar as a product, providing a way to process and add value to agricultural raw material extracts.

The system comprises a substrate preparation unit (102), a fermentation bioreactor (104), a product recovery unit (106), and a waste management system (108). The substrate preparation unit (102) processes proteinaceous materials into a form suitable for fermentation. The fermentation bioreactor (104) cultivates Acetoanaerobium sticklandii DSM 519 under anaerobic conditions, facilitating amino acid catabolism. The product recovery unit (106) separates and purifies biofuel components from the fermentation broth. The waste management system (108) handles residual biomass and by-products, ensuring environmentally friendly disposal or reuse. The invention promotes efficient biofuel production from protein-based waste materials, enhancing sustainability and reducing reliance on carbohydrate feedstocks.

A method for obtaining a cellulose preparation from an enzymatic solution clarified by solvent extraction from the incubated yeast cake of an Aspergillus Niger microorganism that produces cellulose, which method comprises the improvement of subjecting the incubated yeast cake before the treatment of solvent extraction to dry for two to four hours at 55-65º C, thus obtaining a decolorized cellulose of high purity and a cellulolytic activity or cleavage of the improved cellulose.

A procedure for removing skins and leathers and for relaxing their fibrous structure, characterized in that the skins or leathers are exposed to the action of chlorine dioxide.

Perfections in depilatory means by extirpation and thermosensitive, characterized by the fact of combining at least two flexible and foldable sheets, applied one on top of the other and held together by the interposition of a layer of adhesive hygienic paste occupying an area of said sheets located inside a peripheral box that leaves a margin free on the edge of each of the sheets, the said paste having a plasticizing or fluidizing principle at a temperature corresponding substantially to the normal temperature of the human body.

In a process for the elimination of volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) formed as by-products in the shift section (SS) of an ammonia plant, a carbon dioxide (C02) stream from a vent line, which is arranged downstream from the shift section and the C02 removal section, is recycled to the primary reformer (TR) of the ammonia plant. This way, the oxygenates contained in the carbon dioxide vent will be decomposed in the primary reformer burners, and the total emission of VOCs and HAPs will be considerably reduced.

The invention provides a process for the removal of sulphides, including hydrogen sulphide, carbonyl sulphide and carbon disulphide, from a gas stream by scrubbing the gas with an aqueous washing liquid and treating the washing liquid with sulphide-oxisising bacteria in the presence of an electron acceptor and reusing the treated liquid as a washing liquid, wherein the scrubbing and the bacterial treatment are carried out in the same reactor and nitrate is used as the electron acceptor. The process is especially uscful for desulphurssing gas at high pressure, such as natural gas.

The present invention relates to the use of glycosyl hydrolase family (61) polypeptides in the presence of celluases for textile manufacture as well as a textile composition comprising glycosyl hydrolase family (61) polypeptides and cellulases.
