8338 results about "Cellulase" patented technology

Cellulase is any of several enzymes produced chiefly by fungi, bacteria, and protozoans that catalyze cellulolysis, the decomposition of cellulose and of some related polysaccharides. The name is also used for any naturally occurring mixture or complex of various such enzymes, that act serially or synergistically to decompose cellulosic material.

Natural vegetable and fruit fermented beverage

The invention discloses a preparation method of a novel vegetable and fruit fermented beverage. The preparation method comprises the steps of: firstly carrying out enzymolysis on mixed fresh juice of fresh vegetables and fruits after dilution and size mixing by adopting cellulase, fermenting by adopting a mixed lactic acid starter after adding sugar and corn oligopeptide as fermentation substrates and sterilizing, adding calcium carbonate when the pH reaches 4.0, and then inoculating leuconostoc mesenteroides for continuous fermentation; adding a feed supplement and sterilizing when the pH reaches 3.5, and then adding high-activity dry yeast for the fermentation for 2-3 days; and finally performing sterilization, centrifugation, homogenizing, blending, sterilizing and filling to obtain the novel vegetable and fruit fermented functional beverage. The enzymolysis is firstly carried out on a product by the cellulase, then lactic acid bacteria and saccharomycetes are utilized for the step-by-step fermentation of the mixed fresh juice of the fresh vegetables and fruits, and the corn oligopeptide is added to promote the growth and the metabolism of fermentation strains, so that the novel vegetable and fruit fermented beverage has clear composition of functional components, contains abundant oligopeptide, organic acids, reducing sugars, sugar alcohols and soluble dietary fiber, and integrates nutrition and health care, thus being a novel vegetable and fruit fermented beverage.

Method of obtaining a product sugar stream from cellulosic biomass

A process for obtaining a product sugar stream from cellulosic biomass is disclosed. In one process, the cellulosic biomass is pretreated at a pH between about 0.4 to 2.0 by adding one or more than one acid to produce a pretreated cellulosic biomass comprising acetic acid. One or more than one base is then added to the pretreated cellulosic biomass to adjust the pretreated cellulosic biomass to a pH of about 4.0 to about 6.0 to produce a neutralized cellulosic biomass comprising inorganic salt and acetate salt. The neutralized biomass is then hydrolyzed by cellulase enzymes to produce a crude sugar stream. Insoluble residue is separated from the crude sugar stream and the resulting clarified sugar stream is treated using ion exclusion chromatography at about pH 5.0 to about 10.0 to produce one or more raffinate streams and a product stream. The raffinate stream comprises inorganic salts and acetate salts, and the product stream comprises sugar. The product stream may then be fermented or otherwise further processed. In an alternate process, a product sugar stream is obtained from a crude sugar stream that is produced from conversion of cellulosic biomass to sugar. The cellulosic biomass may be produced using any suitable method. In this process the crude sugar stream is treated using ion exclusion chromatography at about pH 5.0 to about 10.0 to produce one or more than one raffinate stream comprising sulfate and acetate salts, and a product stream comprising sugar, and the product sugar stream is obtained.

Method of high-efficiency pretreatment on biomass

The invention discloses a method capable of carrying out green high-efficiency hydrolysis pretreatment on lignocellulose biomass. The method in the invention comprises the steps of hydrolyzing the hemicellulose in the cellulose biomass into saccharide products mainly containing xylose and oligose thereof using a two-step temperature-changing segmentation hydrolysis method so as to accomplish the pretreatment, and adding the pretreated solid raw material mainly containing cellulose and lignin to cellulase so as to accomplish enzymatic hydrolysis and recover the saccharide products to the utmost extent. The invention uses high-temperature liquid water as reaction medium, has the advantages that the method has low cost and is environment-friendly and green. The reaction conditions are moderate, the saccharide products are degraded less, and the recovery rate is high. By adopting the two-step temperature-changing segmentation hydrolysis method, the method not only hydrolyzes the hemicellulose to the utmost extent to obtain the saccharide products, but also further pre-treats the raw material such that the cellulose is made into glucose through enzymatic hydrolysis, reaching the purpose of protecting environment and hydrolyzing the lignocellulose biomass highly effectively. The raw material is capable of realizing waste utilization and promotes the development of green industries.
