An acid recovery system used in a hydrolysis operation includes a chromatographic unit to provide initial separation of sugar and acid. The sugar product provided by the chromatographic unit is processed to produce higher value products, such as ethanol. The remaining acid is contaminated by sugar. A nanofiltration unit containing a nanofilter membrane processes the sugar contaminated acid. The acid is allowed to permeate across the nanofilter membrane while sugar is rejected. The permeate is provided to a conventional acid recovery system and recycled for use in the hydrolysis process.

The present invention is directed to a method comprising a multistep process for recovering one or more monosaccharides from a solution containing at least two monosaccharides selected from the group consisting of rhamnose, arabinose, xylose and mixtures thereof by using chromatographic separation comprising at least one step, where a weak acid cation exchange resin is used for the chromatographic separation.

The present invention relates to methods for converting plant cell wall polysaccharides into one or more products, comprising: treating the plant cell wall polysaccharides with an effective amount of a spent whole fermentation broth of a recombinant microorganism, wherein the recombinant microorganism expresses one or more heterologous genes encoding enzymes which degrade or convert the plant cell wall polysaccharides into the one or more products. The present invention also relates to methods for producing an organic substance, comprising: (a) saccharifying plant cell wall polysaccharides with an effective amount of a spent whole fermentation broth of a recombinant microorganism, wherein the recombinant microorganism expresses one or more heterologous genes encoding enzymes which degrade or convert the plant cell wall polysaccharides into saccharified material; (b) fermenting the saccharified material of step (a) with one or more fermenting microoganisms; and (c) recovering the organic substance from the fermentation.

To achieve efficient use of enzyme in obtaining a sugar solution through a reaction of the enzyme and biomass containing cellulose. In obtaining a sugar solution through a reaction of enzyme and biomass containing cellulose, the biomass and the enzyme are caused to react in a first reaction tank, whereby a sugar solution in which the enzyme is dispersed and a residue containing the unreached biomass adsorbing the enzyme are generated, these sugar solution and residue are next separated, a pH adjusting solution is supplied to the residue in a second reaction tank to prepare a dilute solution whose sugar concentration is lower than that of the sugar solution, and in this dilute solution, a sugar solution is generated through a reaction between the residue and the enzyme adsorbed to the residue.

The present invention relates to methods of processing lignocellulosic material to obtain hemicellulose sugars, cellulose sugars, lignin, cellulose and other high-value products. Also provided are hemicellulose sugars, cellulose sugars, lignin, cellulose, and other high-value products.

The invention relates to extracts, in particular non-nutrient phytochemicals, form sugar cane or sugar beet waste products, such as molasses, sugar mud and bagasse, which have Glycemic Index (GI) lowering properties and their use as sweeteners and in foods containing sugar.

The present invention provides an apparatus and a method for conversion of cellulosic material, such as chopped straw and corn stover, and household waste, to ethanol and other products. The cellulosic material is subjected to continuous hydrothermal pre-treatment without addition of chemicals, and a liquid and a fibre fraction are produced. The fibre fraction is subjected to enzymatic liquefaction and saccharification. The method of the present invention comprises:performing the hydrothermal pre-treatment by subjecting the cellulosic material to at least one soaking operation, and conveying the cellulosic material through at least one pressurised reactor, and subjecting the cellulosic material to at least one pressing operation, creating a fibre fraction and a liquid fraction;selecting the temperature and residence time for the hydrothermal pretreatment, so that the fibrous structure of the feedstock is maintained and at least 80% of the lignin is maintained in the fibre fraction.

Self-cleaning apparatus and methods are disclosed for handling viscous fluids, such as thick solid-liquid slurries of lignocellulosic biomass and its components, under high pressure, using an array of retractable valves.

A microbial adherence inhibitor specific to lactic acid producing microorganisms, in the form of fowl egg antibodies is disclosed, along with the method of making it and methods of using it. The inhibitor functions by substantially preventing the attachment or adherence of colony-forming immunogens in the rumen and intestinal tracts of host food animals. The inhibitor is made by inoculating female birds with the immunogen, allowing time for an immune response in the female bird and then harvesting the eggs that contain antibodies to the immunogen. The egg contents can be dried or used as a liquid and added to the feed or water for the host animals. Dependent upon the particular immunogen with which the female bird is inoculated, the egg antibody is used to promote the growth of food animals by improving feed conversion rates by decreasing the lactic acid production caused by the presence of certain colony-forming organisms in the animals, and to substantially reduce or eliminate the incidence of species that have been linked to very high production of lactic acid which can result in reduced performance and in acute situations, dangerously low rumen pH levels. When high levels of lactic acid are present in the rumen, rumen ulcers can form. When rumen ulcers are present other bacteria such as Fusobacterium necrophorum can escape the rumen and cause liver abscesses or laminitis, which further reduce feed conversion efficiency. Colony forming immunogens such as Streptococcus bovis (a major lactic acid producer) and Fusobacterium necrophorum can both be targeted by antibodies to enhance feed efficiency.

The invention discloses a method for extracting sugar from residual sugar liquor in production of preserved fruits. The sugar content of sugar solution, namely a by-product in processing, generated in the production of the preserved fruits reaches 30% to 40%, but in the conventional production process of the preserved fruits, the sugar solution is always abandoned due to the lack of an ideal sugar extraction method. The method comprises the measures of filtration, dilution, enzymolysis, ultrafiltration, decoloration and concentration to extract the sugar from the residual sugar liquor in the production of the preserved fruits; and the sugar degree of obtained syrup reaches 70 degrees Bx, the sugar content of the syrup reaches 70%, and the mixed syrup contains fructose, glucose and sucrose. The method can be used for realizing the comprehensive utilization of the residual sugar liquor in the production of the preserved fruits of preserved fruit production enterprises, reducing the production costs of the preserved fruits, controlling the environment pollution caused by the preserved fruit production enterprises, thus achieving multiple purposes, and serving as a powerful measure for promoting the technical progress of the preserved fruit production enterprises.

A method for pretreating and disrupting cell structure of biomass by subjecting the biomass to high pressure, thereby disrupting the cell structure of the biomass is provided. Also provided is a device for performing the method, wherein the device includes a cavitating device and a cell structure disrupting device disposed within the cavitating device for disrupting the cell structure and exposing the internal cell structure to enzymes.

A system and method for hardwood pulp liquid hydrolysate conditioning includes a first evaporator receives a hardwood mix extract and outputting a quantity of vapor and extract. A hydrolysis unit receives the extract, hydrolyzes and outputs to a lignin separation device, which separates and recovers a quantity of lignin. A neutralization device receives extract from the lignin separation device and a neutralizing agent, producing a mixture of solid precipitate and a fifth extract. The solid precipitate is removed from the fifth extract. A second evaporator removes a quantity of acid from the fifth extract in a vapor form. This vapor may be recycled to improve total acid recovery or discarded. A desalination device receives the diluted extract, separates out some of the acid and salt and outputs a desalinated solution.
