Abstract: A method for recovering inorganic salt during processing of a lignocellulosic feedstock is provided. The method comprises pretreating the lignocellulosic feedstock by adding an acid to the feedstock to produce a pretreated lignocellulosic feedstock. A soluble base is then added to the pretreated lignocellulosic feedstock to adjust the pH and produce a neutralized feedstock. The neutralized feedstock is then enzymatically hydrolyzed to produce an enzyme hydrolyzed feedstock and a sugar stream. Inorganic salt is recovered from either a stream obtained from the lignocellulosic feedstock prior to the step of pretreating, a stream obtained from the pretreated lignocellulosic feedstock, a stream obtained from the neutralized feedstock, a stream obtained from the sugar stream, or a combination of these streams. The inorganic salt may be concentrated, clarified, recovered and purified by crystallization, electrodialysis drying, or agglomeration and granulation, and then used as desired, for example as a fertilizer.

Abstract: A method to control the distribution of the starch sugar's molecular weight by controlling of Ultra-low DE value during the reaction was invented. The method comprising blending starch with water to get starch slurry, and then mixing it with the 0.01%-0.03% of CaCl2 based on dried starch. The next step involves adjusting the pH of the starch slurry. A further step involves adding 0.03%-0.08% of heat-resisting ?-amylases based on dried starch to the starch slurry described above. A further step involves controlling the production under optimal reaction conditions.

Abstract: A delivery system that includes a bone growth promoting material encapsulated within a water absorptive gelatinizable covering is used to promote bone growth in order to repair a bone defect and/or strengthen a weakened bone region. The delivery system may be shaped and sized in order to fit within a bleeding wound (e.g. one that is formed in the gingiva when a tooth is extracted). The covering may be formed of a gelatinizable gauze that forms a gel-like material when moistened with water. The delivery system is contained within a moisture resistant package prior to use. Alternatively, the delivery system comprises a bone growth promoting material and thickening agent contained within a syringe that, upon adding water, form a viscous gel or stiff putty.

Abstract: The present invention describes a process for the preparation of an enzyme-containing granulate wherein an aqueous enzyme-containing liquid is, optionally supplemented with a solid carrier and/or additive ingredients, processed into granules, dried and subsequently coated with a polyolefin, preferably polypropylene and/or polyethylene. This coated enzyme granulate is suitable for the manufacture of animal feed compositions by mixing the granulate with feed ingredients, treating with steam and pelleting. The coated granulates show high enzyme stability during pelleting conditions and during storage. At the same time, the dissolution time of the granule is very short so that the bioavailability of the enzyme to the animal is improved.

Abstract: This invention is directed towards a method of using visible light at wavelengths of at least 500 nm and above in combination with a sensitizer having a flavin moiety to reduce any pathogens that may be contained in blood and blood components. By exposing the blood and blood components to light of 500 nm and higher, only the sensitizer that is bound to nucleic acids of the pathogens will be activated, thus destroying the sensitizer-pathogenic nucleic acid complex. Because unbound sensitizer is not activated at this wavelength, damage to blood and blood components caused by photolysis of unbound sensitizer may be avoided.
