Enhanced removal and/or control of adhesives or sticky materials, “stickies”, from recovered paper stock or virgin pulp fibers is achieved using a combination of enzyme treatment with adsorbents and/or absorbents. Pulp stock to be treated is typically obtained from old magazines, newspapers, household waste, but may include corrugated boxes and office waste. Virgin pulps may include mechanical, chemical, or semi-chemical pulps. Enzymes typically include hydrolases such as cellulases, hemicellulases, pectinases, amylases, and lipases such as esterases, lyases such as pectate lyases, and oxidoreductases. Adsorbents include activated bentonite, microparticles, talc, clay and modified silica. Absorbents typically include water soluble polymers, dispersants, coagulatants and agglomerants.

This invention relates to amylase polypeptides, and nucleic acids encoding the polpypeptides and uses thereof. The amylases of the present invention have been engineered to have more beneficial qualities. Specifically, the amylases of the current invention show an altered thermostability.

The invention discloses a method for extracting fruit dreg dietary fiber through high-pressure microfluidization ultramicro crushing and enzymolysis coupling and belongs to the technical field of agricultural and sideline product waste deep processing. According to the method, water is added into peach dreg for dispersing the peach dreg, the pH is regulated, high-temperature-resistance alpha-amylase and protease are respectively used for enzymolysis for eliminating starch and protein, the peach dreg subjected to the enzymolysis is treated by a high-speed shearing instrument and is subjected to high-pressure microfluidization ultramicro crushing, then, cellulose is added for enzymolysis and centrifugation, filter liquid after enzymolysis and precipitates after enzymolysis are respectively obtained, the filter liquid is subjected to concentration, ethanol precipitation and vacuum drying to obtain high-activity water-soluble dietary fiber, and the precipitates are subjected to water washing and vacuum drying to obtain high-purity insoluble dietary fiber. Waste fruit dreg after the juice squeezing is utilized as raw materials, the fine and deep processing of agricultural and sideline products is realized, and the resource waste is reduced.

The present invention relates to a method for extracting the purificatory cordycepin and the cordyceps amylase from the cordyceps militaris, belonging to the fields of medicines and health protection and chemical engineering. The cordyceps militaris powder is extracted and filtrated by a cooling seep method, the filter residue is mixed with ethanol, the supersonic wave assists to extract and offcenter, the supernatant has the processes of concentration and alcohol-precipitating, then the alcohol-precipitated supernatant has the processes of decompression, concentration and elution, the eluted liquid has the processes of concentration and crystallization and recrystallization using the n-butyl alcohol, at last the purificatory amylase is obtained after freezing and drying. The preparation progress of the present invention only uses water and ethanol as the solvent, thus reducing the pollution, the resin is capable of being reused a plurality of times with low cost. The present invention fully exploits the biological activity ingredients of the cordyceps militaris, realizes the coextraction of the cordycepin and the cordyceps amylase, guarantees the biological activities of the cordycepin and the cordyceps amylase, farthest increases the utilization rate of the raw material to the largest extent, reduces the manufacturing cost. The present invention is suitable for the large-scale industrialized manufacture.

The invention discloses a nutritional compound enzyme used for crops, and the application thereof. The nutritional compound enzyme comprises proteases, phytase, amylases, cellulase enzymes and pectinase, and the like, is a compound formula of a plurality of enzyme preparations, can replace a plant growth promoter and improve soil texture, can provide nutritional substances, such as nitrogen sources and phosphorus and the like, for the counterbalanced growth of crops, lead the crops to become strong and absorb sufficient nutrient at the later growth stage, can improve the resistance against diseases of the crops, is beneficial to the growth and maturation of the crops and improves the output of the crops; the nutritional compound enzyme can convert cellulose into a part of oligosaccharides for improving the immunity of the crops and increasing the chlorophyll content of functional leaves of the crops, thereby improving the quality and output of the crops. The nutritional compound enzyme brings significant economic benefits for peasants.

The invention relates to a multienzyme microorganism and plant growth promotion additive. An active regulator containing multienzyme microorganism and leavening, amylase, protease, cellulose, pectase and polyase are used as base stocks, are added with chitin, various elements and vitamins in micro quantity, amino acid and are added with a microorganism and leavening inoculum Em bacterial solution, are mixed and are fermented to prepare the multienzyme microorganism and plant growth promotion additive.

The invention discloses a method of increasing the content of resistant starch in rice through genome editing and sgRNA special for the same. The method provides a method of increasing the content of resistant starch and/or amylase in rice seeds. The method includes the following steps that expression of SBEIIb genes in the rice is inhibited; the SBEIIb genes are genes of encoding SBEIIb protein. The invention further provides a method of increasing the content of resistant starch in rice and includes the step of inhibiting the activity of the SBEIIb protein in the rice. By using the CRISPR/Cas9 technology, the rice SBEIIb genes are edited at fixed points, the rice SBEIIb genes are knocked off by causing frameshift mutation, and the new generation of new rice germplasm with the content of amylase and resistant starch obviously increased is obtained.
