Embodiment Construction

[0015] A composite preparation of grass fiber bioseparation, which is composed of fungus components and enzyme components. The fungus components include white rot fungi and fermentation bacteria. The fermentation bacteria are C3008C fermentation bacteria produced by Sukehan Bioengineering Co., Ltd. Enzyme components include cellulase, xylanase, laccase, protease, high-temperature amylase, lignin degrading enzyme and pectinase. Both xylanase and protease are alkaline enzyme preparations with a pH value of about 7.5 ~11, the weight ratio of each component is white rot fungus 10%~15%; fermentation bacteria 10%~15%; cellulase 8%~12%; xylanase 10%~15%; laccase 8% %~12%; protease 10%~15%; high temperature amylase 10%~15%; lignin degrading enzyme 8%~12%; pectinase 10%~15%.

[0016] The specific steps of the above-mentioned grass fiber bioseparation composite preparation are as follows: mix the fungus component and the enzyme component according to the usage ratio, and then put them i...

Abstract

The invention discloses a grass fiber bio-separation compound preparation and an application method thereof. The grass fiber bio-separation compound preparation comprises bacteria components and enzyme components, wherein the bacteria components comprise white rot fungi and zymogeneous bacteria, and the enzyme components comprise cellulose, xylanase, laccase, protease, thermostable amylase, ligninase and pectinase. According to the grass fiber bio-separation compound preparation, straw serving as the raw material is treated with a biological method, a biological cycle liquid and a waste cooking liquid produced in the treatment process can be recycled without drainage, and lignin can be extracted; and besides, according to the method, straw does not require cutting and dust removal, and the cooking does not require high temperature and high pressure, so that a large quantity of manpower and electric charges is omitted, and the preparation and the method are suitable for a plurality of raw materials such as wheat straw, straw, cotton stalks, reeds and the like, can be used for producing a paddle board, molded pulp, various types packaging paper, office paper and household paper and have the advantages of low cost and environment protection.

Description

technical field [0001] The invention relates to the technical field of biopulping, in particular to a grass fiber bioseparation composite preparation and a use method thereof. Background technique [0002] my country is a large agricultural country with extremely rich biomass resources. The annual output of crop straw alone reaches 700 million tons per year, of which nearly 200 million tons of rice straw accounts for about 30% of the straw resources. Most of these straws are discarded in the fields, or directly burned as living energy, resulting in waste of resources and environmental pollution. Crop stalks can be used to produce pulp, and various biological enzymes are used to treat cellulose, lignin, and hemicellulose in the stalk at an appropriate temperature, retain and soften cellulose, and quickly convert hemicellulose, pectin, and sugars It is other soluble and volatile substances (it has no effect on papermaking and pulping), because biological enzymes have a soften...
