Multienzyme complex preparation and preparation method and application thereof

Abstract

The invention provides a multienzyme complex preparation and a preparation method and application thereof. The multienzyme complex preparation is characterized by being prepared by adding water to multienzyme complex, wherein the weight ratio of the multienzyme complex to the water is 1:(50-100); and the multienzyme complex comprises the following components in parts by weight: 30-35 parts of laccase, 25-35 parts of xylanase, 10-20 parts of pectinase, 0.1-10 parts of amylase, 0.3-10 parts of lipase, 0.1-5 parts of tannase, 0.1-3 parts of coenzyme, 0.1-3 parts of stabilizing agent and 0.3-25 parts of diatomite. The multienzyme complex preparation can be applied to the preparation process of the fiber pulp for papermaking, the fiber pulp in accordance with the papermaking production requirement can be obtained without further adopting the high-temperature / pressure chemical cooking method in the pulping process, and the original lignin can be preserved to the greatest extent in the fiber pulp preparing process.

Description

technical field [0001] The invention relates to a biological preparation and its preparation method and application, in particular to a multi-enzyme compound preparation and its preparation method and application. Background technique [0002] In recent years, more and more biological agents have been widely used in the field of industrial production, which greatly reduces the pollution to the environment while replacing chemical agents. For example, in the field of paper industry production, the chemical pulping method is pretreated with enzyme Instead of the pure chemical pulping method, the use of chemicals in the pure chemical pulping method is greatly reduced, and the discharge of sewage with extremely high BOD and COD loads and highly toxic and carcinogenic substances in the pulping process is greatly reduced. [0003] However, the existing enzyme pretreatment chemical pulping method still needs to use high temperature and high pressure chemical cooking (mainly alkali ...

AI Technical Summary

Problems solved by technology

[0003] However, the existing enzyme pretreatment chemical pulping method still needs to use high temperature and high pressure chemical cooking (mainly alkali cooking) to obtain fiber pulp that meets the requirements of papermaking after first using enzyme preparations to pretreat the material. Among them, lignin is destroyed to the greatest extent in the chemical cooking process, making it difficult to separate lignin from waste liquid for further utilization after pulping, for example: for the production of functional bio-organic fertilizer; and the above enzyme preparation The pulp produced by chemical pulping is used to make packaging boxes or paper products. Because chemicals are used in the pulp preparation process, the prepared packaging boxes or paper products inevitably contain chemical residues, which are safe to use and degraded. The problem of post-pollution of the environment requires further treatment to solve the above problems, which increases the processing cost of paper products such as packaging boxes and makes the production process more complicated, which is not conducive to large-scale production and processing
