Xylaria venosula fungi and application of the same in preparation of fungi pattern wood

Abstract

The present invention discloses a strain of Xylaria venosula J22QIU and an application of the Xylaria venosula J22QIU in preparation of fungi pattern wood, and belongs to the technical field of microorganisms. According to the present invention, the strain is preserved in the China General Microbiological Culture Collection Center, the address is Institute of Microbiology, Chinese Academy of Sciences, 3# Court No.1, Beichen West Road, Chaoyang District, Beijing, and the preservation number is CGMCC No:5964; the strain provides excellent dip dyeing ability for the wood base material, the dip dyeing time is short, the dip dyeing depth is high, beautiful color and texture can be formed on the material surface, and the physical and mechanical strength is not affected; the method for preparing the fungi pattern wood by using the strain comprises strain activation and propagation, and fungi inoculation culture, wherein the strain is inoculated on an activation and propagation culture medium, activation and propagation is performed for 10-15 days at a temperature of 22-30 DEG C, the wood base material is sterilized and completely contact the obtained strain, and culture is performed for 4-8 weeks at a temperature of 22-30 DEG C; and the method has characteristics of reasonable process and simple operation, the prepared fungi pattern wood has a good decorative effect, the physical and mechanical property of the substrate is not affected, and the method is suitable for large-scale production and promotion application.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a carbon horn fungus strain with short infection time and large depth, beautiful color and texture, and no influence on the physical and mechanical strength of wood-based materials and its application in the preparation of fungi-patterned wood. Background technique [0002] The fungal discoloration of wood has long been regarded as a defect of wood, which reduces the value of wood. In fact, fungal discoloration, such as lines and stains, has natural and unique characteristics. When the decay is not serious A wonderful touch. If this kind of wood with natural lines or colors is used to make handicrafts, such as vases, earrings, pens, wood veneers, etc., the added value of wood can be increased. The fungus wood with natural patterns and colors will be popular in the market, especially in the decoration, decoration and handicraft markets. [0003] However, the n...

AI Technical Summary

Problems solved by technology

[0003] However, the naturally obtained fungal wood still has the following deficiencies: 1. The raw materials are not easy to obtain, and there is a strong chance, because the natural fungal wood can only be formed in nature when there are bacteria that can form the fungal wood. , so only a small amount of fungal wood can be found in dead branches and fallen trees in a small number of forests; 2. Natural fungal wood takes a long time to form and is affected by many climate and environmental factors, such as dryness, cold, lack of oxygen, strong sunlight, Other microbial interference, etc.; 3. Natural fungal wood is formed under natural conditions, and there is often the problem of excessive infection of certain bacteria on wood-based materials, resulting in serious loss of strength of the material, which cannot be processed and used, or the permeability is significantly increased. , Excessive inhalation of chemicals will be inhaled during post-treatment such as anti-corrosion and flame-retardant, which will double the cost; 4. Natural fungal grain wood is formed under natural conditions, and the size and shape of the wood are unpredictable, and the beautiful lines may be lost during processing 5. Natural fungus wood is formed under natural conditions and is susceptible to insect pests or other fungal infections, making the wood incomplete or forming unsightly decay or discoloration
