A fungus belonging to the genus Carbonara and its application in the preparation of fungi-grained wood

Abstract

The invention discloses Daldinia childiae L2Ma and application thereof in preparation of bacterium grain wood, belonging to the technical field of microorganisms. The strain is collected in China General Microbiological Culture Collection Center; the address is No.3, Yard 1, Beichen West Road, Chaoyang District, Beijing City; and the collection number is CGMCC No:5954. The strain has excellent impregnation capability for a wood-based material, the impregnation time is short, and the impregnation depth is large; beautiful colors and grains can be formed on the surface of the material; and the physical mechanical strength is not influenced. A method for preparing a bacterium grain wood by using the strain comprises the steps of strain activation, expanding propagation and inoculation culture; and the method comprises the following specific steps: inoculating the strain on an activation and expanding propagation culture medium, performing activation and expanding propagation at 22-30 DEG C for 7-15 days, sterilizing the wood-based material, enabling the wood-based material to be sufficiently in contact with the strain subjected to activation and expanding propagation, and culturing at 22-30 DEG C for 6-8 weeks. According to the invention, the method is reasonable in process and simple to operate; and the prepared bacterium grain wood has favorable decoration effect and has no influence on the physical mechanical property of the base material, thereby being beneficial to large-scale production and popularization.

Description

technical field

[0001] The invention belongs to the technical field of microbes, and in particular relates to a fungus strain of the genus Anthroporum which has a short infection time and large depth, beautiful color and texture, and has no influence on the physical and mechanical strength of wood-based materials and its use in the preparation of fungus-grained wood. Applications. 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. ...
