Phomopsis sp. fungus strain and application to fungus-line wood preparation thereof

Abstract

The invention discloses a phomopsis sp. fungus strain of J9GAN and an application to fungus-line wood preparation thereof, and belongs to the field of microbial technology. The strain is preserved at China general microbiological culture collection center at No. 3, Courtyard 1, Beichen West Road, Chaoyang district, Beijing, and has a preservation number of CGMCC No: 7108. The strain has excellent dip dyeing capability for wood substrates; the dip dyeing time is short and the dip dyeing depth is great; beautiful color and texture can be formed on substrate surfaces; and the physical mechanical strength is not influenced. The method for preparing fungus-line wood by using the strain comprises the steps of strain activation, amplification and propagation, and inoculation and culture. Firstly, the strain is inoculated on an activation, amplification and propagation culture medium; activation, amplification and propagation are carried out at 22-30 DEG C for 7-15 days; then a wood substrate is disinfected, and fully contacted with the amplified and propagated strains; and culture is carried out at 22-30 DEG C for 4-8 weeks. The method of the invention is reasonable in process, and easy to operate; the prepared fungus-line wood has very good decorative effect, has no influence on physical mechanical properties of the substrate, and is suitable for large-scale production, popularization and application.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a Phomopsis 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 use in the preparation of fungus-grained wood. application. 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, th...

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 the dead wood in a small part of the forest; 2. The 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, etc. or other microorganisms Interference, etc.; 3. Natural fungal grain wood is formed under natural conditions, and there is often the problem of excessive infection of certain fungus species 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 medicaments will be inhaled during post-treatment such as anti-corrosion and flame-retardant, which will double the cost; 4. Natural fungal 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. The 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
