Problems solved by technology
Firstly, the discarded fungus packs may come into contact with miscellaneous bacteria after fruiting and during handling; secondly, the edible fungus packs may also be polluted by Penicillium and Trichoderma during the pulverization and stirring process; In a warm and humid environment, it is easier to breed bacteria
If a test piece is infected with bacteria, other test pieces will also increase the probability of contamination, resulting in a large amount of test loss

Embodiment Construction
[0033] For better understanding and implementation, the present invention will be described in detail below in conjunction with the accompanying drawings.
[0034] Such as figure 1 , 2 , 3, 4, 5, and 6, a method for aseptic molding of a bacterium-containing composite material fermented by catkins comprises the following steps:
[0035] 1. Prepare the mycelium liquid: transfer the ganoderma lucidum strain to the PDA culture medium to grow for 7-21 days, then let it stand for 3 days, and then put it in a shaker for 3-6 days at a constant temperature in an air bath under the conditions of 26°C, 100r / min, until a large number of suspended mycelium balls appear, the mycelial liquid is obtained and placed for later use;
[0036] 2. Prepare the admixture: soak the catkins, sawdust and peanut stalks in a mass ratio of 2:1:1 to ensure that the water content is about 60%. The fermentation time is 1-2 days, and the color is uniform after fermentation. Brown, odorless, fragrant, the ma...

The invention discloses a sterile forming method of a bacteria-containing composite material fermented by catkin, which is characterized in that catkin, sawdust and waste peanut vine straws after peanut harvesting are mixed with medium sand, the composite material is inoculated with hypha liquid, and the bacteria-containing composite material is prepared by culturing and forming, so that the catkin and agricultural wastes which influence the environment are effectively utilized; the problems of environment and grain resource waste are solved to a certain extent; the material can be naturally degraded and recycled, so that resources are saved; pollution of infectious microbes in the air is fundamentally solved, and the survival rate of hyphae is increased; the method is simple, fast, easy to operate and high in hypha survival rate, and composite material test success probability is increased.
Description
technical field [0001] The invention relates to the technical field of material synthesis, in particular to an aseptic molding method of a bacteria-containing composite material fermented from catkins. Background technique [0002] Mycelium is composed of chitin, cellulose, protein, etc. Mycelium grows and spreads in the composite material, forming a mycelium network structure, which plays a role in cementing the matrix material, and can be regarded as a natural "adhesive". ; The growth environment of the bacteria-containing material can maintain a certain temperature and humidity during the molding process, without consuming other energy sources. It is a non-polluting, recyclable, and easily degradable composite material, which is expected to replace traditional cushioning materials and thermal insulation materials in the future and filling materials. [0003] The main component of catkins is cellulose, which contains 0.89% nitrogenous substances, 1.55% pentosan, 1.14% ash...
