Efficient submerged fermentation Agrocybe aegerita medium and preparation method therefor

Abstract

The invention discloses an efficient submerged fermentation Agrocybe aegerita medium. The medium comprises the following components in parts by weight: talcum powder, broadleaf tree chip, litchi seed, retinervus citri reticulatae, river snail powder, shrimp powder, tomato vine, small bamboo branches, copper glycinate, zinc glycinate, yeast powder, peptone, limestone, light calcium carbonate, fermental animal dropping, fine sand, marigold leaf, corncob granule, high-protein rice bran, laetiporus sulphureus, alginate, sulfate magnesium, oyster shell powder, silk and an appropriate amount of water. The submerged fermentation Agrocybe aegerita efficient medium adopts the broadleaf tree chip, litchi seed, retinervus citri reticulatae, tomato vine, small bamboo branch, marigold leaf and corncob granule through acid treatment and alkali treatment, the Agrocybe aegerita medium is prepared through submerged fermentation of oyster shell loaded saccharomycetes, so that bacteria and diseases are inhibited, and rich nutrients are provided for the Agrocybe aegerita; and efficient cultivation of Agrocybe aegerita can be realized. According to the medium, the raw material cost is low, the preparation method is simple, the cultivation effect is high, and the medium is worth for generalization.

Description

technical field [0001] The invention relates to the field of edible fungus culture medium, in particular to a high-efficiency culture medium for submerged fermented tea tree mushroom and a preparation method thereof. Background technique [0002] Tea Tree Mushroom is a kind of wood-rot fungus, which has the effects of clearing heat, calming the liver, improving eyesight, diuresis, and invigorating the spleen. It is a green food that combines high protein, low fat, nutrition, health care, and physical therapy. However, because tea tree mushroom has no laccase activity inside, its ability to utilize lignin is relatively weak, and the raw materials used in traditional cultivation often result in low yield and quality. Submerged fermentation culture can obtain a large amount of mycelia and metabolites in a short period of time, and its production efficiency is unmatched by traditional cultivation methods. It is of great significance to carry out research on submerged fermentatio...

Problems solved by technology

At present, there are many reports on the use of oyster shells as a natural porous adsorption in the field of slowing down fertilizers to maintain fertilizer and improve fertilizer utilization, but there are few reports on the use of oyster shells in submerged fermentation regulation of culture media

[0004] Bombyx mori silk is a natural protein fiber, mainly composed of sericin in the outer layer and silk fibroin in the inner layer. It has good biocompatibility, can promote the proliferation and differentiation of cells, induce the regeneration of tissue cells, and has no antigenic effect. It is biodegradable, and the structure contains periodic hydrophilic and hydrophobic regions, which make it have a strong interaction with the protein and can maintain the activity of the protein. There is no report on the use of silkworm silk for the regulation of submerged fermentation in the medium.
