Method for producing cordyceps militaris sporocarp and fish feed additive at same time

Abstract

The invention discloses a method for producing cordyceps militaris sporocarp and a fish feed additive at the same time. A culture medium formula for producing the cordyceps militaris sporocarp comprises liquid A and solid B; the liquid A is prepared from the following components of 1000ml of water, 10.0 to 15.0g of saccharose, 0.3 to 0.5g of KH2PO4, 0.3 to 0.5g of MgSO4, four tablets of complex vitamin B and 1 tablet of vitamin C; the solid B is prepared from the following materials of 50% of wheat berry, 15% of rapeseed meal, 24% of peanut meal, 1% of dry silkworm chrysalis meal and 10% of rice bran; a ratio of the liquid A to the solid B powder is (2 to 3) to 1. The method comprises the steps of sealing, sterilizing and cooling the culture medium; then inoculating cordyceps militaris strain, inoculating according to a volume ratio of the strain to the culture medium as 1 to 50 and performing dark culture at first and then performing light culture in cultivation, wherein a strain density is 10 to 20 fungus balls / mL; obtaining the sporocarp and fungi residues. A crude polysaccharide content of the fungi residues reaches 27.43%, the fungi residues are naturally dried or stoved and then smashed to 80-mesh granularity, and digestion and absorption of fish bodies are facilitated; furthermore, the fungi residues have fragrant smell and can serve as the fish feed addition, and an adding amount is 10 to 15%.

Description

technical field [0001] The invention relates to the cultivation technology of Cordyceps militaris and the field of production of fish feed additives, in particular to a formulation of a medium for Cordyceps militaris and the application of the fungus residue after producing the fruiting bodies of Cordyceps militaris in fish feed and feed additives. Background technique [0002] Cordyceps militaris ( Cordyceps militaris ), also known as Cordyceps militaris, belongs to the Ascomycotina, Ergotaceae, and Cordyceps of the fungal kingdom. The fruiting body of Cordyceps militaris has similar medicinal and nourishing effects to Cordyceps sinensis, and the content of cordycepin in Cordyceps militaris is dozens of times higher than that of traditional Cordyceps sinensis. It is a precious medicinal fungus. Cordyceps militaris is rich in protein, amino acid and more than 30 kinds of trace elements needed by the human body. It also contains unique physiologically active components such ...
