Abstract

The invention provides a liquid fermentation medium for edible fungi and a preparation method thereof and particularly relates to the technical field of biological engineering. The liquid fermentationmedium for edible fungi is prepared mainly by mixing bran extract, potato extract, brown sugar, glucose, mulberry extract, Azolla imbricata and Shiyacha Tea (from Adinandra nitida); when water is added to prepare a liquid medium, good solubility is provided, and nutrients can be well dissolved in water; a mother strain inoculated in the liquid medium can directly absorb nutrition from the liquidmedium, growth and development and nutrient accumulation are benefited for hypha of the mother strain; material basis is provided for the enrichment of nutrients after formation of fruiting bodies. The liquid fermentation medium prepared herein is capable of effectively promoting the growth of hypha and increasing dry weight and diameter of the hypha; the content of nutrients in the harvested fruiting bodies can be increased, and nutritional value of the fruiting bodies is improved. The preparation method herein has good stability and reliability, the parameters are easy to control, and the preparation method is suitable for large-scale production.

Description

【Technical field】 [0001] The invention relates to the technical field of bioengineering, in particular to an edible fungus liquid fermentation medium and a preparation method thereof. 【Background technique】 [0002] Liquid fermentation technology is one of the modern biotechnology, it refers to imitating nature in the biochemical reactor, some trace amounts of carbohydrates, organic and inorganic nitrogen-containing compounds, inorganic salts, etc. Elements and other nutrients are dissolved in water as a culture medium. After sterilization, they are inserted into the parent species, and sterile air is introduced and stirred to provide the oxygen required for the respiration and metabolism of edible fungi. The process of mass culture and reproduction of silk. The strains bred by liquid fermentation technology are called liquid strains, which have significant advantages over solid culture. The raw materials for the preparation of the medium are widely sourced, the price is lo...
