Abstract

The invention discloses a synthetic medium of broad-leave Sparassis crispa. The synthetic medium comprises carbon, nitrogen, potassium phosphate monobasic, other component and water. The other component is at least one of magnesium sulfate and vitamin B1. The final concentration of the carbon, the nitrogen, the potassium phosphate monobasic, the magnesium and the vitamin B1 in the synthetic medium is sequentially 8.0-25.0g / L, 0.15-4.5g / L, 0.5-2.0g / L, 0-1.0g / L and 0-0.1g / L. The carbon comes from sucrose or glucose or maltose or lactose or soluble starch. The nitrogen comes from ammonium citrate or ammonium nitrate or ammonium phosphate or potassium nitrate or ammonium sulfate. The medium has the advantages of clear component, stability in quality, few impurities and the like, is suitable for industrial fermentation production and physiological research of Sparassis crispa and is favorable for separation and extraction of downstream metabolite.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a synthetic culture medium for Hydrangea broadleaf. Background technique [0002] Hydrangea broadleaf [Sparassis latifolia Y.C.Dai&Zheng Wang] is a rare edible and medicinal fungus, belonging to Kingdom Fungi (Kingdom Fungi), Basidiomycota (Basidiomycota), Polyporales (Polyporales), Hydrangeaceae in biological classification (Sparassidaceae), Hydrangea (Sparassis). Recent studies have shown that Hydrangea broadleaf is widely distributed in subtropical and temperate regions of East Asia, including Jilin, Heilongjiang, Yunnan, Japan and other places in China (Zhao et al., 2012, Mycological Progress, DOI 10.1007 / s11557-012-0853-7) , born in late summer and early autumn on the ground of spruce, fir or pine forests and mixed forests. [0003] Hydrangea is rich in protein, essential amino acids and vitamins and other nutrients (Chandrasekaran et al., 2011, International Journal of Medici...
