Problems solved by technology

Literature survey finds that the research of hydrangea cultivation is mostly solid culture, although there are a few reports of liquid fermentation, You Xiong et al. 41-45) and Liu Chengrong (Research on liquid fermentation conditions of Hydrangea mutant strains, Jiangxi Agricultural University Journal 2008 (5): 898-902) both used mutant strains of Hydrangea to study, and mutant strains are used in health food and medicine. its limitations, and the strain itself is unstable

Abstract

The invention discloses a special medium for the liquid fermentation of a rare edible-medicinal fungus Sparassis crispa and a culture method thereof. 1ml of the medium contains 20.0-200.0g of a composite carbon source, 0-60.0g of sugar, 0-5.0g of peptone, 0-5.0g of KH2PO4, 0-2.5g of MgSO4, 0-10.0ml of a pine needle juice, 0-3.0g of plant oil, and the balance water, and the pH value of the medium is adjusted to 2.0-6.0. The culture method comprises the following steps: 1, inoculating strains of Sparassis crispa to the special medium for the liquid fermentation of Sparassis crispa according to an inoculation amount of 5-20%, wherein the initial pH value of the medium is 2.0-6.0; and 2, carrying out oscillation culture under natural illumination conditions, wherein the temperature is 20-30DEG C, and the rotation speed is 100-200rpm. The method of the invention breaks through present limitations of solid culture and artificial cultivation of Sparassis crispa; and the fermentation production of the Sparassis crispa, which is carried out by using the medium and the culture method of the present invention, has the advantages of fast growth speed, short period, high yield, simple process,low cost and the like, can be adapted to the industrialized fermentation production of Sparassis crispa.

Description

technical field [0001] The invention relates to a liquid fermentation culture method of a rare edible and medicinal fungus hydrangea and a special culture medium thereof. Background technique [0002] Hydrangea [Sparassis crispa (Wulf.) Fr] is a rare edible and medicinal fungus, belonging to Kingdom Fungi (Kingdom Fungi), Basidiomycota (Basidiomycota), Polyporales (Polyporales), Hydrangeaceae in biological classification (Sparassidaceae), Hydrangea (Sparassis). Hydrangea is distributed in Jilin, Heilongjiang, Yunnan and other places in my country, and also in Japan, Europe, and North America. It is born in spruce, fir or pine forests and mixed forests in late summer and early autumn. [0003] The main active ingredient of hydrangea is rich in β-glucan, which is 43.6% as determined by the Japan Food Analysis Laboratory, which is more than twice that of Ganoderma lucidum and Agaricus blazei, the most among mushrooms, and has high medicinal and health benefits. It has the tit...
