Embodiment Construction

[0037] Its steps of the method for cultivating ground fungus are as follows:

[0038] 1. Culture medium preparation: each liter contains 20-60mg of dipotassium hydrogen phosphate, 40-80mg of magnesium sulfate, 20-40mg of calcium chloride, 4-8mg of citric acid, 5-9mg of ferric ammonium citrate, and ethylenediaminetetraacetic acid Sodium salt 1-2mg, sodium carbonate 5-30mg, trace elements 0.5-3ml, the rest is water; sodium nitrate 200-1500mg / L can also be added to the above culture medium.

[0039] Among them, trace elements are contained per 1000 ml: boric acid 1.5-3g, manganese chloride 1-2g, zinc sulfate 0.1-0.25g, sodium nickelate 0.2-0.4g, copper sulfate 0.02-0.1g, cobalt nitrate 0.03-0.05g, The rest is water.

[0040] The prepared culture solution should preferably be sterilized at a high temperature of 118-122°C for 20 minutes, and then used after cooling, or can be sterilized by filtration.

[0041] 2. Preparation of algae species: Wash the fungus with 70%-95% ethanol ...

Abstract

The nostoc commune culture method includes the following steps: soaking nostoc commune in ethyl alcohol solution, washing in sterilized culture liquor, placing the above-mentioned material into a homogenizer, grinding to obtain a paste-like material, then inoculating it into culture liquor, its temp. is controlled at 10-40 deg.C, and the light intensity is controlled at 10-1800 micro E.m(-2).s(-1), changing culture liquor once every 10-20 days until the spherical body of noctoc commune is grown to the required diameter. Said invention is convenient for operation, and its yield is high.

Description

Technical field: [0001] The present invention relates to biotechnology, and more particularly to the cultivation of microalgal organisms. Background technique: [0002] Nostoc is a kind of algae group with wide distribution, complex ecological environment and various morphological structures in the cyanophyta Cyanophyta Cyanophyceae Cyanophyceae segmental algae order Hormogonales Nostocaceae. , leaf-like, filamentous, bubble-like and other shapes, hollow or solid, floating or growing. The protophyte consists of many fine algal filaments with a diameter of a few microns assembled into a group, and the shape of the group varies depending on the "species", such as Nostoc flageliforme Kuetz, Nostoc commune, Nostoc sphaeroides In the fresh state, they are hair-like, flat ear-shaped or small ball (bead)-shaped, and they shrink to varying degrees after drying, all of which have rich nutritional value. It has been recorded in medical books such as "Shaanxi Chinese Herbal Medicine"...
