[0018] A kind of Agaricus blazei liquid culture medium, contains following raw material:

[0019] Water 1000ml, glucose 0.7g, sucrose 2.5g, sugar 4g, corn flour 0.5g, beef extract 4g, peptone 3g, soybean powder 0.3g, potassium dihydrogen phosphate 1g, ammonium nitrate 0.06g, magnesium sulfate 1.2g, calcium chloride 0.1g, sodium selenite 0.07g, lanthanum nitrate 0.0006g.

Embodiment 2

[0021] A kind of Agaricus blazei liquid culture medium, contains following raw material:

[0022] Water 1000ml, glucose 0.78g, sucrose 3g, white sugar 3g, corn flour 2g, beef extract 3g, peptone 3g, soybean powder 0.45g, potassium dihydrogen phosphate 1.25g, ammonium nitrate 0.06g, magnesium sulfate 1.5g, calcium chloride 0.15 g, sodium selenite 0.07g, praseodymium nitrate 0.0006g.

[0023] Utilize the substratum prepared in Examples 1 and 2 to inoculate Agaricus blazei, cultivate at 24-28° C., the average growth rate of mycelia in Example 1 increases by 13.4%, and the mycelium is strong; the polysaccharide yield reaches 11.1%, which is significantly improved; implementation In Example 2, the average growth rate of mycelia increased by 10.5%, the mycelium was strong, and the polysaccharide yield reached 9.8%, which was significantly improved.

Abstract

The invention provides an agaricus blazei murill liquid culture medium which comprises 1000ml of water, 0.5-1g of glucose, 2-4g of sucrose, 3-4g of white granulated sugar, 0.5-2g of corn flour, 3-5g of beef extract, 3-4g of peptone, 0.1-0.5g of bean flour, 1-3g of monopotassium phosphate, 0.05-0.1g of ammonium nitrate, 1-2g of magnesium sulfate, 0.1-0.2g of calcium chloride, 0.06-0.09g of sodium selenite and 0.0005-0.001g of rare earth elements. Compared with the prior art, the agaricus blazei murill liquid culture medium has the advantages that growth of agaricus blazei murill is promoted by controlling the adding quantity of carbon sources and nitrogen sources, mushroom bodies are thick and strong, the sodium selenite and the rare earth elements are added, rapid growth of the agaricus blazei murill can be promoted, and the polysaccharide content and edible and health care values of products are increased.

Description

technical field [0001] The invention belongs to the field of mushroom cultivation, and in particular relates to a Agaricus blazei liquid culture medium, which contains selenium and rare earth elements to promote the growth of Agaricus blazei and increase the polysaccharide content. Background technique [0002] Agaricus Blazei (also known as Brazil mushroom), native to Brazil and Peru. It is a saprophytic fungus that grows in summer and autumn. It lives in a high-temperature, humid, and ventilated environment. It has an almond fragrance and a crisp and tender taste. The cap of Agaricus blazei is tender, the stipe is crisp, the taste is excellent, and the taste is 5-7 grams. [0003] The protein composition of Agaricus blazei includes 18 kinds of amino acids, the 8 kinds of essential amino acids for the human body are complete, and it also contains a variety of vitamins and ergosterol. The mannan contained in it is effective in inhibiting tumors (especially ascites cancer),...
