Embodiment 1

[0018] A liquid culture medium for increasing the content of trace elements in Agaricus blazei, which contains the following raw materials:

[0019] 1000ml, glucose 1.5g, sucrose 2.5g, white sugar 3g, soluble starch 1g, beef extract 4g, peptone 3.5g, soybean powder 0.3g, potassium dihydrogen phosphate 1g, ammonium nitrate 0.06g, magnesium sulfate 1.5g, calcium sulfate 0.15g , 0.005 g of sodium molybdate, 0.01 g of sodium selenite, and 0.0005 g of lanthanum nitrate.

Embodiment 2

[0021] A liquid culture medium for increasing the content of trace elements in Agaricus blazei, which contains the following raw materials:

[0022] Water 1000ml, glucose 3g, sucrose 3g, white sugar 2g, soluble starch 1g, beef extract 3.5g, peptone 3.25g, soybean powder 0.35g, potassium dihydrogen phosphate 2g, ammonium nitrate 0.06g, magnesium sulfate 1.05g, calcium sulfate 0.1g , Sodium molybdate 0.0055g, Sodium selenite 0.009g, Rare earth element 0.0009g.

[0023] Utilize the culture medium prepared in Examples 1 and 2 to inoculate Agaricus blazei, and cultivate it at 24-28° C., the average growth rate of mycelium in Example 1 is increased by 12.9%, and the mycelium is strong; the polysaccharide yield reaches 10.82%, phosphorus, potassium, The contents of magnesium, calcium, selenium and molybdenum elements are significantly increased; the average growth rate of mycelia in Example 2 is increased by 11.2%, the mycelium is strong, the yield of polysaccharides reaches 9.63%, a...

Abstract

The invention provides a liquid medium for improving agaricus blazei murill microelement content. The liquid medium comprises, by weight, 1000ml of water, 1-3g of glucose, 2-4g of sucrose, 2-4g of white sugar, 0.5-1g of soluble starch, 3-5g of beef extracts, 3-4g of peptone, 0.1-0.5g of bean flour, 1-3g of potassium dihydrogen phosphate, 0.05-0.1g of ammonium nitrate, 1-2g of magnesium sulfate, 0.05-0.3g of calcium sulfate, 0.005-0.006g of sodium molybdate, 0.008-0.01g of sodium selenite and 0.0005-0.001g of rare earth element. Compared with the prior art, according to the liquid medium, adding quantity of a carbon source and a nitrogen source is controlled, polysaccharide content of products is improved, absorption of agaricus blazei murill for phosphorus, potassium, magnesium, calcium, selenium and molybdenum is facilitated, absorption of the agaricus blazei murill for heavy metal elements is reduced, and edible and health care values of the products are improved.

Description

technical field [0001] The invention belongs to the field of mushroom cultivation, and specifically relates to a liquid culture medium for increasing the content of trace elements in Agaricus blazei, which contains elements such as selenium, calcium, iron, magnesium, potassium, molybdenum, etc., promotes the growth of Agaricus blazei and enriches trace elements, and improves 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 variet...
