Abstract

The invention discloses a method of increasing the amino acid content of pleurotus geesteranus, and relates to the technical field of edible fungi cultivation. A pleurotus geesteranus culture medium is composed of sargassum horneri powder, glucose, ammonium sulfate, bamboo vinegar, wheat bran, cotton seed hull, and microbes. Glucose and ammonium sulfate are used together to prominently promote microbes to convert inorganic nitrogen into amino acid nitrogen; the amino acid content of the culture medium is obviously increased; and the contents of 17 amino acids such as glutamic acid, alanine, tyrosine, glycine, and the like, in pleurotus geesteranus, which is cultured in the provided culture medium, are all increased by 8% or more.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a method for increasing the amino acid content in pear mushrooms. Background technique [0002] Pleurotus geesteranus, also known as small oyster mushroom and Ji mushroom, belongs to the phylum Fungi, the class Basidiomycetes, the order Agaricaceae, and the genus Pleurotus in the family Pleurotaceae. The fruiting body is crisp, tender and refreshing, the flesh is thick and tender, with a delicious taste and strong aroma. It is also rich in 17 kinds of amino acids, more than 10 kinds of minerals, and trace elements needed by the human body. In addition, threonine, lysine, and homopic acid are generally lacking in human body. The proteoglycans contained in xiuzhen mushrooms have a strong inhibitory effect on cancer cells and can enhance the immune function of the body. Regular consumption of pear mushrooms can not only improve the metabolism of the human body an...
