Description

technical field

[0001] The invention relates to a Luo Han Guo endophytic bacteria strain producing extracellular polysaccharides, a method for producing extracellular polysaccharides and an application of the extracellular polysaccharides, and belongs to the technical field of microorganisms. Background technique

[0002] Luo Han Guo [Siraitia grosvenorii (Swingle) C. Jeffrey] is the fruit of the perennial rhizome vine Luo Han Guo of Cucurbitaceae Luo Han Guo. It is a unique plant in my country and grows in Guangxi, Guangdong, Jiangxi, Hunan and Guizhou. Yongfu County is the birthplace and main producing area of ​​Luo Han Guo. Luo Han Guo fruit is rich in a variety of essential amino acids, trace elements, and multivitamins. In addition, it contains active ingredients such as flavonoids, polysaccharides, sweet glycosides, and polyphenols. Modern pharmacological research has confirmed that Luo Han Guo has a variety of pharmacological effects such as antitussive and asthma, la...
