Abstract

The invention discloses a method for improving the yield and product activity of a liquid fermentation product of Paecilomyces cicadae, which comprises the following steps: (1) extracting traditional Chinese medicinal materials composed of 10-40 parts by weight of coix seed, 10-40 parts by weight of radix astragali, 10-40 parts by weight of Chinese wolfberry and 10-40 parts by weight of rhizoma atractylodis macrocephalae through a water solution, thus obtaining a traditional Chinese medicine compound water extract liquid; (2) adding the traditional Chinese medicine compound water extract liquid prepared in the step (1), rhizoma atractylodis macrocephalae lactone and Tween-80 into a fermentation basal culture medium, thus obtaining a Paecilomyces cicadae fermentation culture medium; and (3) inoculating a Paecilomyces cicadae strain into the Paecilomyces cicadae fermentation culture medium prepared in the step (2), performing liquid fermentation to obtain a fermentation liquid, and separating to obtain a fermentation product. According to the invention, particular kinds of traditional Chinese medicine compound water extract liquid, rhizoma atractylodis macrocephalae lactone and Tween-80 are added, so that the biomass and polysaccharide yield of the Paecilomyces cicadae can be obviously improved, and meanwhile, the activity of the polysaccharide is also improved obviously.

Description

technical field [0001] The invention belongs to the field of fermentation engineering, and in particular relates to a method for increasing the yield and activity of Paecilomyces cicadae liquid fermentation products. Background technique [0002] Paecilomyces cicadae (Mique1) Samson, also known as the female cicadae, belongs to the genus Cordyceps along with Cordyceps sinensis and Cordyceps militaris. strain. The active ingredients and efficacy of Paecilomyces cicadae are similar to those of Cordyceps sinensis, containing nucleosides, myriocin, ergosterol, cordycepic acid, polysaccharides, various essential amino acids, mannitol and alkaloids and other secondary metabolites ( He Liang, Ma Suyun, Cheng Junwen, et al. Research progress on bioactive substances of the medicinal fungus Paecilomyces cicadae [J]. Journal of Food and Biotechnology, 2012,31(1):8-15.). Modern pharmacological studies have shown that Paecilomyces cicadae has many health care functions, such as immune ...
