Bamboo parasitic fungus and application thereof in fermentation production of hypocrellin

Abstract

The invention discloses a bamboo parasitic fungus and application thereof in fermentation production of hypocrellin. Three bamboo parasitic fungi are separated from Shiraia bambusicola respectively collected from Huangshan region of Anhui province, Quzhou region of Zhejiang province and Yinbin region of Sichuan province, are cultured by virtue of a basal culture medium and is processed by virtue of ion beams, and therefore, a strain with the highest vigorous activity is obtained, is named as Shiraia bambusicola NJTECH-1 and has been preserved in China General Microbiological Culture Collection Center with a preservation number of CGMCC NO. 11617. The bamboo parasitic fungus has very high metabolic activity and is applied to the fermentation production of the hypocrellin, and the yield of the hypocrellin is high. The field waste straws and animal dung can be taken as fermentation substrates, so that the quantity of incinerated straws can be reduced, and the environmental pollution can be reduced while the cost is saved.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation, and in particular relates to a bamboo yellow fungus and its application in fermenting and producing hypocrellin. Background technique [0002] Bamboo yellow is mainly distributed in some provinces in the southeast of China. In addition, it is also distributed in Japan in Asia, but it has not been reported in other countries. Hypocretin produced by bamboo yellow fungus has good effects of dispersing stasis and promoting blood circulation, dispelling wind and dampness, invigorating vital energy, promoting metabolism, and enhancing physical fitness. It is mostly used clinically to treat gastric pain, rheumatoid arthritis, Traumatic injuries and sciatica and other diseases. Moreover, this pigment is safe and non-toxic, bright red in color, strong in coloring power and rich in health care functions, and has broad prospects as a food pigment.

Problems solved by technology

[0003] The traditional production method of hypocrellin is generally divided into biosynthesis method and chemical synthesis method. The biosynthesis method mainly uses corn flour, bran, wheat and other food crops as raw materials, and uses bamboo yellow fungus to ferment hypocrellin. After separation and purification, although the output has increased compared with other production methods, in the era of rising food prices, this method also makes the cost of the final product much higher, which is not conducive to the large-scale application of hypocrellin

The other is a chemical synthesis method, using 3,5-dihydroxybenzoic acid as the initial reactant, and through 12 steps of chemical reactions, hypocrellin is synthesized. However, this method has many and complicated reaction steps and many side reactions. The reagent is highly toxic and costly, so it is not a good way to produce hypocrellin

[0004] In 2005, China's corn stalks reached about 20207×10 4 t, and the proportion of straw returning to the field is very low. Although the country explicitly prohibits the burning of straw, it still cannot completely solve the problem of excessive straw.
