Large-scale artificial cultivation of mulberry yellow is successful

A (correspondent Yang Yan reporter Zhang Xingyong) at present, in the greenhouse of the cultivation base of Shaanxi Provincial Institute of Microbiology in Dazhai Township, Yangling demonstration Zone, 5000 mulberry bags have grown golden crescent-shaped fruiting bodies one after another, growing gratifying. This marks the success of large-scale artificial cultivation of mulberry in our country.

Sanghuang, known as "forest gold", is a valuable traditional Chinese medicine. With the increase of market demand in the past 10 years, Sanghuang has been exploited predatory. Due to the particularity and complexity of mulberry yellow physiology and ecology, the destroyed wild mulberry resources are difficult to recover, or even about to be exhausted.

In 2006, Lei Ping, an associate researcher of Shaanxi Provincial Institute of Microbiology, led a team to discover mulberry yellow in the Qinling Mountains, isolated bacteria from it, and carried out a series of studies. Through the unremitting efforts of researchers, the team has made major breakthroughs in strain identification, biological characteristics, submerged fermentation of mycelia, artificial domestication and cultivation, active component analysis, safety toxicology and pharmacology research. In 2013, the team broke through the technical bottleneck in the artificial cultivation of mulberry yellow and achieved success.

In addition, the research team also commissioned the Shaanxi Provincial Center for Disease Control and Prevention to carry out acute toxicity tests on artificially cultivated mulberry fruiting bodies and fermented mycelia, and the results showed that they belonged to non-toxic grade. The pharmacological and pharmacological effects of Sang Huang fermentation mycelium were studied systematically with the fourth military Medical University, Northwestern University and the Institute of Medicine of Shaanxi College of traditional Chinese Medicine. the results showed that Sang Huang fermentation mycelium had obvious inhibitory effect on S180 and H22 tumor-bearing mice and HepG2-bearing nude mice tumor, and had certain curative effect on chronic renal failure.
