Description
Technical field
The invention belongs to technical field of biological fermentation, be specifically related to a kind of zymotechnique that improves yield of ganoderma lucidum triterpenoid.
Background technology
Glossy ganoderma (Ganoderma lucidum) is the famous medicinal fungi of China.Because it can prevent and treat numerous disease, once be called as " celestial grass " in ancient times.Pharmacopoeia of the People's Republic of China regulation, red sesame (Ganoderma lucidum) and purple sesame (Ganoderma sinense) are the glossy ganoderma certified products.Comprise that in recent years the country in Southeast Asia of China and the U.S. and Canadian many scholars have carried out deep research to glossy ganoderma, modern pharmacology studies have shown that the crucial effective component of glossy ganoderma is ganoderan and Ganoderma triterpenoids.Wherein Ganoderma triterpenoids have anti-inflammatory analgetic, calmness, detoxify, protect the liver, AIDS virus resisting, function such as antitumor, be the important substance basis of glossy ganoderma performance drug effect.
Present stage, the output of glossy ganoderma thalline and crucial effective component thereof becomes the bottleneck that hinders the ganoderma lucidum prod application.Since the wild Ganoderma rareness, and traditional cultivating method cycle is long, and output far can not satisfy market demand.Because producing glossy ganoderma, the liquid submerged fermentation technology has characteristics such as with short production cycle, product active substance and wild Ganoderma basically identical, the present most effectual way of obtaining glossy ganoderma and active substance thereof that become.In recent years, the liquid fermentation technology of glossy ganoderma has been obtained remarkable progress, but the output that how further to improve glossy ganoderma thalline or crucial effective component has become and accelerated ganoderma lucidum prod industrialization process problem demanding prompt solution to reduce production costs, to increase economic efficiency.
The fermentation technique of crucial effective component-Ganoderma triterpenoids of glossy ganoderma mainly is divided into two big classes, the first kind mainly is by the optimization to glossy ganoderma fermentation matrix and fermenting process, as optimize substratum and form, optimize Fermentation Process of Parameter, or adopt strategy such as feed supplement-batch fermentation to improve the output of Ganoderma triterpenoids, as:
Document: Li Pingzuo, Xu Rou, the summer knot is red, Zhang Kechang. and deep glossy ganoderma fermenting is produced the research of tetracyclic triterpene acid. industrial microorganism, 2000,30 (1): 15-17.Reported the basic technology of a kind of submerged fermentation production tetracyclic triterpene acid, but the output of tetracyclic triterpene acid is lower.
Document: Tang YJ, Zhong JJ.Fed-batch fermentation of Ganoderma lucidumfor hyperproduction of polysaccharide and anoderic acid.Enzyme andMicrobial Technology, 2002,31:20-28.Reported that a kind of employing adds the stream of lactose and add fermentation process, the output that obtains Ganodenic acid (Ganoderma triterpenoids) is 297.9-367.1mg/L.
Chinese patent: clock Kien Giang etc., application number 00111953.2 has proposed the technology that solution fermentation is produced ganoderan and Ganoderma triterpenoids simultaneously.Adopt liquid aerobic fermentation, liquid aerobic fermentation-leave standstill to cultivate or liquid leaves standstill the fermentation process of cultivation, Ganodenic acid (Ganoderma triterpenoids) content in the glossy ganoderma thalline of its production can reach 2.8mg/100mg.The fermentation strategy of this technology is better, output also can improve, but that shortcoming is the fermentation period of Ganoderma triterpenoids is oversize, and the liquid aerobic fermentation adds that the total fermentation time that leaves standstill cultivation has surpassed 20 days, and the fermentation time of general ganoderma lucidum prod is 4-8 days, so its integral production efficient is lower.
Another kind of is on the basis of fermentation technology optimization, promotes the biosynthesizing of Ganoderma triterpenoids by the interpolation allogenic material, thereby improves the output of Ganoderma triterpenoids.As:
Document: Wang Yuhong, fourth Double Ninth Festival, Zhang Kechang, Xu Rou. bitter buckwheat is produced the influence of Ganodenic acid to glossy ganoderma fermentation. food and fermentation industries, 2003,29 (9): 97-99.After having reported the bitter buckwheat of interpolation Chinese medicine, the output of Ganodenic acid (Ganoderma triterpenoids) increases, and the production peak of Ganodenic acid is 310mg/L in its fermented liquid.Document: Liu Gaoqiang, fourth Double Ninth Festival, Zhang Kechang. dung beetle is to the influence of fermented hyphostroma of Ganoderma growth and the formation of triterpene product. the fungus journal, 2008,27 (5). after having reported interpolation insect dung beetle, the output of Ganoderma triterpenoids increases, and the production peak of triterpene in its fermented liquid (the outer triterpene of born of the same parents) is 304.3mg/L.Though above method can make yield of ganoderma lucidum triterpenoid increase, the cost of Chinese medicine is higher, and has the hidden danger of toxic side effect aspect.
We are by a large amount of screening experiments, found a kind of external source substance that can significantly improve yield of ganoderma lucidum triterpenoid, simultaneously ferment strategy and liquid nutrient medium have been carried out optimization design, formed and a kind ofly can significantly improve yield of ganoderma lucidum triterpenoid and the simple Ganoderma triterpenoids production technique of production technique in the Ganoderma fermentation liquid.
