Chinese caterpillar fungus taro
Technical field
Adopting Cordyceps sinensis (Ophiocordyceps sinensis) and Cordyceps militaris (Cordyceps militaris), take taro as medium, carries out two bacterium mixed solid fermentation, belongs to technical field of bioengineering.Utilizing bacterial strain Cordyceps militaris preserving number to be CICC 14013, bacterial strain Ophiocordyceps sinensis preserving number is CICC 14088, is produced obtain nutrition and health care taro by two bacterium mixed solid fermentation.
Background technology
Cordyceps (Cordyceps) is under the jurisdiction of mycota (Fungi), Ascomycota (Ascomycota), Ascomycetes (Ascomycetes), excrement shell bacterium subclass (Sordariomycetidae), Hypocreales (Hypocreales), Clavicipitaceae (Clavicipitaceae).Cordyceps sinensis fungus great majority are medicinal fungis, wherein Cordyceps sinensis (Ophiocordyceps sinensis) is generally well known, applicating history is also remote, and the application study of Cordyceps militaris (Cordyceps militaris) is the most deep.
Cordyceps sinensis is recorded in 710 years Christian eras " moon king medicine is examined " the earliest according to textual research, records first appeared in Qing Dynasty Wu Yi Lip river " new compilation of materia medica " (1757 Christian eras) with medicine, thinks its " sweet flat; to protect lung kidney-nourishing; hemostasis and phlegm, phthisical cough, control diaphragm disease all good ".Cordyceps sinensis is China's tradition rare Chinese medicine, and it and ginseng, pilose antler are described as Chinese medicine Triratna together.It has mend and not high, temperature and not fiery, grow and oiliness pharmacodynamic profile, have more negative and positive with the unique effects of mending, make it become nourishing panacea, be described as " kings of hundred medicines " by physician.
Cordyceps militaris is one of Chinese medicinal material of being of great rarity of China, and its medical value is on the books very early, and Li Shizhen (1518-1593 A.D.) (1518) is pointed out in Compendium of Material Medica, and cicada fungus can cure mainly " children's hangs in sky frightened epilepsy, the morbid night crying of babies, palpitaition ".Cordyceps militaris is easy to large-scale artificial and cultivates, and its active component and pharmacological action are similar to Cordyceps sinensis again.
The current grain raw material that Cordyceps sinensis or Cordyceps militaris is applied to ferments by wide coverage.Such as: patent 200610117997.4 adopts Cordyceps militaris industrialization to cultivate discarded object and makes rice flour product, Chinese caterpillar fungus is pulverized rear mixing with the careless highland barley fried and makes health products by patent 200710050135.9, patent 200710166278.6 adopts wheat to cultivate fruiting bodies of cordyceps militaris, patent 200810068734.8 adopts adopting red yeast rice synergistic to ferment thus improves the output of fruiting bodies of cordyceps militaris and cordycepin, patent 200910218363.1 discloses a kind of method being improved primary medicinal component by Poria cocos and Cordyceps militaris solid co-fermentation, patent 201110055425.9 utilizes solid state fermentation to produce Cordyceps militaris fermentation rice, patent 201110348239.4 take lotus seeds as matrix, carries out the solid state fermentation of Cordyceps militaris or winter grass summer grass, patent 201110064459.4 discloses a kind of preparation method of Cordyceps militaris paddy food, patent 201310150267.4 and 201310151228.6 respectively with soya bean and peanut for matrix, carry out solid state fermentation after inoculation Cordyceps militaris, but need in process to add insect enzymolysis liquid, cause cost and difficult quality to control, patent 201210064068.7 discloses a kind of with glossy ganoderma, Phellinus etc. can the mushroom entity of efficient cellulase-producing as medium major ingredient, grain raw material is auxiliary material, inoculate into Cordyceps militaris, Cordyceps sinensis, mushroom, Hericium erinaceus, the bacterial classifications such as acupuncture needle aunt carry out Mixed culture, make health products or additive, but this complex process, edible and medical fungi fruit body is expensive, and after autoclaving, destroy the active ingredient of edible and medical fungi fruit body, complicated component and uncontrollable after other strain fermentation again, the strain combination of various complexity also will cause the instability of end product quality.
In sum, the solid ferment process of current Cordyceps militaris or Cordyceps sinensis all can add mineral salt, insect hydrolyzate or other medicinal ingredient, to improving Chinese caterpillar fungus thalline or cordycepin output and drug effect.Different additives can cause complicated component and import external pollution source, and is not easy to set up quality index system.In addition, the solid ferment process of Cordyceps militaris often using cordycepin (Cordycepin) as important quality index.Cordycepin, is also referred to as 3'-Deoxyadenosine (3-deoxyadenosine), and since self-discovery, its pharmacological action is constantly made known.Personnel study discovery after deliberation, and cordycepin has immunological regulation, antitumor, anti-leucocyte, the multiple pharmacological effect such as antimycotic, antiviral.What is interesting is, cordycepin is mainly stored in Cordyceps militaris, and content in Cordyceps sinensis is atomic, but the disappearance of cordycepin does not affect the remarkable efficacy of Cordyceps sinensis.Therefore, these two kinds of effects of Cordyceps sinensis and Cordyceps militaris are similar, but the incomplete same bacterial classification of composition has complementarity.
Summary of the invention
Based on current situation, the present invention take taro as medium, when not adding other additive any, only taro is carried out expanding treatment, after sterilizing, Simultaneous vaccination Cordyceps sinensis and Cordyceps militaris carry out Mixed culture, finally obtain the health care taro of high cordycepin content and high bioactivity.The method is implemented simple, quality controllable, has wide application and development prospect.
