Description

The liquid fermentation medium making method of the little medicinal fungus of a kind of richness

Technical field

The present invention relates to a kind of culture medium prescription making method of medicinal fungus liquid fermenting, particularly relate to the liquid fermentation medium making method of the little medicinal fungus of a kind of richness, belong to the bio-pharmaceuticals production technical field.

Background technology

Medicinal fungus broad sense refer to that all can be used for the fungus of pharmacy, narrow sense refers to the macro fungi (gill fungus bacterium) for medicine.Wild have Cordyceps sinensis, cicada fungus, stone-like omphalia, a CNNS's skin umbrella etc.; At present, tame have glossy ganoderma, Poria cocos, umbellate pore furgus, rhizoma Gastrodiae, Phellinus, auricularia auriculajudae, a rainbow conk etc.These medicinal fungus have the applicating history of more than one thousand years in China, they are though effect is different, and maximum advantage, be also that their common ground has no side effect exactly.The functions such as modern medicine research shows, they are not only traditional beneficial gas, keep fit, get rid of illness, stimulate the menstrual flow, lengthen one's life, also tool strengthens body immunity, antitumor anticancer effect.Many edible mushroomss are with pharmaceutical use.

China utilizes fungi as the existing at least history in 2500 of medicine therapy.China the earliest medicine book Shennong's Herbal and the successive dynasties herbal medicine in record: the medicinal fungis such as glossy ganoderma, Poria cocos, umbellate pore furgus, Cordyceps sinensis.China's Resources of Medicinal Fungi is abundant, and identified just have a kind more than 200, to the medicinal fungi systematic research since the sixties in 20th century.Early stage work focuses on artificial culture research, as artificial cultures such as Poria cocos, hedgehog hydnum, glossy ganodermas, studies.Since the seventies, the exploitation of medicinal fungi have been used as medicine and have been developed into Industrial Submerged Fermentation from early stage use sporophore compatibility, physics, chemical process extracting effective components, the reconstruction structure composition, route of administration except oral, has also developed injection.Simultaneously, also done a large amount of work at aspects such as pharmacology, medicine, clinical experiment, pharmaceutical technologies.

The exploitation of medicinal fungus is generally to extract from the sporophore of natural or artificial culture at present, yet fruiting body yield is limited, and along with the development of liquid fermentation technology, the advantage of cultivating medicinal fungi by solution fermentation progressively embodies.Adopt liquid culture method to produce medicinal fungus mycelium and fermented liquid, not only the cycle is short, condition is simple, output is high, but also can improve the output of its biologically active substance by the optimization production condition, facilitates the extraction of purpose component.Therefore, be devoted to the mycelial artificial culture of medicinal fungus both at home and abroad always,, to shorten incubation time, save production cost.Occurred more medicinal fungus mycelium product on domestic market, mostly be liquid submerged fermentation and cultivate gained.

Selenium is a kind of essential trace element of humans and animals, is the important component part of plurality of enzymes, and selenium is the sweet skin peroxidase of paddy moon bright important component, and by redox, the protection microbial film is avoided infringement, keeps the normal function of cell.Selenium can also play strengthening immunity, protection cardiovascular, promote growth, antitumor, detoxifcation, regulate the function such as metabolism.The endemy that causes at the scarce selenium of China has Keshan disease and Kaschin-Beck disease.Yeast rich in selenium, for supplementing the some diseases successful that causes because lacking selenium, has very abundant nutritive ingredient in addition in yeast, can bring into play synergy.

The chromium element plays an important role in all Regular Insulin adjusting activities as a kind of micronutrient element of necessity, and it can help Regular Insulin to promote that glucose enters intracellular efficiency, is important blood sugar regulator.Aspect blood glucose regulation, particularly the diabetic subject there is important effect.It helps to grow, and the cholesterol concentration in blood is also had control action kou, may cause heart disease during shortage.

Magnesium elements, as the activator of enzyme, participates in the enzymatic reaction more than 300 kinds.Synthetic, the nucleic acid metabolism of glycolysis-, Fatty Acid Oxidation, protein etc. needs magnesium ion to participate in.It is only second to calcium, phosphorus in bone, be the necessary element of osteocyte structure and function, and to promoting bone growing and osteanagenesis, intensity and the density of keeping bone and tooth have vital role.

Magnesium, calcium, potassium ion are worked in coordination with and are kept nervimuscular excitability simultaneously.In blood, magnesium is too low or calcium is too low, and excitability all increases; Otherwise sedative effect is arranged.The most important thing is that magnesium can improve the vigor of sperm, strengthen male fecundity, magnesium is the male sex's " health-care extract ".

The relation of zinc element and brain development and intelligence, promote lymphopoiesis and mobility, epithelium and mucosal tissue are normal to keeping, defense against bacterial, Virus entry, elimination ulcer, promote wound healing, reduce the dermatosis such as acne and proofread and correct the sense of taste malfunctioning, improve appetite, strengthen the dark situation adaptive faculty etc.

Produce in medicinal fungus mycelium and fermentation liquor technique at liquid culture method, the formula of substratum is very crucial.Present rich little medicinal fungus liquid fermenting formula is nitrogenous source mainly with extractum carnis, peptone or common yeast powder greatly, take sucrose, glucose or rice as main carbon source, the component of formula lacks specific aim, cause the active principle content such as exocellular polysaccharide in mycelium, fermented liquid and medicinal rhzomorph, medicinal fungus acid not high, production cost rises.In fact, in the liquid bacteria mycelium fermentation process of the little medicinal fungus of richness, the nitrogen carbon sources such as extractum carnis, peptone, sucrose, glucose or rice are not only on the high side, and not suitable nitrogen carbon source, be difficult for therefore must designing and producing the liquid bacteria mycelium fermentation culture medium prescription of the high rich little medicinal fungus of a kind of inexpensive effect for mycelium absorbs.

Summary of the invention

Purpose of the present invention, design exactly a kind of with take the yeast fermentation broth enriched material as major nitrogen source, take rice, wheat, maize straw powder mixture as main carbon source, add simultaneously chromium, magnesium, zinc, four kinds of trace elements of selenium, the liquid bacteria mycelium fermentation culture medium prescription of the rich little medicinal fungus of the liquid bacteria mycelium fermentation culture medium prescription of the rich little medicinal fungus that is made.

The liquid fermentation medium making method of now introducing the little medicinal fungus of a kind of richness is as follows:

1) yeast fermentation broth enriched material: the yeast fermentation broth enriched material of selecting market supply;

2) preparation of carbon source component raw material: with rice, wheat, maize straw powder mixture according to mass ratio: mix at 1: 1: 2, be crushed to the 50-100 order, standby;
