Abstract
The invention provides a culture medium and a preparation method of male agaric mycelium, and a method for culturing the male agaric mycelium by using the culture medium. The culture medium comprises rice and a culture solution. As rice is used as the raw material of the culture medium, the raw material is available and is economic, the operation is simple, and the effect is good.
Description
Technical field
The present invention relates to edible mushrooms and cultivate the field, relate to specifically a kind of substratum and cultural method of phellinus igniarius mycelium.
Background technology
Bao nurse Phellinus (Phellinus baumii) is commonly called as Phellinus mushroom, mulberry ear, is a kind of perennial medicinal fungi of developing in recent years, records the earliest in the LI Shi-Zhen Compendium of Material Medica.Traditional Chinese Medicine thinks that Phellinus is sweet, flat, and bitter, suffering are returned liver, urinary bladder channel, be used for the treatment of that metrorrhagia, blood are drenched, prolapse of the anus is rushed down blood, under band, amenorrhoea, diarrhea due to hypofunction of the spleen etc.Numerous experimental studies show, the polysaccharide in Phellinus and flavonoid compound have important biological activity, are playing an important role aspect treatment cancer, liver protecting, enhancing immunity, neural reparation.
Free radical is the metabolic product of human body, and generally, human body has the ability to remove the free radical that self produces, and still along with the aging of human body, the ability of removing free radical weakens.If the free radical that produces can not in time be removed, will accelerate body aging, even make human body generation pathology etc.Existing studies show that: the polysaccharide in Medicinal Fungus Phellinus igniarius and Flavonoid substances have good antioxygenation; But present research focuses mostly on aspect the research of Phellinus fruiting body extract and liquid fermenting, and less to the research of solid fermentation phellinus igniarius mycelium and antioxygenation thereof.Wild sporophore mainly is distributed in the forest zones such as Heilungkiang, Shaanxi, and the resource standing stock are rare, cause expensive owing to yielding poorly.The Phellinus sporophore mainly obtains by artificial culture at present, but the artificial culture cycle is long, needs larger manpower financial capacity to drop into.By contrast, fermentation technique has short, the advantage such as controllability good, experimental situation is simple of cycle, is the good approach that obtains the Phellinus secondary metabolite.And liquid fermenting easily pollutes in the process of cultivating, and can not reach the biomass of expection in certain incubation time, bad control artificially in culturing process.
Summary of the invention
One of purpose of the present invention is to provide a kind of substratum of phellinus igniarius mycelium, and this substratum comprises following component:
Rice and nutrient solution, wherein the volume (ml) of the weight of rice (g) and nutrient solution is than being x:(x+(0-30), x 〉=10 wherein;
Wherein nutrient solution contains: 2.5% glucose, 0.3%KH
2PO
3And 0.15%MgSO
47H
2O。
Above-mentioned substratum is prepared by the following method:
Configuration nutrient solution (2.5% glucose, 0.3%KH
2PO
3, 0.15%MgSO
47H
2O), rice is placed in nutrient solution, autoclaving.
The present invention also provides a kind of method of utilizing above-mentioned culture medium culturing phellinus igniarius mycelium, and the method comprises the steps:
The female kind of Phellinus is inoculated on above-mentioned substratum, is placed in 26 ℃ of biochemical cultivation cases and cultivates, growth cycle 25-30 days;
With cultured mycelium together with substratum as for drying in 30 ℃ of convection oven.
Phellinus igniarius mycelium after above-mentioned rice medium fermentation has oxidation resistant biological action, can be used as foodstuff additive and uses, and improves Nutritive value of food.
Innovation of the present invention:
1, use substratum of the present invention to cultivate, liquid culture has advantages of convenient and easy, save energy, is difficult for polluting relatively.
2, substratum of the present invention, adopt rice as raw material not only material easily get, and very economical, respond well.Very large in the energy consumption of liquid culture medium power, and the present invention cultivates only need standing cultivation at a certain temperature of bacterial classification, save the energy, and growth conditions also is better than liquid culture.Find by anti-oxidant experiment simultaneously, the mycelium of cultivation has stronger antioxidant effect.Nowadays foodstuff additive are subject to extensive concern, and rice is as a kind of food of nutrient safe, and the mycelium of cultivation can be used as additive and improves Nutritive value of food.
