Description

The two-way solid fermentation method of ganoderma lucidum-dregs of a decoction and application using air pressure pulsation
Technical field
The two-way solid fermentation method of ganoderma lucidum-dregs of a decoction and the application that the present invention relates to the use of air pressure pulsation, belong to micro- life Object fermentation technical field.
Background technique
Ganoderma Lucidum is that a kind of nutrition and health care is worth high macro-fungi, have improve immunity of organisms, it is anti-oxidant, Macrophages phagocytic capacity and the multiple efficacies such as antitumor are improved, is incorporated into Chinese Pharmacopoeia already, is used for health food development.Spirit Sesame polysaccharide and ganodenic acid are most important active materials in ganoderma lucidum.Radix Astragali is leguminous mongolian scutellaria, Astragalus membranacus or more The dry root of sequence rock Radix Astragali has QI invigorating qi-restoratives, toxin expelling myogenic and other effects, and market demand is huge, the Huang that the whole nation generates every year Up to ten thousand tons of 4-6 of the stilbene dregs of a decoction.Many studies have shown that still containing various active substance, such as Astragaloside IV and Huang in astragalus root dregs Recovery rate of the astragalus polysaccharides in alcohol extracting medicinal material only accounts for the 72.1% and 52.6% of Milkvetch Root.Radix Salviae Miltiorrhizae is Lamiaceae plant Radix Salviae Miltiorrhizae Dry root and rhizome have activating microcirculation and removing stasis medicinal, cool blood to disappear carbuncle and other effects, and tanshinone is the main active substances in Radix Salviae Miltiorrhizae, at present second Alcohol extracting efficiency is lower than 10%, therefore, still containing the active constituent of abundant residues in the Radix Salviae Miltiorrhizae dregs of a decoction.Currently, China's Chinese medicine slag is big It is dropped, this not only causes the wasting of resources, also creates serious environmental pollution more.
Bi-directional fermentation technology be by medicinal fungi (ganoderma lucidum etc.) as fermenting microbe and drug matrices (have certain activity at The Chinese medicine or the dregs of a decoction divided) fementative composition is constituted, on the one hand change the pharmacological property ingredient of matrix, another party by fungi growth metabolism Cucumber in the drug matrices of face also can growth to fungi and metabolism have an impact, there is amphicheirality, thus to crude drug/ The dregs of a decoction play synergy, expand the effect used and be attenuated.Bi-directional fermentation is the current most promising approach of dregs of a decoction resource utilization.
Solid fermentation is the common method of microbial fermentation, compared with liquid fermentation, has water-saving, energy saving, fermentation process Advantages, the filamentous fungi such as Ganoderma Lucidums etc. such as rare waste material generates, and environmental pollution is small are particularly suitable for solid fermentation.Ganoderma lucidum at present The solid fermentation of bacterium uses the methods of tray formula, column type, stirring-type and drum-type substantially.However, static culture there are heat, Oxygen transmitting is difficult, causes content temperature, humidity and thalli growth seriously uneven, and raw material availability is low, and uses stirring Mode then causes energy consumption excessive, destroys mycelium, influences thalli growth metabolism.Air pressure oscillation fermenter is with gas State, solid medium are static state, pass through a kind of technology of the pressure oscillation regulating and controlling microbial solid state fermentation of gas phase, main advantage Including periodic pressure oscillation can provide sufficient oxygen to the mycelia inside particle and will be present in inside particle Metabolic heat and the discharge in time such as dioxy salt dissolving, reach the environment uniformity around thallus on small scale, in addition, pressure oscillation can So that solid state substrate is kept loose, expanded space for mycelial mass propagation, mycelial growth is vigorous inside and outside the layer that ferments, raw material Utilization rate is high, and is in honeycomb after fermentation substrate drying, easily crushes.So far, pressure fluctuation is sent out as a kind of reinforcement solid-state Ferment mass transfer, heat transfer effective means, be applied to bacillus thuringiensis, bacillus subtilis, muscardine, P. aeruginosa The solid state fermentation of the microorganisms such as bacterium, Penicillium notatum, black-koji mould and Trichoderma, however yet there are no report in Ganoderma Lucidum solid state fermentation Road.
Summary of the invention
The first object of the present invention is in view of the deficiencies of the prior art, to provide a kind of utilization air pressure pulsation solid hair Ferment produces ganoderma lucidum-dregs of a decoction bi-directional fermentation mycoplasma method, to promote Ganoderma Lucidum to grow, improves main active substances polysaccharide and triterpene Yield.
To achieve the above object, the invention adopts the following technical scheme:
A method of ganoderma lucidum-dregs of a decoction bi-directional fermentation mycoplasma being produced using air pressure pulsation solid fermentation, including following Step:
1) preparation of seed liquor: lucid ganoderma fungus slant strains being inoculated in the cooling liquid seed culture medium that sterilized, In 25~30 DEG C of 4~8d of culture to get lucid ganoderma fungus seed liquor;According to the needs of inoculation, which can be expanded by fermentor Big culture is secondary seed solution or three-level seed liquor;
2) preparation of solid fermentation culture medium: solid base and nutrient solution are stirred according to the mass ratio of 1:1~1:3 It is even, it puts into pressure fluctuation solid-state fermentation tank, 30~60min of sterilization treatment is under conditions of 121 DEG C~125 DEG C to get solid Fermentation medium;
