Description
Technical field
The invention belongs to technical field of bioengineering.Be specifically related to a kind of production method of zymotechnique and polysaccharide peptide thereof of Agaricus blazei Murrill.
Background technology
Agaricus blazei Murrill claims Brazilian mushroom, Xiao Song mushroom again, is the rare edible fungus of a kind of precious cutting edge of a knife or a sword.Its sporophore contains the multiple amino acids of various active compositions such as polysaccharide and sterols and various trace element, needed by human, to tumour, hemorrhoid, neurodynia tool curative effect, the effect that also has reducing blood-fat and decreasing cholesterol is a kind of medicinal fungi that the exploitation future is arranged very much.Declared patent in the U.S., Japanese multinomial achievement in research.
The main active ingredient of Agaricus blazei Murrill is an Agaricus Blazei Murrill polysaccharide, based on glucose, is primary structure with β-(1 → 3) dextran with β-(1 → 6) side chain in the polysaccharide component.Result of study shows, Agaricus Blazei Murrill polysaccharide is mainly by activating body immune system, strengthen the phagolysis of scavenger cell, stimulate the formation of Interferon, rabbit, activate natural killer cell in the body, promote the generation of immunoglobulin (Ig), interleukin-, improve lymphocytic transformation efficiency etc. and bring into play its antitumor action, stronger anti-chemomorphosis effect is arranged on gene level, can be used for behind chronic hepatitis B and the concurrent chemoradiotherapy of malignant tumor weak, oligoleukocythemia, the complex therapy that immunologic function reduces.
Summary of the invention
The objective of the invention is to improve production technique, improve the output of mycelial yield and polysaccharide peptide.
The invention provides a kind of production method of zymotechnique and polysaccharide peptide thereof of Agaricus blazei Murrill.This method comprises the following steps: the breeding and the feature of (1) Agaricus blazei Murrill
Obtain the pure strains A B103 of Agaricus blazei Murrill with tissue isolation, it is seeded on PDA or the wort constant inclined surface substratum, after 7～10 days, place the refrigerator about 4 ℃ to preserve standby in 25～28 ℃ of constant temperature culture.Adopt the ultraviolet mutagenesis method that hyphal cell is carried out mutagenesis, the uv irradiating distance is 20～30cm, and irradiation time is 5～15 seconds.The mycelial growth ability of primary dcreening operation mutagenic fungi on solid medium sieved mycelial growth amount and polysaccharide peptide output in the mutagenic fungi liquid medium within again, obtains quality strains AB103-51.This strain classification called after Brazilian mushroom (Agaricus blazei Murrill) Agaricus blazei, this bacterial strain have been stored in Chinese microbial preservation management committee common micro-organisms center on July 16th, 2002, the preservation center be numbered CGMCCNo.07722001325B.And detect the result on July 16th, 2002 and be survival.
Solid culture is with 40～50% straw (or wood chip, cotton seed hull), 1% sucrose or glucose, 10～20 wheat bran or rice bran, 1% gypsum or lime carbonate, poach, and water content 60%, the PH nature, bottled, at 1.5kg/m
2Down sterilization 1 hour of pressure, after the cooling, shake-flask seed is inoculated in the solid medium under aseptic technique, 22～26 ℃ of culture temperature, mycelium was covered with full bottle in 20～30 days.After original hase is sprouted, reduce by 22～25 ℃ of cultivation temperature, keep suitable humidity, illumination and ventilation, after 30～40 days, the sporophore maturation; (2) the zymotechnique flow process of bacterial strain
The present invention adopts the aerobic fermentation method to produce the Agaricus blazei filament, and fermention medium is with low cost, and fermentation period is short.The zymotechnique flow process is as follows:
Slant strains or eggplant bottle bacterial classification → shake-flask seed → 50-100L
3Seeding tank (one-level) → 500-1000L
3Seeding tank (secondary) → 5000-10 ton fermentor tank.
Loading amount 75～the 150ml/250ml of shake-flask seed or 150～150ml/250ml substratum, reciprocating type shaking table hunting speed 80～150 times/minute, or 100～200 rev/mins of rotary shaking table hunting speeds, 24～28 ℃ of culture temperature.Incubation time 2～3 days.Seeding tank and fermentor tank charging capacity 50～70%, inoculum size 8～10%, stirring velocity 100～200rpm, air flow 1: 0.5～1: 1v/vmin, fermented incubation time 4～7 days.Along with fermented incubation time prolongs, substratum is become clearly gradually by muddiness.Reducing sugar, ammonia-state nitrogen, PH reduce gradually in the fermented liquid, and mycelial biomass constantly increases, and polysaccharide peptide output reaches and stops fermentation when the highest during to the 5th～6 day.(3) extraction of Agaricus Blazei Murrill polysaccharide peptide
The polysaccharide peptide extraction process of Agaricus blazei Murrill AB103-51 of the present invention is: Agaricus blazei Murrill fermented liquid sintered filter funnel suction filtration, and separate fermentation liquid and mycelium, factory can use board and frame machine separate fermentation liquid and mycelium.Wet mycelium is added 10～20 times of water loggings bubble spend the night,, filter, add 0～4 ℃ of precipitation of 95% ethanol 8～10 hours of 2～5% times after filtrate is concentrated, the dry Agaricus Blazei Murrill polysaccharide peptide that gets with 90～100 ℃ of water-bath refluxing extraction 2～5 hours.
The AB103 bacterial classification that obtains through tissue isolation of the present invention, the sporophore meat, most single, grow thickly individually.The cap semisphere is extremely open and flat, diameter 3～10cm, and light brown to brown, there is fibrous scale on the cap surface, and there is the velum fragment at the edge.The nearly cylindrical cap central authorities of being born in of stem, the initial stage is solid, the middle and later periods is loose to hollow.Collarium easily comes off.The sporidium light red is to brown, and is smooth, short oval.The mycelia branch has tabula, no clamp connexion.The strains A B103-51 of physical mutagenesis gained cultivates on solid wood chip bran mass, and its sporophore shape is identical with natural entity.
The cultivation proterties of Agaricus blazei Murrill bacterial strain AB103-51 of the present invention is: 1. is seeded on the potato dextrose agar, and 24～28 ℃ of temperature, it is vigorous to grow, and mycelium pure white, velvet-like is inoculated ten days colony diameters and is reached 15-20mm.2. be seeded on the sawdust medium, its cultural characteristic as mentioned above.3. when shaking bottle shaking culture, use reciprocating type shaking table, hunting speed 80～150 times/minute, or rotary shaking table, 100～200 rev/mins of hunting speeds form bacterial strain, and when bacterium formed in a large number, fermented liquid became clear by muddiness, and viscosity increases gradually, distributes strong fruital flavor.4. in fermention medium, when cultivating 5～6 days, mycelial growth and polysaccharide peptide output reach the highest, can stop fermentation.
The feature of Agaricus blazei mycelium polysaccharide peptide is: 1. polysaccharide peptide, and polysaccharide content is 20～40%, protein content is 15～30%.2. grey is to the beige powder.3. major ingredient all is a beta-glucan.4. infrared extinction spectrum peak position is 883～892cm
