Description

Cultivate the method for producing Cordyceps sinensis with silkworm
The present invention relates to cultivate the method for producing Cordyceps sinensis with silkworm.
Cordyceps sinensis is that Cordyceps fungus (Cordyceps sinensis) parasitizes the formed bacterium worm mixture in back on the Chinese caterpillar fungus bat moth insect body such as (Hepialusarmoricanus), main product is in the alpine scrub and high mountain steppe of height above sea level 3500~5000m such as Sichuan of China, Qinghai, Tibet, Yunnan, Gansu, with genseng, pilose antler is equally celebrated for their achievements is the three big famous and precious nourishing diseases prevention Chinese medicinal materialss of China.But, because Chinese caterpillar fungus bat moth life cycle of the natural host insect of Cordyceps fungus is long, and the many natural enemies of many diseases, i.e. the worm source deficiency of natural propagation.Again it, environmental pollution in recent years, grassy marshland is desertified, artificial coyoting is excessively too early dug excessively and the chance that immature Chinese caterpillar fungus reduced infect the host etc., the Cordyceps sinensis quality and quantity is sharply descended, and its natural resources pursues exhausted, and the producing region that has has been dug less than Cordyceps sinensis, endangered state can not satisfy the growing demand in domestic and international market far away.
In order to remedy the huge breach between the Cordyceps sinensis supply and demand, take the method for artificial culture to produce the surrogate of Cordyceps sinensis at present.The method of its artificial culture mainly contains two classes: 1) adopt the artificial eye-liquid cultural method, obtain the mycelia and the tunning of Cordyceps fungus, make product-feed markets such as " zhiling capsuleses ".But there are the easily assorted problems such as pharmacology medicine instability that bacterium mixes, effective constituent is easily decomposed destruction, mycelia and tunning in these class methods, and this product did not both have " grass " not have " worm " yet, be not Cordyceps sinensis in essence, far apart with natural Cordyceps sinensis.2) artificial breeding Chinese caterpillar fungus bat moth larvae, the artificial inoculation Cordyceps fungus is to cultivate Cordyceps sinensis again.But these class methods exist the Chinese caterpillar fungus bat moth life generation cycle long, the life restraining factors are many, raise and depend on natural condition mostly, be difficult to finish well digenesis, expense cost height, problem such as of poor benefits indoor, do not see so far to be applied to production.
The objective of the invention is to substitute Chinese caterpillar fungus bat moth larvae with silkworm (Bombyx mori L.), after Cordyceps fungus made the physics and chemistry biological processes, be inoculated in the silkworm body, simulate natural surroundings again, make Cordyceps fungus infect parasitic silkworm body and grow the method for cultivate producing Cordyceps sinensis with silkworm of stroma.
In order to achieve the above object, the technological method of the present invention's employing is as follows:
A kind of is to gather superfine Cordyceps sinensis, after 0.1~0.2% mercuric chloride liquid surface sterilization, cuts tissue block and places on the PDA substratum and cultivate, and isolates Cordyceps fungus; Be in the tender mycelia of Cordyceps fungus children of logarithmic phase with 4~8mg/mL Driselase enzyme liquid oscillation treatment, isolate protoplastis; Place 15W ultraviolet lamp to shine 20~60sec down protoplastis, obtain that silkworm is had the mutant that infects parasitics at a distance of 10~30cm; With 30~40%PEG-Ca ++Be fusion-inducing agent, to have the protoplastis fusion of the protoplastis and the former Cordyceps fungus of the Cordyceps fungus mutant that infects parasitics to silkworm, with the cordycepin of mycelia, cordycepic acid, Cordyceps polysaccharide content with to the infection parasitics of silkworm is indication trait, therefrom cultivates to filter out not only to have kept the original proterties of Cordyceps fungus but also can infect parasitic silkworm body and the Cordyceps sinensis bacteria strain of growth well; The Cordyceps sinensis bacteria strain is contained in 1000mL distilled water be inoculated in the silkworm body after cultivating breeding on the substratum of 100~150g potato, 30~40g peptone, 30~40g glucose, 1g dipotassium hydrogen phosphate, 0.5g sal epsom, 10~15g extractum carnis, 20~30g fresh silkworm chrysalis powder, 17~20g agar, pH5.0; Under 10~30 ℃ of temperature, humidity 70~100%, the clean environment of illumination 6~24h/ day, protect, the Cordyceps sinensis bacteria strain is fully grown in the silkworm larva body or in the silkworm chrysalis body also grow stroma at last.Treat to gather in the crops when stroma grows to 5~7cm, dry under 50~60 ℃, be used for making into new drug.
Another kind is to gather superfine Cordyceps sinensis, after 0.1~0.2% mercuric chloride liquid surface sterilization, cuts tissue block and places on the PDA substratum and cultivate, and isolates Cordyceps fungus; Be in the tender mycelia of Cordyceps fungus children of logarithmic phase with 4~8mg/mL Driselase enzyme liquid oscillation treatment, isolate protoplastis; From the Bombyx Batryticatus body, isolate silkworm cause of disease muscardine, be in the tender mycelia of silkworm cause of disease muscardine children of logarithmic phase, isolate protoplastis with 4~8mg/ml Driselase enzyme liquid oscillation treatment; With 30~40%PEG-Ca ++Be fusion-inducing agent, the protoplastis of silkworm cause of disease muscardine and the protoplastis of Cordyceps fungus are merged, with the cordycepin of mycelia, cordycepic acid, Cordyceps polysaccharide content with to the infection parasitics of silkworm is indication trait, therefrom cultivates to filter out not only to have kept the original proterties of Cordyceps fungus but also can infect parasitic silkworm body and the Cordyceps sinensis bacteria strain of growth well; The Cordyceps sinensis bacteria strain is contained in 1000mL distilled water be inoculated in the silkworm body after cultivating breeding on the substratum of 100~150g potato, 30~40g peptone, 30~40g glucose, 1g dipotassium hydrogen phosphate, 0.5g sal epsom, 10~15g extractum carnis, 20~30g fresh silkworm chrysalis powder, 17~20g agar, pH5.0; Under 10~30 ℃ of temperature, humidity 70~100%, the clean environment of illumination 6~24h/ day, protect, the Cordyceps sinensis bacteria strain is fully grown in the silkworm larva body or in the silkworm chrysalis body also grow stroma at last; Treat to gather in the crops when stroma grows to 5~7cm, dry under 50~60 ℃, be used for making into new drug.
