Description

The artificial culture method of Cordyceps kyushuensis and the application of sporophore thereof
The present invention relates to a kind of artificial culture method of microbial fungi, the particularly new Chinese record species of finding first in China---the artificial culture method of Cordyceps kyushuensis (Cordyceps KyushuensisY.Kobayasi) and the application of sporophore thereof.
Cordyceps is commonly used and common fungi, and wild Chinese caterpillar fungus has multiple pharmacologic action, and tonic effect has become traditional precious Chinese medicine, extremely human consumer's favor.But because the very shortage of its wild resource, and growing environment is special, and wild amount is limited, adds excessively and excavates, and far can not satisfy the demands.For this reason, many scientific workers are being devoted to the artificial culture of Chinese caterpillar fungus, attempt to solve the problem of existing wild Chinese caterpillar fungus shortage of resources.Artificial culture method according to some Cordyceps sinensis fungus of relevant bibliographical information mainly contains: " industrial process of Cordyceps mycelium " (patent No. 85107991) and " cordyceps species 814 seed selections and zymotechnique thereof " (patent No. 85102231), all be to carry out deep layer with its isolating pure strain to cultivate, obtain mycelium with zymotechnique, up to the present, it has only been finished asexual generation, still can not artificial culture." artificial culturing method of silkworm chrysalis Cordyceps sinensis " (patent No. 87106987) is to utilize the wheel skill bacterium of Cordyceps militaris (L.) Link. to be inoculated on the solid medium, treats that mycelia is long to a certain degree putting into silkworm chrysalis again, allows its natural infection and grows sporophore.Its incubation time is long, and sporophore and pupal cell one is reinstated when being used as medicine, because of pupal cell is big, sporophore only account for its about 1/5th, the intravital effective constituent major part of pupa has been transformed on the sporophore, historical facts or anecdotes border effect is affected." method of artificial culture Brazil Chinese caterpillar fungus " (90109380.7) are to utilize Brazilian Cordyceps to be inoculated on the silkworm, and obtain worm, bacterium combination.Its application still is not pure sporophore." Chinese caterpillar fungus obviously increases the spleen weight of mouse, and discovery causes composition that spleen heavily increases at stroma, and polypide is invalid according to " Tianjin pharmacy " 98 years the 10th the 1st phase of volume." visible Chinese caterpillar fungus be used as medicine drug action mainly in sporophore, be not polypide.China in " China is by the hair spore and finish the technology of perfect stage Cordyceps sinensis " (88103453) is the anamorph of Cordyceps sinensis by the hair spore, its bacterial classification will be through the generation spore that cultivates one's ability of some months, contaminate host's Hepialus oblifurcus Chu et Wang larva with asexual spore again, after 10 degree left and right sides subzero treatment, 18 ℃ of left and right sides heat insulating culture, grew stroma through two months, whole culture cycle is longer.Because the abortion phenomenon in its spore exists, thereby germination rate is low, inoculation back parasitic rate is also low, and sporophore is difficult to form, and therefore influences it and applies.
The inventor once disclosed the tame method of Cordyceps militaris (L.) Link. (having another name called Cordyceps militaris) in " method of artificially cultivating north Chinese caterpiller fungus daughter vaccine " (93105056.1), " seed selection of cordyceps militaris excellent species and high yield cultivating method " (94110061.8), " Cordyceps militaris (L.) Link. high yield cultivating method " patent documentations such as (97105853.0).This method utilization is the solid medium of major ingredient with the rice, successfully cultivates Cordyceps militaris (L.) Link., but its matrix is single, the nutritional status that has broken away from primary object can not satisfy the needs of sporophore growth, spawn degeneration fully, the problem that pharmacologically active goes down can occur, effectively nutrient composition content is low.Therefore, above-mentioned artificial culture method can not guarantee that sometimes bacterial classification is stable, has increased difficulty for the work of carrying out cultured continuously Cordyceps sporophore.296 pages of " fungus system " 2000 the 19th the 2nd phases of volume " new Chinese record species-kyushu aweto " disclosed in addition, it is a kind of Cordyceps on greenish brown hawk moth (Clanis Bilineata Walker) the larva body that parasitizes in Shenyang Eastern Mountain Area collection, is accredited as kyushu aweto (Cordyceps Kyushuensis Y.Kobayasi).Its outward appearance and morphological specificity are summarized as follows: sporophore is born on the shoestring (rhizomorph) that forms from killing bean hawkmoth larva, shoestring white.Stroma is orange red, high 1.7-8.6cm, and diameter 0.2-0.6cm gives birth in the perithecium half, and is avette, 367-495 * 260-316 μ m.Ascus is cylindrical, diameter 3.5-4.8 μ m.Secondary thecaspore short cylindrical, 3.9-5.4 * 1.0-1.2 μ m.But the report that does not still have kyushu aweto artificial culture method on the at present domestic and international open source literature.
Purpose of the present invention just is to provide a kind of artificial culture method of new Chinese record species-Cordyceps kyushuensis and the application of sporophore thereof, this method has effectively overcome existing can not carrying out of existing in the Chinese caterpillar fungus technology problems such as total man worker cultivates, incubation time is grown, the spawn degeneration phenomenon is serious of cultivating, it is stable to have bacterial classification, with short production cycle, can be continuously, produce in batches, the effective high advantage of nutrient composition content, adopt pure sporophore to be used as medicine, its consumption is few, and the preparation medicinal effect is remarkable.
The object of the present invention is achieved like this: this method is earlier the wild bacterium of Cordyceps kyushuensis (Cordyceps Kyushuensis Y.Kobaygasi) to be carried out monospore or single bacterium colony purifying, bacterial strain behind the purifying is made on the substratum that the liquid spawn tieback is main component to the live body killing bean hawkmoth larva of raising down with the aseptic condition of surface sterilization or is on the substratum that is mixed of main component with live body killing bean hawkmoth larva lyophilized powder, paddy rice, nutritive medium, natural infection under suitable culture condition continues to cultivate until growing the kyushu aweto sporophore;
Employed substratum live body killing bean hawkmoth larva is that 3 orders-5 of raising under the aseptic condition make larva, its surface sterilization is inserted liquid spawn, natural infection 30-40 days, treat that mycelia is full of in its body, cover 2-3 centimetre of habitat soil, continue to cultivate until growing the kyushu aweto sporophore through sterilization.
The employed substratum substratum that is mixed, the weight ratio of each component is respectively in per hundred parts of substratum that are mixed: live body killing bean hawkmoth larva lyophilized powder 3-5 part that aseptic condition is raised down, paddy rice 97-95 part, nutritive medium is 1.4 times of above-mentioned raw materials gross weight, be mixed and insert liquid spawn behind the medium sterilization, natural infection under the thermophilic culture condition treats that mycelia is covered with media surface substantially and extends downwards, give the scattered light irradiation, ventilate, until growing the kyushu aweto sporophore.
Because the substratum that adopted of artificial culture method of the present invention is that the live body killing bean hawkmoth larva with artificial breeding under the aseptic condition is a main component, this larva body is big, nutritious, and there is not the intravital assorted bacterium of wild live larva in the body, so when wild bacterium is carried out the purifying breeding, not only can guarantee to select the pure strain identical, and continue to grow the artificial culture kyushu aweto sporophore identical in the culturing process with natural kyushu aweto sporophore in inoculation with wild kyushu aweto.This method is compared with other Chinese caterpillar fungus artificial culture method, with short production cycle, bacterial classification is stablized, and significantly improves the infection rate of Cordyceps kyushuensis, and it is cultivated surviving rate and grow the sporophore rate and all reaches more than 100%, transformation efficiency is up to 168.3%, also lays good basis for continuous batch production, high yield.Can prevent effectively that also pharmacologically active from going down.Through Shenyang Inst. of Applied Ecology, Chinese Academy of Sciences and the test of new Chinese medicine development center, Liaoning Province, its result shows: the stroma that artificial culture grows is through section and microscopic examination, its formalness and the internal feature all feature with natural kyushu aweto are close, see table 1 for details:
