A kind of be host artificial culture Pupa bombycis Periostracum cicadae with silkworm pupa method
Technical field
The method that the invention belongs to cultivate Periostracum cicadae, is specifically related to a kind of with silkworm pupa for host artificial culture Pupa bombycis Periostracum cicadae
Method.
Background technology
Periostracum cicadae (Cordyceps cicadae) is that Clavicipitaceae University of Science and Technology Cicadae grass (Cordyceps cicadae Shing) is parasitic
Stroma on the Cicadae nymph of cicada mountain and the complex of nymph corpse, be the traditional a kind of rare Chinese medicine of China.In
State, Periostracum cicadae is used as traditional Chinese crude drug and food has had more than 1500 year, far away early than Cordyceps.Modern medicine study table
Bright Periostracum cicadae composition Han various active, has treatment convulsion in childhood, antitumor, analgesia and calmness, improves renal function, resisting fatigue, exempts from
The functions such as epidemic disease regulation, are a kind of valuable ingredients of Chinese medicine close with Cordyceps, can be as the succedaneum of Cordyceps.
Periostracum cicadae market demand increases day by day, but the specific ecological environment of Periostracum cicadae growth needs and host insect, natural
The rate of output is relatively low, adds people and excavates the most in a large number, and resource reduces increasingly.In order to meet market and clinical demand, in recent years
Coming, scientific research personnel has carried out artificial culture's research of Periostracum cicadae, and makes some progress.At present, have some both at home and abroad to close
Open report in Periostracum cicadae artificial culture technology.Such as, " cultural method (CN103392500A) of a kind of Periostracum cicadae ", Cicadae is intended green grass or young crops

After, 20 DEG C-28 DEG C cultivations obtain Periostracum cicadae in 2-3 week.
Silkworm pupa nutritional labeling is the abundantest, and tradition utilizes and mainly develops into various food and health product.In recent years,
Pupa bombycis cultivation Cordyceps militaris (L.) Link. is increasingly becoming silkworm industry multipurpose and utilizes the study hotspot in field, and " silkworm chrysalis Cordyceps sinensis wine " is exactly with silkworm chrysalis Cordyceps sinensis
Form for major ingredient.But, up to now, the most do not use the method that Pupa bombycis cultivates Periostracum cicadae.
Summary of the invention
Goal of the invention: the problem existed for prior art, the invention provides a kind of artificial with silkworm pupa for host
The method cultivating Pupa bombycis Periostracum cicadae.The present invention uses silkworm living silkworm chrysalises to be that host cultivates Pupa bombycis Periostracum cicadae, and nutritional labeling is high, nontoxic,
Can develop into various food and health product, edible safety is reliable;The method that the present invention cultivates Periostracum cicadae with silkworm pupa, cultivates week
Phase is short, and technical matters is easy, it is adaptable to large-scale production.
Technical scheme: to achieve these goals, a kind of with silkworm pupa for host artificial culture silkworm as described herein
The method of pupa Periostracum cicadae, comprises the steps:
(1) from wild Periostracum cicadae, separate Periostracum cicadae bacterial strain, by Periostracum cicadae strain culturing to growing mycelium, then carry out bright
Dark alternate culture, after covering with spore, washes down spore, makes Periostracum cicadae spore suspension;
(2) silkworm living silkworm chrysalises body surface is carried out disinfection;By Periostracum cicadae spore suspension, silkworm pupa is infected;
(3) silkworm pupa that will have infected, cultivates hardening to Pupa bombycis, and white hypha body occurs in internode;
(4) by hardening Pupa bombycis, it is placed in gnotobasis, carries out light and shade alternate culture.
Further, step (1) described by Periostracum cicadae strain culturing to growing mycelium for Periostracum cicadae inoculation is solid in PDA
In body culture medium, 20-22 DEG C of light culture 8-10 days is to growing mycelium.
Further, step (1) is described is washed down spore as to be washed by spore by the sterilized water of 0.03-0.07% Tween 80
Under.
Further, step (1) described light and shade alternate culture concretely comprises the following steps 22-24 DEG C of light and shade alternate culture, and the cycle is
12-14h, intensity of illumination 250-350Lx, humidity 85%-95%, incubation time is 10-12d;The alternately training of step (4) described light and shade
Supporting and concretely comprise the following steps 20-24 DEG C of light and shade alternate culture, the cycle is 10-14h, intensity of illumination 150-400Lx, humidity 85%-95%,
Incubation time is 10-25d.This growth conditions simulates wild Periostracum cicadae natural growthing condition, and the Periostracum cicadae obtained not only profile is with wild
Periostracum cicadae is similar, and quality is suitable with wild Periostracum cicadae.
Further, step (1) described Periostracum cicadae spore suspension concentration is 104-107Individual/mL.
Further, described carry out silkworm pupa of step (2) infects for injecting 5-with syringe at Pupa bombycis subcutaneous tissue
10ul Periostracum cicadae spore suspension, puts in sterilized culture dish.
Further, described carry out silkworm pupa of step (2) infects for Pupa bombycis is placed in Periostracum cicadae spore suspension immersion
Take out after 10-15min, put in sterilized culture dish.
Further, described carry out silkworm pupa of step (2) is infected for being sprayed at Pupa bombycis body surface by the method for spraying
Periostracum cicadae spore suspension, puts in sterilized culture dish.
Further, step (3) described cultivation is hardening hardening to Pupa bombycis for 20-24 DEG C of light culture to Pupa bombycis.
Further, step (4) described gnotobasis is to boil sand or the aseptic plastic box of 0.5-1.5h sterilizing.
Beneficial effect: compared with prior art, the method that the present invention is host artificial culture Pupa bombycis Periostracum cicadae with silkworm pupa
Having the advantage that employing silkworm living silkworm chrysalises is that host cultivates Pupa bombycis Periostracum cicadae, nutritional labeling is high, nontoxic, can develop into each
Planting food and health product, edible safety is reliable;The breeding method of the present invention, cultivation cycle is short, and technical matters is easy, it is adaptable to big
Large-scale production;One aspect of the present invention is that the exploitation of Pupa bombycis resource high added value provide new way, is conducive to improving and supports
The economic benefit of silkworm industry;On the other hand, increase due to Cordyceps demand in recent years, cause Cordyceps price to ramp, enter
And promoted the demand to Periostracum cicadae, simultaneously along with Periostracum cicadae environmental destruction, Periostracum cicadae resource will face the problem of exhaustion, because of
This, the present invention has potential social benefit to protection Periostracum cicadae wild resource, maintenance ecological balance.
