Description
Technical field
The present invention relates to a kind of antivirus microbe additive for silkworm.The invention still further relates to the preparation method of this microbe additive.
Background technology
Silk is produced, and in existing more than the 5500 year history of China, is the traditional specialty industries of China, also is a kind of special goods that can monopolize the international market in China's export abroad trade.To the expanding economy of silkworm industry, governments at all levels are all paid much attention to, and scientific and technological circle breed silkworms to science and also carried out continuous research and discussion, and at mulberry, silkworm breeding, aspects such as flacherie control have obtained very big progress.But in the sericulture process, still often outbursts such as viral, bacteriosis that silkworm is infected through infection of digestive canal or through foreign object and enteron aisle disease, and there is not the good recipe of control, have a strong impact on silkworm and survive growth, be placed on small straw bundles to spin cocoons, cocoon and cocoon yield and silk quality, also affect silkworm raiser and silk export processing economic benefit of enterprises.
Be engaged in that silkworm is already studied or the practice of breeding silkworms is all known: bacteriosis is easily controlled, and viral disease is difficult anti-.Silkworm is in case morbidity, treat lately, leans on chemotherapy, and it produces little effect, particularly viral disease: as disease of digestive tract, hematologic disease, past medical help at all.As seen, the drug therapy after the silkworm morbidity is passive, and the also inaccessible reduction disease rate of dying increases cocoon yield, improves the purpose of silk quality.
Therefore, pressed in this area and can initiatively effectively strengthen silkworm antibody, anti-bacteria and anti-virus reduces the disease rate of dying, and increases the amount of cocoon production, improves the silkworm of silk quality and uses complex microorganism additive.
Summary of the invention
The objective of the invention is to overcome above-mentioned existing disadvantages of background technology part, and a kind of antivirus microbe additive for silkworm is provided.
Another object of the present invention is to provide the preparation method of this antivirus microbe additive for silkworm.
The objective of the invention is to reach by following measure: antivirus microbe additive for silkworm, it is by bacillus licheniformis SHK3, Bacillus licheniformis SHK3, forms through fermentation; Preserving number is CCTCC NO:M206115, and preservation date is on October 31st, 2006.
Bacillus licheniformis SHK3, Bacillus licheniformis SHK3, preserving number are the bacterial classification probation report of CCTCC NO:M206115

Name: Bacillus licheniformis SHK3, bacillus licheniformis SHK3
The difference of the feature of microorganism: bacterium colony is more flat, circular, small circle, light brown appears in neat in edge, wrinkle, coarse, central authorities.
The preparation method of antivirus microbe additive for silkworm, it comprises the steps:
1. bacterial classification is cultivated: bacillus licheniformis SHK3, Bacillus lichenifomisSHK3 bacterial classification are transplanted on the nutrient agar slant medium, are placed 36 ℃ of incubators, cultivated 24 hours, make the bacillus licheniformis rejuvenation;
2. shaking table is cultivated: get in bottles of 500 milliliters conical flasks of above-mentioned slant medium bacterial classification inoculation to 5, adorn 120 milliliters of nutrient broth mediums in every bottle of conical flask, every bottle graft kind 3 rings, moving to shaking table after the inoculation cultivated 18-24 hour, temperature is 36 ℃, be seeded to 50 liters of seed fermentation jars then and cultivate, adorn 35 liters of nutrient solutions in the fermentation tank;
3. 50 liters of seed fermentation jars are cultivated: make defoamer with rape oil or soya-bean oil, with 121 ℃ of sterilization 30min, when waiting to be chilled to 37 ℃, in ventilation than being 0.4-2: 1, rotating speed is 300-500r/min, temperature is under 35-37 ℃ the condition, to ferment 18-24 hour;
4. 1 ton of fermentation tank culture: in adorn 700 liters of nutrient solutions, make defoamer with rape oil or soya-bean oil, with 121 ℃ of sterilization 35min, when waiting to be chilled to 37 ℃, the kind daughter bacteria of cultivating in above-mentioned 50 liters of fermentation tanks is inoculated in 1 ton of fermentation tank, ferment; In ventilation than for 0.4-1: 1, rotating speed is 100-350r/min, temperature is under 35-37 ℃ the condition, fermentation time 36-48 hour; Transfer pH value 3.5-5, be the antivirus microbe additive for silkworm aqua.
In last this technical scheme, the culture medium composition in the described fermentation tank is: yeast extract 0.2%, peptone 1%, glucose 1%, sucrose 1%, calcium chloride 0.2%, sodium hydrogen phosphate 0.1%, potassium dihydrogen phosphate 0.1%, all the other are water.
In last this technical scheme, it also comprises the steps: to add carrier in the microbe additive aqua, again through being mixed into the solid, powdery thing, is antiviral bacteria composition solid pharmaceutical preparation after drying.
In last this technical scheme, described is to be carrier with dry starch, adds dry starch 1.25 weight portions with zymotic fluid 1 weight portion and adds under constantly stirring, and is stirred into graininess, and drying to water content gets final product between 10-12% again.
The present invention is the compositions such as metabolite that utilize antibiotic, antiviral microorganism and secretion thereof, can strengthen silkworm body immunity, stops virus to suck and viral duplicating, thereby reaches antibiotic, antiviral purpose.In addition, the multiple digestive ferment of microorganism secretion is cellulase, hemicellulase, and protease and amylase etc. can promote that silkworm digests and assimilates, and improve the utilization ratio of mulberry leaf, increase the weight of silk cocoon.Simultaneously, microbe additive is the silk improver of pure natural, and is without any side effects to silkworm and people.Therefore, the present invention is that collection is antibiotic, antiviral, enhancing silkworm immunity, improves the silk cocoon quality, is numerous silkworm raisers' increasing both production and income, is a kind of pure natural disease-resistant microorganism additive of silk processing enterprise synergy.
