Therefore finding a kind of substratum that can improve subtilis antagonistic ability can for promoting that the application of subtilis medicine in biological control corps diseases has great importance.
Summary of the invention
Goal of the invention of the present invention is: for above-mentioned Problems existing, provides a kind of and can promote the application of subtilis in biological control corps diseases, improves the substratum of subtilis antagonistic ability.
The technical solution used in the present invention is as follows:
Bacteria culture medium of the present invention, by 2.0% ~ 4.0% sodium-chlor, 3.7% ~ 5.7% Sodium Propionate, 1.3% ~ 1.9% ammonium acetate, 1.8% ~ 2.4% magnesium sulfate, 1.3% ~ 2.3% calcium chloride, 0.4% ~ 1.4% manganous sulfate, 5.0% ~ 6.2% glutamine, 12.4% ~ 13.6% damping fluid, 15.5% ~ 21.5% peptone, 3.4% ~ 9.4% yeast extract paste, 15.0% ~ 16.8% extractum carnis, 3.6% ~ 5.4% mango extract, 1.3% ~ 2.3% aloe vera gel, 1.8% ~ 2.8% agar, 0.5% ~ 1.1%Gemini tensio-active agent composition and 16.8% ~ 17.4% deionized water composition.
Owing to have employed technique scheme, adopt peptone, extractum carnis and mango extract as the nitrogenous source of microbial culture and carbon source, not only containing benefit materials such as a large amount of carotenoid, vitamins C, pectin and food fibres in mango, simultaneously also containing special Mangiferin, the Mongolian oak flavine of mango acid and similar vitamin b6 usp P mixture, all can promote the growth of bacterium.
The existence of damping fluid ensures that the pH of substratum is in certain constant range, avoids bacterium in process of growth, and the generation of meta-bolites changes the pH environment of substratum, makes pH change excessive and the growth of anti-bacteria.
Sodium-chlor, Sodium Propionate, ammonium acetate, magnesium sulfate, calcium chloride and manganous sulfate provide composition as necessity trace element of bacterial growth, lacking trace element manganese, calcium, magnesium etc. can cause bacterial growth slow, if but the too high levels of inorganic salt, indissoluble thing can be formed in the medium, on the contrary can the growth of anti-bacteria, therefore, aforementioned proportion is the most rational scope.
Bacteria culture medium of the present invention, by 3.0% sodium-chlor, 4.7% Sodium Propionate, 1.6% ammonium acetate, 2.1% magnesium sulfate, 1.8% calcium chloride, 0.9% manganous sulfate, 5.6% glutamine, 13.0% damping fluid, 18.5% peptone, 6.4% yeast extract paste, 15.9% extractum carnis, 4.5% mango extract, 1.8% aloe vera gel, 2.3% agar, 0.8%Gemini tensio-active agent composition and 17.1% deionized water composition.
Owing to have employed technique scheme, aforementioned proportion is optimum value.
Bacteria culture medium of the present invention, described peptone is spirulina protein peptone.
Owing to have employed technique scheme, prior art adopts Japanese peptone to carry out culturing bacterium usually, price costly, cost is higher, in the group thing of spirulina wherein more than 60% be protein, mainly comprise Isoleucine, leucine, Methionin, methionine(Met), phenylalanine, Threonine, tryptophane and α-amino-isovaleric acid, in addition, also fatty, carbohydrate, chlorophyll, carotenoid, phycocyanin, vitamin A, B1, B2, B6, B12, E, nicotinic acid, creatine, gamma-linolenic acid, calcium pantothenate, folic acid (folicacid) and calcium, iron, zinc, magnesium etc.Can the quality protein peptone of separation and Extraction makes new advances from spirulina cheapness, the spirulina protein peptone of being made up of spirulina can provide required nitrogenous source and carbon source for bacterial growth.
Bacteria culture medium of the present invention, the structural formula of described Gemini surface active is as follows,
Owing to have employed technique scheme, this tensio-active agent can stimulate the generation of bacterium antagonistic substance, and improves the output of antagonistic substance.
Bacteria culture medium of the present invention, described mango extract is prepared by following steps,
Starch dissolution, by mango: the mass ratio 12:1 of starch, is clean mango in the water of 25 ~ 38 DEG C in temperature by step one: take fresh mango;
Step 2: mango cleaned in step one being immersed in concentration is in the salt solution of 4.82mol/L, is 550W at microwave power, temperature is pre-treatment 20min under the condition of 27 DEG C;
Step 3: mango treated in step 2 is taken out, uses normal temperature clean water;
Step 4: the mango dried in step 3 is immersed in dehydrated alcohol, mango: the mass ratio of dehydrated alcohol is 1:1.5, is 400W at microwave power, temperature is pre-treatment 20min under the condition of 30 DEG C;
Step 5: in dehydrated alcohol, fragmentation is carried out to the mango through step 4 process, add water by dehydrated alcohol dilution be 73% ethanolic soln, at pressure 0.62kPa, reflux under the condition that temperature is 78 DEG C 5h;
Step 6: by the reaction system filtered while hot in step 5, obtain filtrate one and filter residue one, get filter residue one and be dissolved in ethyl acetate, filter residue: the mass ratio of ethyl acetate is 1:1.5, reflux 5h under the condition of temperature 78 DEG C;
Step 7: by the reaction system filtered while hot in step 6, obtains filtrate two and filter residue two;
Step 8: get filtrate one obtained in step 6, by the ethanol removing in system, being cooled to normal temperature, being placed in 360nm, under the high voltage mercury lamp of 2kW, is 96mW/cm in light intensity
2, irradiation distance is irradiation 2h under the condition of 8cm, and system surface forms one deck membranoid substance, discards membranoid substance, obtains suspension liquid;
Step 9: mixed with filtrate in step 7 two by the suspension liquid in step 8, removes aqueous solvent and ethyl acetate, obtains mango extract.
Owing to have employed technique scheme, in the effect of microwave, cell walls in vegetable cell can be destroyed rapidly and improve molecular motion speed, such that the natural product that contains in mango is more enough to be penetrated faster and better from vegetable cell, improve the output of efficiency and the extract extracted.Containing a kind of special material---mango laccol in mango, this material is unfavorable for the growth of bacterium, and laccol is water insoluble, and is oily matter, and the density of laccol is less than the density of water; Laccol has the physical properties of film forming, and high pressure pumping lamp can send strong UV-light, and under strong UV-irradiation, laccol can rapid film formation, utilizes this characteristic can either get rid of laccol in extract efficiently.
