Embodiment 1

[0018] Embodiment 1 Bacillus pumilus liquid fermentation

[0019] The bacillus pumilus strain is cultivated in the order of slant, liquid seed, and liquid fermentation, the slant medium is a conventional nutrient agar medium, and the liquid seed medium is a conventional nutrient broth liquid medium; liquid fermentation medium formula (W / V ): Glucose 2%, bean cake powder 8%, corn steep liquor 1%, MgSO 4 ·7H 2 O0.02%, NaCl 0.4%, KH 2 PO 4 0.1%, MnCl 2 0.04%, the fermentation temperature is 30°C, and the ventilation is cultivated for 24-48h. Obtain a high-concentration fermented broth, in which the number of viable bacteria is 10 9 -10 11 cfu / g.

[0020] It is also possible to centrifuge the fermented bacteria liquid to remove the fermented liquid to obtain wet bacteria sludge, add a heat-resistant protective agent, and then spray dry to obtain solid bacterial powder with a viable count of 10 9 -10 11 cfu / g.

Embodiment 2

[0021] Example 2 Solid state fermentation of Bacillus pumilus

[0022] The bacillus pumilus strain is cultivated in the order of slant, liquid seed and solid-state fermentation, the slant medium is conventional nutrient agar medium, and the liquid seed medium is conventional nutrient broth liquid medium. Inoculate the seed culture liquid with 5-10% inoculation amount into the solid-state fermentation medium for solid-state fermentation. The fermentation time is 24-48 hours, the fermentation temperature is 30°C, and the fermentation product is dried and pulverized to obtain the microbial agent of Bacillus pumilus . Among them, the number of live bacteria is 10 9 -10 11 cfu / g.

[0023] Wherein the solid-state fermentation medium is made up of material and water, and described material comprises rice bran 10%, bran 25%, soybean meal 32%, corn flour 30%, yeast extract 2%, NaCl 1 %, the ratio of material to water is 1:1.

Embodiment 3

[0024] The preparation of embodiment 3 mixed preparation

[0025] The described Bacillus pumilus is made into microbial inoculum through solid-state fermentation, and the number of live bacteria of Bacillus pumilus in the described microbial inoculum is 10 9 -10 11 cfu / g, 16 parts of Bacillus pumilus inoculum, 12 parts of vitamin C, 8 parts of Astragalus, 5 parts of Eucommia, 4 parts of Codonopsis, 5 parts of Angelica, 8 parts of honeysuckle, 10 parts of Bupleurum, 5 parts of Ume, 6 parts of pomegranate peel, 10 parts of schisandra. After being pulverized and passed through a 100-mesh sieve, the mixture is uniformly mixed according to the proportion by weight to obtain the mixed preparation.

Abstract

The invention relates to a mixed preparation of bacillus pumilus and an immunopotentiator. The mixed preparation consists of effective components, that is, bacillus pumilus and the immunopotentiator, wherein the bacillus pumilus has a quorum sensing system inhibition function and has the preservation number of CCTCC M 2013240; the immunopotentiator is vitamin C, astragalus membranaceus, eucommia ulmoides, codonopsis pilosula, angelica sinensis, honeysuckle, radix bupleuri, smoked plum, pomegranate bark and schisandra chinensis. The mixed preparation has the advantages that the ability of fish bodies in resisting aeromonas hydrophila infection is remarkably improved, the organism immunity of cultured fishes is improved, the growth of pathogenic entero becteria of fishes is remarkably inhibited, the rapid fish body growth is promoted, and the weight gain rate and the disease resistance of cultured fishes are increased.

Description

technical field [0001] The invention relates to the field of microorganisms, in particular to a mixed preparation of bacillus pumilus and an immune enhancer. Background technique [0002] Bacterial diseases have always been one of the important reasons that plague the development of aquaculture. In recent years, while the high-density and intensive production mode has promoted the increase of production in the aquaculture industry, it has also increased the chance, frequency and harm of bacterial diseases; in addition, drug resistance, drug residues and The destruction of the ecological environment has also become the focus of social attention. Therefore, finding alternative drugs to antibiotics and exploring new control methods have become one of the important research directions for aquatic disease control. [0003] Quorum sensing (QS for short) means that bacteria can spontaneously produce and release some specific signaling molecules, sense changes in their own concent...
