Embodiment 1

[0024] First weigh 3 parts of phosphate, 15 parts of glucose, and 1 part of nitrogen beef extract powder to make fermentation auxiliary materials.

[0025] Then weigh 2 parts of Bacillus licheniformis, 3 parts of Bacillus subtilis and 1 part of the above-mentioned fermentation auxiliary material, mix evenly, place in a fermenter, and ferment at 30°C for 5 days to obtain a microbial preparation. The number of live bacteria of the bacteria preparation obtained by detection was Bacillus licheniformis 10 8 Individual / g, Bacillus subtilis 10 5 pcs / g.

[0026] Both the Bacillus subtilis and the Bacillus licheniformis were purchased from China Industrial Microorganism Culture Collection Management Center, specifically Bacillus subtilis CICC 10090 and Bacillus licheniformis CICC20205.

Embodiment 2

[0028] First weigh 1 part of phosphate, 20 parts of glucose, and 2 parts of nitrogen beef extract powder to make fermentation auxiliary materials.

[0029] Then weigh 2 parts of Bacillus licheniformis, 8 parts of Bacillus subtilis and 1 part of the above-mentioned fermentation auxiliary material, mix them evenly, place them in a fermenter, and ferment at 30° C. for 5 days to obtain a microbial preparation. The number of viable bacteria in the detected bacterial preparation was Bacillus subtilis 10 9 Individual / g, Bacillus licheniformis 10 6 pcs / g.

Embodiment 3

[0031] First weigh 2 parts of phosphate, 25 parts of glucose, and 1 part of nitrogen beef extract powder to make fermentation auxiliary materials.

[0032] Then weigh 2 parts of Bacillus licheniformis, 6 parts of Bacillus subtilis and 1 part of the above-mentioned fermentation auxiliary material, mix evenly, place in a fermenter, and ferment at 30° C. for 5 days to obtain a bacterial preparation. The number of viable bacteria in the detected bacterial preparation was Bacillus subtilis 10 8 Individual / g, Bacillus licheniformis 10 5 pcs / g.

Abstract

The invention relates to a microecological preparation used for improving penaeus vannemei immunity. The preparation comprises bacillus subtilis, bnfillus licheniformis, and fermentation auxiliary materials. The components are composed according to a weight ratio of 3-8:2:1, such that the microbial preparation is prepared. The microbial preparation provided by the invention contains two high-quality effective bacteria. The strains are strictly selected and cultivated according to microecological regularities. The high quality of the strains is ensured, and viable bacteria content is high. The shelf life of the preparation reaches 24 months. The microbial preparation has good microecosystem regulating and immunity enhancing functions, and especially has substantial function in improving penaeus vannemei immunity.

Description

technical field [0001] The invention belongs to the field of aquatic feed, in particular to a microbial preparation for improving the immunity of Penaeus penaeus and southern shrimps. Background technique [0002] In recent years, the scale of intensive culture of Penaeus penaeus and southern white shrimp has been expanding day by day. The increase of culture density and the deterioration of the culture environment often cause the stress response of the shrimp body, resulting in the decline of the shrimp body and the increase of diseases, which have caused serious losses to the aquaculture industry. With the in-depth study of microbiology and microecology, the use of microecological preparations to regulate the microecological balance in animals, restore the normal physiological functions of the body, prevent and control diseases, and improve health. The research and application of microecological preparations has attracted more and more people. Much attention. Contents of...
