High-temperature-resistant enterococcus faecalis and preparation method thereof

Abstract

The invention relates to high-temperature-resistant enterococcus faecalis and a preparation method thereof. The formula of the high-temperature-resistant enterococcus faecalis consists of the following components in parts by weight of 100-400 parts of coconut oil based sucrose ester active agents, 90-200 parts of camellia oil esters, 60-160 parts of xylooligosaccharide, 50-150 parts of bacillus licheniformis, 80-120 parts of enterococcus faecalis and 40-180 parts of saccharomycetes. The high-temperature-resistant enterococcus faecalis is directly mixed in the processing course of a complete feed, after the high-temperature-resistant enterococcus faecalis and feed components are directly processed at high temperature, a large quantity of viable bacteria are reserved, the decline amplitude in the effective storage period is very small, the high-temperature-resistant enterococcus faecalis resists gastric acid, bile salt and other adverse chemical environments, can be quickly recovered andamplified after entering intestinal tracts of animals and being dissolved under the action of pancreatic fatty acid enzymes and the like, and can be subjected to colonization in the intestinal tracts, and the disease-resistant immunocompetence of the animals is greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a high-temperature-resistant Enterococcus faecalis and a preparation method thereof. Background technique [0002] In response to the rapid development and expansion of the fishery industry and the increasingly serious problems of aquaculture diseases, fishery medicines play an irreplaceable role in my country's aquatic animal breeding and disease control. However, most of the current fishery medicines are imitation veterinary medicines, human medicines and pesticides, etc., which have problems such as lack of science, lack of pertinence, low efficacy, and great impact on the environment, which directly affect the effective prevention and control of aquatic diseases and the production of aquaculture products. quality and safety. Due to the intensification of farming and the disorderly expansion of the scale, the deterioration of the offshore farming environment, and the low ...

Problems solved by technology

At present, such products have entered the Chinese market from abroad, such as the microcapsules of Streptococcus faecalis "Cimeijian" in Switzerland, and "Pfaffia" in the Netherlands, etc., but the price is high and it is difficult to use them on a large scale.

In addition, the use of microecological preparations prepared by microencapsulation technology to produce compound feed for sea fish such as golden pomfret, and the application of this compound for golden pomfret breeding has rarely been reported.
