Problems solved by technology

In addition, the illegal use of prohibited drugs has seriously exceeded the standard of prohibited drug residues in aquaculture products. For example, the European Union, Eastern Europe, Japan, Hong Kong and other countries and regions have repeatedly returned the livestock products exported by my country. The European Union also stopped importing Chinese feed in August 1996 due to the excessive use of drugs in Chinese feed and excessive residues. Poultry meat and its related products have caused serious economic losses to the country and also damaged the country's image

Embodiment 1

[0041] Example 1 Preparation of Ceramide

[0042] The invention provides a method for preparing ceramide, which is prepared by extracting rice bran as a raw material through bio-fermentation technology, and includes the following steps:

[0043] a. Select strains: select Actinomucor elegans from the General Microorganism Center of China Committee for Microbial Culture Collection: AS3.2778; the amount of strains is 4-12g;

[0044] b. Strain fermentation: carry out solid fermentation of selected strains, and the solid fermentation conditions are:

[0045] Solid medium: rice bran 98.43%, yeast extract 0.7%, KH 2 PO 4 0.1%, K 2 HPO 4 0.1%, MgSO 4 0.05%, CaCl 2 0.05%, ZnSO 4 0.02%, rapeseed oil 0.55%;

[0046] Cultivation temperature: 15℃~35℃;

Embodiment 3

[0115] Embodiment 3 Preparation of by-product enzyme-type feed additive of the method of the present invention

[0116] The remaining product 98.2~99.6% that embodiment 1 separates gained is added following stabilizer: calcium lactate, sorbitol make enzyme type feed additive stabilizer, the consumption scope of calcium lactate 0.2~0.8%, optimum consumption 0.5%; The dosage range is 0.2-1.0%, and the optimal dosage is 0.6%.

[0117] Preparation method: take 98.9 kg of solid fermentation raw materials before fermentation, calculate the respective addition amounts of calcium lactate and sorbitol, and add 10 times the amount of boiling water to dissolve it based on the total amount of 0.5 kg of calcium lactate and 0.6 kg of sorbitol Finally, it is sprayed on the residue after extracting ceramide, stirred evenly, air-dried at 30°C to 50°C, pulverized, packaged, and tested to become the finished product.

[0118] The beneficial effect of the by-product enzyme-type feed additive pre...

Abstract

This invention provides a new usage of actinomucor elegents, especially for the production of ceramide which is prepared by taking tikitiki as the raw material after fermentation, extraction and separation and purification. Another technology is byroduct of such preparation, namely, a zyme type feed additive.

Description

technical field [0001] The invention provides a new application of radiomucor elegans, in particular related to the application of producing ceramide. The invention also provides a preparation method of ceramide, which belongs to the field of biotechnology. Background technique [0002] The strain with the bacterial number AS3.2778 is a typical strain of Actinomucor elegans, which is preserved by the General Microorganism Center of China Committee for the Collection of Microbial Cultures. It is isolated from fermented fermented bean curd and is mainly used in the manufacture of fermented food, especially fermented bean curd. This strain is an excellent strain for brewing fermented bean curd, but other uses of this strain have not been reported yet. [0003] Ceramide can transmit nerve instructions, promote cell proliferation and differentiation, protect the body from external physical (such as ultraviolet rays), chemical (toxic gas), biological and other factors, prevent th...
