Microbial fermented preparation prepared from procambarus clarkia processing wastes as well as preparation method and application of microbial fermented preparation

Abstract

The invention discloses a microbial fermented preparation prepared from procambarus clarkia processing wastes as well as a preparation method and an application of the microbial fermented preparation.The microbial fermented preparation prepared from the procambarus clarkia processing wastes is prepared from raw materials of procambarus clarkia processing wastes by synergistic fermentation of lactobacillus, bacillus subtilis YS-45 and saccharomyces S-78. The microbial fermented preparation prepared from the procambarus clarkia processing wastes contains rich multiple probiotics and amino acids, has the content of amino acids up to 56.274 mu g/g and has the advantages that the nutrient value is higher, the application range is wider and economic benefits are greater. The preparation methodof the microbial fermented preparation has the advantages that the processing technology is simple, convenient to operate and low in processing cost, can be used for mass preparation and facilitates industrial production. The microbial fermented preparation prepared from procambarus clarkia processing wastes can be widely applied to the feed field as a raw material and has better economic values and application values.

Description

technical field [0001] The invention belongs to the technical field of agriculture and animal husbandry, and relates to a microbial fermentation preparation of crayfish processing waste, a preparation method and application thereof. Background technique [0002] Crayfish, also known as Procambarus clarkii ( Procambarus clarkia ), native to northern Mexico and southern United States, was introduced into my country in the late 1930s and has become one of the most important aquatic economic shrimps in my country. As of 2016, the total output of crayfish in the country was 899,100 tons, with an annual output value of 56.41 billion yuan. In recent years, due to the continuous expansion of the scale of crayfish farming and the continuous increase in output, a large amount of waste of shrimp heads and shrimp shells has been produced in the process of crayfish processing. These processing by-products are rich in nutrients, but most of them are discarded and rarely used. This not o...

Problems solved by technology

[0005] To sum up, there are the following defects in the prior art: (1) The prior art mainly extracts macromolecular proteins and astaxanthin from crayfish processing waste, but does not involve the method of extracting small molecular amino acids; (2) ) There are still the following problems in the existing treatment process: exogenous nutrients need to be added; pH value adjustment, sterilization or heat preservation treatment is required before fermentation; the fermentation conditions required by the microorganisms used are harsh, and the existence of the above problems increases the treatment process and treatment cost, there is a risk of secondary pollution, and it is not conducive to industrial production, which greatly limits the resource reuse of crayfish processing waste
