Pediococcus acidilactici micro-capsule and preparation method thereof

Abstract

The invention provides a pediococcus acidilacticimicro-capsule and a preparation method thereof, and relates to the field of non-antibiotic feed additives and preparation methods thereof. The pediococcus acidilacticimicro-capsule is a 40-60-micrometer micro-capsule prepared by conducting microencapsulation on a seed solution of pediococcus acidilactici through sodium alginate and polyethylene glycol, then high-density liquid fermentation culture is conducted in a fermentation tank, and finally a preparation is obtained through spray drying. According to the pediococcus acidilacticimicro-capsule, pediococcus acidilactici can grow and multiply in quantity in the capsule wall, the capsulewall of the micro-capsule has reticulated pores, mass transfer is not affected, medium components can freely enter and exit, the treatment process is simple, the production is continuous, and the pediococcus acidilactici is better protected, the thallus is resistant to high temperature, the activity of the thallus is effectively kept, it can be guaranteed that fermentation metabolites are not lost, the wastewater discharge is reduced, the product cost is further lowered, and the thallus activity is kept at90% or above. The products of the company are more competitive in the market.

Description

technical field [0001] The invention relates to the field of non-antibiotic feed additives and a preparation method thereof, in particular to a Pediococcus lactis microcapsule and a preparation method thereof. Background technique [0002] There are more than 100 known species of lactic acid bacteria. The application history of lactic acid bacteria is very long, such as the production and production of dairy products, pickles, silage, etc. There are a large number of lactic acid bacteria in the intestines of humans and animals. Lactic acid bacteria preparation is a preparation containing live lactic acid bacteria called Lactobacillus. Lactic acid bacteria grow and develop in the intestinal tract, decompose sugars to generate lactic acid and form an acidic environment, thereby inhibiting the proliferation of harmful bacteria in the intestinal tract, and preventing toxin production and disease-causing. The strains for preparing the lactic acid bacteria preparation include L...

Problems solved by technology

However, because Pediococcus lactis has high requirements on nutritional status and nutritional conditions, and the final concentration of growth bacteria is not high

In addition, Pediococcus lactis is not resistant to high temperature and is dried by freeze-drying. The product has high activity but requires high cost and equipment investment.

Spray drying and fluidized bed drying methods require less investment in equipment, but it is easy to cause bacterial death and loss of activity. Fluidized bed drying technology requires post-processing techniques such as centrifugation to separate the solid and liquid of the bacterial cells in the fermentation broth, which not only makes the fermentation broth The metabolites in the water are lost in vain, and cause waste water discharge
