Description

Lactobacillus pentosus for efficiently degrading phosphorus phytate, fermentation preparation and application thereof
Technical Field
The invention relates to the technical field of microorganisms, in particular to lactobacillus pentosus for efficiently degrading phosphorus phytate, a fermentation preparation and application thereof.
Background
Most of the phosphorus in plant materials is organic phosphorus, accounting for about 85% of the total phosphorus, and exists mainly in the form of nucleic acid, phospholipids and phytate phosphorus. The content of the phytic acid phosphorus in different plant raw materials is greatly different, and especially the content of the phytic acid phosphorus in leguminous plants accounts for 1-5% of dry matters. Since phytate phosphorus affects the effectiveness of other mineral elements, chelate is formed which cannot be digested and absorbed by animals, resulting in reduced utilization of phosphorus by animals. In addition, phytate phosphorus affects the digestion and absorption of other nutrients such as proteins, starches and fats by animals. In order to solve the effect of phytate phosphorus on animal nutrition, the phytase method is generally adopted. Phytase is an enzyme capable of decomposing phytate phosphorus into phytate calcium magnesium salts and other soluble phytate salts. Besides the phytase method, inorganic phosphorus salt is added into the feed to supplement phosphorus source, ensure animal nutrition and improve animal growth performance. These methods are all relatively common and efficient at present, but the addition of phytase and inorganic phosphorus also increases the cost of the feed. In recent years, microbial degradation of phytic acid phosphorus is also a hot spot for research, and the microbial degradation of phytic acid phosphorus is a method for effectively improving the utilization rate of phosphorus in feed mainly through acid production or enzyme production.
