Abstract

The present invention relates to a Kefiranofaciens subsp.kefiranofaciens ZW3 strain which is obtained from the Kefir grains through filtering separation and is preserved in Laboratory of culture collection of the Microbiology, Chinese Academy of Science. The preservation data is December 18, 2008, and the preserving number is CGMCC2809. The ZW3 strain of the invention has the advantages of excellent thermal stability, strong emulsifying capacity and high yield of exopolysaccharide. The exopolysaccharide which is obtained by separating and purifying the fermentation broth of the ZW3 strain is the macromolecule biological polysaccharides. The exopolysaccharide not only can be used as the thickening agent and the emulsifier in the food industry, but also can be used as the probiotics for promoting the growth of other probiotics in the intestional canal. The exopolysaccharide is also related with the functions of anti-tumor, anti-fistula, immunoregulation, cholesterol lowering or blood pressure regulating of the probiotics. Furthermore the exopolysaccharide has biodegradability and has no harm to the human body and the environment. The exopolysaccharide can be used as an effective flocculant in the food fields of wastewater treatment, drinking water product, downstream processing, etc.

Description

technical field

[0001] The invention belongs to the field of bioengineering and relates to a strain of Lactobacillus kumi subspecies ZW3. Background technique

[0002] In recent years, the food industry has increasingly strong demand for natural polymers, which has also aroused people's interest in exopolysaccharides produced by microorganisms. Many microorganisms, including lactic acid bacteria, algae, fungi, and plants, have the ability to synthesize exopolysaccharides and secrete them as soluble or insoluble polymers. Microbial exopolysaccharides are widely used in food, pharmaceutical and chemical fields, as bioflocculants, biosorbents, heavy metal removers, drug release agents, etc. Industrially important microbial exopolysaccharides are dextran, xanthan, gellan, pullulan, yeast glucan and bacterial alginate. Microbial exopolysaccharides have been developed into food additives like Xanthomonas produced by Xanthomonas and Kelp produced by Pseudomonas Elodea. However, ...
