The invention relates to the technical field of microorganisms, and discloses a strain of
lactobacillus plantarum HR65, the preservation number of which is CGMCC (China General
Microbiological Culture Collection Center) No.35607. The invention also discloses a preparation method of the
lactobacillus plantarum HR65. The strain can be used for fermenting various
carbohydrate compounds to grow, has obvious effects in the aspects of removing peculiar smell of traditional Chinese medicines and improving

spleen-nourishing
powder can also improve the levels of short-chain fatty acids such as
acetic acid and
butyric acid. The strain has the characteristics of bacteriostasis,
oxidation resistance, production of SOD
enzyme,
cholesterol reduction, self-
agglutination and hydrophobicity, can be widely used for fermenting matrixes such as carrots,
rosa roxburghii tratt, various fruits, Chinese herbal medicines, cereals and milk, improves the
flavor and quality of the matrixes, and has good application value in
plant-based
fermentation products,
traditional Chinese medicine flavor improvement,
