The invention discloses
lactobacillus delbrueckii with a
muscle protection function in a fat reducing period as well as a product and application thereof, belongs to the technical field of microorganisms, and discloses
lactobacillus delbrueckii subsp. Lactis Turb8 with the preservation number of CGMCC No.35627. The
lactobacillus delbrueckii subsp. Lactis Turb8 has the advantages that the preservation number is CGMCC No.35627; the strain or the preparation thereof can effectively prevent or improve the accompanying problems of
muscle loss and function decline in the process of applying fat-reducing drugs such as GLP-1
receptor agonists (such as
liraglutide and semeglutide), and the effect of reducing fat but not reducing
muscle is achieved. The strain disclosed by the invention can be used for remarkably increasing the
lean body mass ratio of a user, increasing the
muscle mass of lower limbs, increasing the cross sectional area of muscle fibers and improving muscle function indexes such as strength of four limbs and suspension endurance while keeping the original weight-reducing effect of a fat-reducing
medicine. The invention also relates to microbial agents comprising this strain, various preparations, their use in the preparation of products for ameliorating (in particular
drug-induced) muscle reduction.
