Provided is a Lactiplantibacillusplantarum TCI837, deposited in the Leibniz Institute DSMZ under an accession number of DSM 33843. Based on this, the Lactiplantibacillusplantarum TCI837 can be used to prepare a composition for supplementing iron and/or promoting the absorption of iron in a subject, and to prepare a composition for improving the gut microbiota in a subject. In addition, the composition may be an iron supplement composition containing the Lactiplantibacillusplantarum TC1837 and an iron supplement.

The present invention relates to a novel Lactobacillus plantarum IMB19 strain, polysaccharides derived from the strain, and a use thereof. A novel Lactobacillus plantarum IMB19 strain and polysaccharides derived from the strain of the present invention exhibit an excellent CD8+T cell activity stimulating ability and Treg cell inhibitory activity, and stimulate and improve an antitumor immune response through various mechanisms such as increased macrophage infiltration in CPS tumors and differentiation and reprogramming of macrophages into an inflammatory phenotype (M1). Therefore, a strain and polysaccharides derived from the strain of the present invention can be effectively used for immune regulation, especially immune boosting, in a subject, and can inhibit tumor growth by inducing and enhancing an antitumor immune response. A novel strain and polysaccharides derived from the strain of the present invention are useful in the prevention, alleviation or treatment of such as tumors, infectious diseases and various immune diseases that are the cause of or symptom of immune dysfunction.

A composition having Lactobacillus Plantarum strain GMNL-662 for promoting bone regrowth is provided. The Lactobacillus Plantarum strain GMNL-662 has an ability to promote the expression of osteogenic genes, inhibit the expression of osteoclast related genes, and promote the expression of osteogenesis-related cytokine TGF-β, so that the bone loss is improved.

Microorganisms for lowering blood ammonia level and composition for protecting neuronal cells containing the same, particularly relates to microbes or a symbiotic pair that has a neuroprotective function by lowering blood ammonia levels or reducing ammonia levels in the body and composition for protecting neuronal cells comprising the microbes. The microorganisms having a neuroprotective function by lowering the blood ammonia level can be selected from the group that include, but not limited to, a Lactobacillus sp. strain and a Streptococcus sp. strain. The ammonia removal strains and the composition have a neuroprotective effect by their excellent ability to remove neurotoxic ammonia, and thus can be widely used as a preventive or therapeutic agent for hyperammonemia and neurological diseases caused thereby.

The present invention relates to a method of extracting a low-molecular-weight proanthocyanidin using cranberries and lactic acid bacteria, and more particularly, the method may include (S1) growing and extracting a seed culture from cranberries, (S2) reinforcing the metabolism of a saccharide by adjusting a metabolic process, (S3) extracting the seed culture whose metabolic process is adjusted and culturing the extracted result, (S4) mixing cranberries, distilled water and a saccharide with the grown seed culture and fermenting the mixture, and (S5) extracting an unbound polyphenol from the fermented mixture.

A polypeptide fragment C (MP-C) has an amino acid sequence shown in SEQ ID NO: 1, in which an amino acid Xaa at position 9 is Tyr, Val, Gly, Ser, or Gln, an amino acid Xaa at position 20 is Ser, Gln, Glu, or Tyr, an amino acid Xaa at position 30 is Asn, Thr, Ser, Pro, or Leu, and an amino acid Xaa at position 42 is Gly, Arg, Met, or absent. The MP-C can significantly improve the colonic pathologic morphology and decrease a disease activity index (DAI) and a colonic histopathologic score in an inflammatory bowel disease (IBD) mouse model, and shows the ability to interfere with the occurrence of IBD in mice.

The disclosure provides novel microbial strains, such as Veillonella sp. strains, and compositions comprising the strains that are capable of converting lactate to propionate and acetate. The disclosure also provides compositions comprising the Veillonella sp. strains and lactate producing bacteria, such as Lactobacillus sp. strains and Bifidobacterium sp. strains. The disclosure further provides methods of improving athletic performance, enhancing exercise endurance and reducing inflammation in a subject upon administration of the disclosed strains or compositions.

The present invention relates to a food composition for enhancing respiratory function and improving respiratory diseases, using Lactobacillus plantarum KF511 strain; a health functional food comprising the food composition; and a pharmaceutical composition for preventing or treating the respiratory diseases, comprising Lactobacillus plantarum strain, its culture solution, its concentrate, or its dried product, as an active ingredient.

The Lactobacillus plantarum KF511 strain, according to the present invention shows activities of inhibiting secretion of MUC5AC in a mucus hypersecretion model using a respiratory epithelial cell (H292) of a human, inhibiting Netosis activation of neutrophil extracellular traps, inhibiting expression of inflammatory cytokines by Cigarette Smoke Extraction (CSE) of NCI-H292 cells that are a bronchial epithelial cell line, and furthermore, inhibiting damage of a lung tissue in a mouse model of a respiratory disease induced by the CSE and PPE, inhibiting infiltration of immune cells such as total cells, macrophages, lymphocytes, eosinophils, and neutrophils in BALF, and inhibiting secretion of inflammatory cytokines and chemokines in the BALF and the lung tissue.

The present invention relates to a novel Lactobacillus plantarum IMB19 strain, polysaccharides derived from the strain, and a use thereof. A novel Lactobacillus plantarum IMB19 strain and polysaccharides derived from the strain of the present invention exhibit an excellent CD8+T cell activity stimulating ability and Treg cell inhibitory activity, and stimulate and improve an antitumor immune response through various mechanisms such as increased macrophage infiltration in CPS tumors and differentiation and reprogramming of macrophages into an inflammatory phenotype (M1). Therefore, a strain and polysaccharides derived from the strain of the present invention can be effectively used for immune regulation, especially immune boosting, in a subject, and can inhibit tumor growth by inducing and enhancing an antitumor immune response. A novel strain and polysaccharides derived from the strain of the present invention are useful in the prevention, alleviation or treatment of such as tumors, infectious diseases and various immune diseases that are the cause of or symptom of immune dysfunction.

The disclosure relates to a Lactobacillus plantarum HG-23 and application thereof. The Lactobacillus plantarum HG-23 has been deposited with the China Center for Type Culture Collection as assigned Accession Number CCTCC No.: M2021330. The Lactobacillus plantarum HG-23 of the disclosure can be used for preparing hypolipidemic food or hypolipidemic drugs. The Lactobacillus plantarum HG-23 screened in the disclosure is good in safety, can tolerate gastric acid and bile salts, and survives and colonizes in intestinal tract to regulate and improve the intestinal microecological balance of a host, so as to play a beneficial effect and generate an exact healthy effect; in-vitro and animal tests show that the Lactobacillus plantarum HG-23 has a strong function of reducing triglyceride and cholesterol in blood.
