A polypeptide fragment B (MP-B) has an amino acid sequence shown in SEQ ID NO: 1, in which an amino acid Xaa at position 10 is Arg, Phe, Glu, Thr, or absent, an amino acid Xaa at position 16 is Asn, Val, Leu, Gly, or absent, and an amino acid Xaa at position 25 is Ser, Glu, Met, Arg, or absent. The MP-B can significantly improve the colonic pathologic morphology and decrease a colonic histopathologic score and an expression level of colonic interferon-γ (IFN-γ) in an inflammatory bowel disease (IBD) mouse model, and shows the ability to interfere with the occurrence of IBD in mice.

Provided are a breast milk-derived Lactobacillus plantarum and use thereof. The breast milk-derived Lactobacillus plantarum, which was screened from healthy breast milk, is classified and named as Lactobacillus plantarum and has an accession number of CGMCC NO.19748. It has strong adhesion, has an inhibitory effect on 8 commonly known pathogenic bacteria, and is susceptible to 8 antibiotics, and also has strong acid resistance and bile salt resistance.

A microbial composition for improving the conditions in animal farms comprising: a slow-releasing carrier base having a first predetermined percentage by weight (w/w %); and a mixture of microorganisms identified in a 16S rRNA gene sequence so that the composition is capable of denitrification, feces decomposition, and hydrogen sulfide (H.sub.2S) oxidation.

The present invention relates to Lactobacillus plantarum NK3 and Bifidobacterium longum NK49, which are novel lactic acid bacteria and, more particularly, to a composition comprising novel lactic acid bacteria useful for prevention and treatment of inflammatory diseases.

A method is provided for improving the technological and nutritional properties of gluten-free food matrices based on a fermentation protocol using selected lactic bacteria as starters. The bacteria used are Lactobacillus plantarum strain DSM 33412 and Lactobacillus brevis strain DSM 33413. The method is useful in the processing of gluten-free flowing food material.

Induction mutagenesis in lactic acid bacteria for D(−) lactic acid production from starch was performed and the stable mutant strain of Lactobacillus plantarum improved by the molecular biological technique can be used in production of high optically pure D(−) lactic acid directly from various kinds of starch as a carbon source. Those starch substrates are included cassava starch, corn starch and rice starch, etc. The fermentation product is high optically pure D(−) lactic acid up to 90.0-99.0% which is able to apply in bioplastic and pharmaceutical industries.

The probiotic composition comprises at least one lactic acid bacteria strain, preferably Lactobacillus with intestinal tropism, for use in promoting juvenile growth in livestock, with stimulation of linear growth and/or of IGF-1 level. Exemplary lactic acid bacteria include Lactobacillus plantarum, Lactobacillus fermentum, Lactobacillus casei, Lactobacillus paracasei and Lactobacillus rhamnosus. The strains can be selected in a mouse model. The invention also relates to a probiotic treatment method using this composition.

The present invention relates to the isolated strain of Lactobacillus plantarum VF46A deposited at the CNCM (Collection Nationale De Cultures de Microorganismes, INSTITUT PASTEUR, 25 rue du Docteur Roux, F-75724 PARIS CEDEX15) under the number CNCM 1-5301 on 29 Mar. 2018 as well as to a pharmaceutical composition, a food supplement and a food comprising said strain.

The present invention relates to two new strains of lactic acid bacteria, Lactobacillus brevis DSM 33325 and Lactobacillus plantarum DSM 33326, to a new food composition, and to the process for the preparation thereof.

Stress is any demand placed on the brain or physical body, thereby leading to anxiety and depression and it is a common phenomenon experienced by humans and animals. Stress, anxiety and depression often leads to serious mental ill health. People with anxiety disorders respond to certain things or situations with fear and dread and display physical signs such as a pounding heart and sweating. Often, people lose their willpower, concentration and interest in day to day activities, are drained of energy and can even become devoid of any emotion.

It is documented that low activity of certain neurotransmitters can result in anxiety, chronic stress, depression, difficulty in concentrating, memory problems, muscle pain, headaches, insomnia and sleep problems. Therefore, if the level of these neurotransmitters is raised, the problem of stress, anxiety and depression can be cured. The invention describes a formulation to naturally increase the levels of certain neurotransmitters in the body, thereby reducing stress, anxiety and depression.
