The strain Lactobacillus casei AH077 (NCIMB12019) produces a polysaccharide and increases energy excretion. The strain acts to block fat absorption and is used in the prevention or treatment of obesity and obesity-related metabolic syndrome.

The present invention is directed to a novel isolated bacterial strain of the Lactobacillus casei (L. casei) species. More in particular, the strain of the Lactobacillus casei species deposited under accession number LMG P-30039. The present invention further relates to the novel L. casei strain for use in the treatment and/or prevention of infections and/or immune-related diseases. Also the use of the isolated novel L. casei strain or a composition comprising said strain as an adjuvant to promote an immune response during vaccination is disclosed. Further, the use of said novel L. casei strain or a composition comprising said strain in personal hygiene industry, cleaning industry, biomass production, air purification and food industry is disclosed. In another aspect of the present invention, the use of a L. casei species that has a whole genome G/C content of at least 47.5% and expresses one or more catalase genes or a composition comprising one or more of said L. casei species in personal hygiene industry, cleaning industry, biomass production, air purification and food industry is disclosed.

The present invention provides a composition for promoting glucolipid metabolism, and a preparation and an application thereof, and relates to the technical field of probiotics. The composition of the present invention includes probiotics and inulin; the probiotics include Bifidobacterium longum, Bifidobacterium breve, Lactobacillus gasseri, Lactobacillus rhamnosus, Lactobacillus salivarius, Lactobacillus cripatus, Lactobacillus plantarum, Lactobacillus fermentum, and Lactobacillus casei. In the composition of the present invention, the nine strains synergize with each other, which function as a regulator of glucolipid metabolism, improve sensitivity to insulin receptor in the body, and relieve insulin resistance when reconstituted with inulin. The composition has some effects on improving serum total cholesterol and triglyceride, islet -cell function, and type 2 diabetes mellitus.

The present invention refers to a composition containing a) a fermented supernatant, or fractions thereof, of Lactobacillus casei or paracasei species, the species being characterized by having in their DNA genome at least one DNA sequence essentially identical to one of the sequence selected from the group consisting of: SEQ ID No 1 to 5, and b) proper carriers and/or diluents and/or excipients. The fermented supernatant is obtainable through a method characterized by the fermentation of the Lactobacillus casei or paracasei species in a minimum solution additioned with prebiotic fibers. The fermented supernatant does not have prebiotic fibers.

Provided is a novel technique for reducing damage and death of microbial cells through a method for producing highly viable dried microbial cells, the method being characterized by subjecting dried microbial cells to an alternating temperature treatment.

A microbial-based composition provides a co-cultured microorganism consortium in culture medium that includes one or more Acetobacter sp., Bacillus sp., Bifidobacterium sp., Enter ococus sp., Gluconacetobacter sp., Lactobacillus sp., Rhodopseudomonas sp., Saccharomyces sp., Pichia sp., and Trichoderma sp., as well as a carbon source and chlorine-free water. In some embodiments, the microbial-based composition is useful in the agricultural industry as a plant growth promoting and silage-enhancing agent. For plant growth promotion applications, the microbial-based composition may be applied to the foliar surface of a plant or to the plant growth medium, such as soil or hydroponic solution, surrounding the plant. In silage operations, the microbial-based composition may be applied to a cut plant product during one or more stages in the silage process.

A method of producing a microbial fermentation broth includes fermenting at least two of plum, dandelion, pine needle, and thistle to prepare each fermentation stock solution, mixing the fermentation stock solutions and fermenting the mixed fermentation stock solutions a to prepare a fermentation mixture, mixing the fermentation mixture with coffee meal and fermenting the mixed fermentation mixture with the coffee meal to prepare a coffee meal fermented solution, and aging the coffee meal fermented solution.

The disclosure provides methods of making a tetracycline inducible expression system in a cell. The methods include providing the cell with a first nucleic acid sequence comprising a first promoter operably linked to a tetracycline repressor gene coding sequence, providing the cell with a second nucleic acid sequence comprising a second promoter operably linked to a coding sequence of a gene of interest wherein the second promoter is modified to include one or more tetracycline repressor protein binding sites, and determining the expression of the gene of interest in the presence or absence of tetracycline. The disclosure further provides nucleic acid sequences, vectors and cells including the tetracycline inducible modified promoter.

The present invention discloses strains of Lactobacillus and Streptococcus which have a capacity to degrade gliadin peptides involved in coeliac disease and which peptide degrading activity is stable under low pH and in the presence of mammalian digestive enzymes. These strains are suitable in a product for use in prevention and/or treatment of celiac disease.

The aim of the present invention is a method for the preparation of anallergic probiotic bacterial cultures.
