A method for increasing gastric tract acid (GTA) production in a mammalian subject. The method comprises administering a therapeutically-effective amount of a composition comprising at least one liveor attenuated culture of a microbial species selected from the genus Blautia, species Faecalibacterium prausnitzii, genus Bacteroides, family Ruminococcaceae, family Lachnospiraceae, genus Coprococcus, genus Roseburia, genus Oscillospira, species Ruminococcus bromii, genus Ruminococcus, family Costridiaceae, species Dorea formicigenerans, species Bacteroides uniformis, genus Dorea, genus Streptococcus, order Clostridiales, genus Anaerostipes, genus Dialister, species Bifidobacterium adolescentis, family Coriobacteriaceae, genus Faecalibacterium, genus Sutterella, species Bacteroides ovatus, genus Parabacteroides, genus Ruminococcus, species Bacteroides faecis, species Eubacterium biforme, genus Phascolartobacterium, and family Enterobacteriaceae; or a prebiotic composition which increasesgrowth and / or viability of said microbial species in the gut. Administering the composition increases the synthesis of at least one GTA dicarboxylic fatty acid metabolite in said subject. Also described are method for determining gastrointestinal inflammation status and kits for detecting and treating a gastric tract acid (GTA) insufficiency.

The invention provides a streptococcus, which is a new species in the genus Streptococcus, named: Streptococcus sp.64, which is registered and preserved in the Guangdong Provincial Microorganism Culture Collection Center, and the preservation number is GDMCC No: 61194. The Streptococcus sp.64 of the present invention can produce strong antibacterial active substances after being fermented and cultured, and has obvious antibacterial effect on Pseudomonas aeruginosa and Burkholderia melioidosis, etc. The prevention and treatment of diseases caused by Pseudomonas and Burkholderia melioidosis has a broad development space, and has a good development and application prospect in the aspect of antibacterial drugs.

The invention provides a streptococcus, which is a new species in the genus Streptococcus, named: Streptococcus sp.121, registered and preserved in Guangdong Microbial Culture Collection Center, and the preservation number is GDMCC No: 61195. The streptococcus Streptococcus sp.121 of the present invention can produce stronger antibacterial active substance after fermenting and cultivating, and all have more obvious antibacterial action to Klebsiella pneumoniae and Shigella dysenteriae etc. It has a broad development space in the prevention and treatment of diseases caused by bacillus and Shigella dysenteriae, and has a good development and application prospect in antibacterial drugs.

Provided are an oil-in-water emulsion, and in particular a foaming oil-in-water emulsion, having sufficient milk flavor and body taste while using a minimal amount of milk product such as fresh cream, butter, whole powdered milk, or nonfat dry milk. Additionally, provided are an oil-in-water emulsion, and in particular a foaming oil-in-water emulsion which has a more abundant milk flavor and body taste when the same amount of milk product such as fresh cream, butter, whole powdered milk, or nonfat dry milk is used. This oil-in-water emulsion uses a specific lactic acid fermentation emulsion which contains fat and oil, nonfat milk solid, and water, and for which the amount of oil and fat is 4.5-35.0 wt% and the amount of milk protein is 2.5-11.0 wt%, wherein the lactic acid bacterium used by the lactic acid fermentation emulsion is a combination of the streptococcus family and the lactobacillus family, the amount of oil and fat is 15-50 wt%, and the amount of nonfat milk solid is 0.5-12.0 wt%.

The invention discloses recombinant Streptococcus zooepidemicus for fermentation of micromolecule hyaluronic acid and belongs to the technical field of bioengineering. Hyaluronidase derived from leeches is heterologously expressed in Streptococcus zooepidemicus, nine kinds of signal peptides are selected and are fused with the terminal N of the hyaluronidase, and an appropriate signal peptide is selected through comparison of enzyme activity through a Pspac-induced promoter and Streptococcus RBS so that efficient secretion and expression of hyaluronidase in Streptococcus zooepidemicus is realized. Through degradation of macromolecule hyaluronic acid produced by the Streptococcus zooepidemicus, active micromolecule hyaluronic acid is obtained and a yield is improved. The recombinant Streptococcus zooepidemicus lays a foundation for the efficient fermentation preparation of micromolecule hyaluronic acid based on a microbial system and is suitable for industrial production and application.

The invention is based on a method for the detection of Streptococcus pneumoniae in a sample, which allows a specific distinction between Streptococcus pneumoniae and other species of the Streptococcus genus. Furthermore, the present invention relates to (i) a kit comprising a microarray in which the probes of the present invention are disposed; (ii) the probe set itself; (iii) a microarray comprising the probe set; and (iv) the above Methods, kits, probe sets, and uses of microarrays for the detection of Streptococcus pneumoniae in a sample.

The invention discloses a gene chip of aquatic product cultivation pathogenic bacterium, comprising a solid phase carrier which is modified chemically, a detection probe and a quality control probe are distributed on the solid phase carrier in a dot matrix way; the detection probe comprises specificity 16S rDNA sequences and / or gyrB gene sequences of vibrio, comma bacillus, vibrio harveyi, vibrio alginolyicus, vibrio anguillarum, vibrio parahemolyticus, nocardia, nacardia seriolea, aeromonas, hydrophilic aeromonas, streptococcus and dolphin streptococcus, which are to be detected, the quality control probe includes PCR positive, chip fixed positive control, chip hybridizing negative control, chip hybridizing positive control and chip hybridizing blank control; the gene chip has the advantages of small volume and high flux, can detect known and unknown germs of the vibrio, the nocardia, the aeromonas and the streptococcus, and can detect specific germs with multiple kinds, and the simpleness and rapidness and specificity of the germs can be detected, and automatic detection can be carried out after detection software is additionally arranged.

The invention provides a streptococcus, which is a new species in the genus Streptococcus, named: Streptococcus sp.76, registered and preserved in Guangdong Microbial Culture Collection Center, and the preservation number is GDMCC No: 60774. The streptococcus Streptococcus sp.76 of the present invention can produce stronger bacteriostasis active substance after fermenting and cultivating, and all have more obvious bacteriostasis to Staphylococcus aureus and Salmonella typhi etc. There is a broad space for development in the prevention and treatment of diseases caused by Salmonella, and it has a good development and application prospect in the aspect of antibacterial drugs.
