  • Patent number: 8986675
    Abstract: The present invention relates to the prevention and treatment of obesity and obesity related metabolic syndrome, particularly to the prevention and treatment of obesity by changing intestinal flora. The characteristics of intestinal bacteria are transformed by administration of a microorganism preparation which improves free fatty acid absorption by the bacteria, and free fatty acid absorption in the gastrointestinal tract is thereby decreased by introduction thereof. The present invention provides a method for preventing and treating obesity and obesity related metabolic syndrome, a pharmaceutical composition and diet supplement for prevention and treatment thereof, and modified probiotic strains usable for such purposes. The present invention provides a weight loss effect and shows that the absorption of fatty acids in the gastrointestinal tract is blocked by improving the characteristics of intestinal bacteria and transplanting them, thereby enabling the treatment of obesity.

  • Patent number: 8722035
    Abstract: Disclosed are formulations for enhancing the in vivo colonization of probiotic microorganisms that include digestive enzymes and probiotic microorganisms, and polysorbate surfactants. The enzymes include lactogenic enzyme formulations that promote growth of Lactobacillus probiotics, bifidogenic enzyme formulations that promote growth of Bifidobacterium probiotics and combination formulations that benefit both types of probiotics. It has been discovered that certain polysorbate surfactants, including polysorbate-60 and polysorbate-80, further promote probiotic microorganism growth, when used with the enzyme formulations. The formulations are preferably compounded as dry powders, to avoid water reaction with the enzymes in blended formulations. Such formulations can be contained in capsules, tablets, packets or bottles and administered orally, either sequentially or in one combined formulation.

  • Patent number: 5466463
    Abstract: A vaginal suppository or other type of vaginal pessary such as cream, foam or ointment, which contains as its active ingredients at least one pharmaceutically acceptable, topically safe antimicrobial agent, such as an agent selected from the group of benzalkonium chloride, cetylpyridinium chloride, chlorhexidine gluconate and povidone iodine, imidiazolidinyl urea and diazolidinyl urea and a viable colony of micro-encapsulated lactobacilli bacteria. The viable lactobacilli are included in the suppository in micro encapsulated form, which protects the bacteria during storage of the suppository from the action of the bacteriocidal agent. When exposed to the vaginal milieu the micro encapsulation breaks down sufficiently to release the lactobacili bacteria. The lactobacilli bacteria serve to maintain or re-establish a healthy lactobacilli based flora on the vaginal wall, and excrete hydrogen peroxide and other bactericidins which suppress abnormal flora conditions that promote infections.

  • Patent number: 5459053
    Abstract: A novel process for producing lactic acid using the rumen contents collected from slaughtered cattle or sheep is disclosed. The rumen contents are initially incubated for a period of time and under sufficiently low pH conditions effective to kill and/or inactivate non-lactic acid producing bacteria therein. Prior to or following this inactivation, the rumen contents are combined with a supplemental culture medium to form a fermentation broth and provide additional sources of carbohydrate and organic N for enhanced growth of lactic acid bacteria. In the second stage of the process, the fermentation broth is fermented under conditions promoting growth of the lactic acid bacteria to increase their cell mass to high densities. Optimal growth is attained by adjusting the pH of the fermentation broth to between about 6.6 to 7.2 and then incubating under anaerobic conditions for a sufficient time to lower its pH to between about 4.7 and 5.2.

    Abstract: 2-Oxo-4-phenylbutyric acid is treated with a microorganism, which has been optionally treated, capable of asymmetrically reducing 2-oxo-4-phenylbutyric acid into either (R)-2-hydroxy-4-phenylbutyric acid or (S)-2-hydroxy-4-phenylbutyric acid, and the (R)-2-hydroxy-4-phenylbutyric acid or (S)-2-hydroxy-4-phenylbutyric acid thus produced is recovered to thereby give optically active 2-hydroxy-4-phenylbutyric acid.The optically active 2-hydroxy-4-phenylbutyric acid is an important intermediate in the synthesis of various drugs such as a remedy for hypertension.

  • Patent number: 5204247
    Abstract: A new strain Lactobacillus sp. KPB-176, which does not possess strict selectivity for specific media and which involves no reduction in the productivity of polysaccharides even during subculture, was isolated from kefir grains. When this new strain is cultured on a medium containing milk whey and casamino acid or when on a medium containing carbohydrate and yeast extract, capsular polysaccharides are produced in high yields.

  • Patent number: 4910024
    Abstract: A method and apparatus for preparing at a livestock feedlot a concentrated suspension of anaerobic bacteria at a known, accurate concentration and for storing the prepared suspension for prolonged periods at the feedlot in a ready-to-use condition without significant loss of viability, allowing feedlot operators to conveniently administer such bacterial supplements to large numbers of livestock as a probiotic on a regular basis in accurate dosages. The apparatus comprises an insulated liquid-holding vessel cooled by a refrigeration means, and mixing and recirculation means to ensure temperature and concentration homogeneity of the bacterial suspension. The vessel and contents are gravimetrically monitored to ensure accuracy of bacterial concentration.
