摘要:
A composition containing 1,4-dihydroxy-2-naphthoic acid at a high concentration is obtained by intracellularly and extracellularly producing 1,4-dihydroxy-2-naphthoic acid using a bacterium belonging to the genus Propionibacterium and collecting it. This composition is efficacious in improving intestinal flora, alleviating abdominal ailments in association with the intake of milk, and preventing metabolic bone diseases.

摘要:
Lactobacillus screening methods were carried out using surface plasmon resonance spectrums and human intestinal mucin and blood group antigens as probes. A trial to set selection criteria in the above-mentioned methods of screening for lactobacilli was made to adapt the methods to mass screening, and it was discovered that lactobacilli compatible with ABO blood groups can be screened by setting 100 RU as a criterion for judging bacterial binding under certain conditions. Using 238 lactobacillus strains, the above-mentioned screening methods and tests to judge their compatibility for the use of yogurt production were carried out, to at long last specifically discover bacillus strains compatible with blood groups A, B, and O.

摘要:
A method for stabilizing 1,4-dihydroxy-2-naphthoic acid, which comprises reducing an oxygen dissolved in a solution containing 1,4-dihydroxy-2-naphthoic acid, and food or drink containing 1,4-dihydroxy-2-naphthoic acid.
摘要:
A method for culturing lactic acid bacteria includes (a) adding a proteolytic enzyme to an aqueous whey solution containing whey and water to thereby prepare a culture solution containing whey degraded by the proteolytic enzyme; (b) inoculating the culture solution with Lactobacillus gasseri which is a bacteriocin-producing lactic acid bacteria; and (c) maintaining the culture solution inoculated with the bacteriocin-producing lactic acid bacteria at a pH of not lower than 5.2 and not higher than 5.8 to provide cultured lactic acid bacteria. After the completion of culturing, the culture solution is centrifuged to separate a concentrated cell suspension containing the lactic acid bacterium in a concentrated form. The concentrated cell suspension has extremely high antibacterial activity, several tens of thousands AU, and is usable as a food preservative. Yogurt is produced by fermenting a yogurt mix to which 0.01% to 0.1% by weight of the concentrated cell suspension is added.

摘要:
The survival of lactic acid bacterial strains such as probiotic bacteria contained in yogurt etc. is improved. A lactic acid bacterium survival improver including a propionic acid bacterium fermentation product to improve the survival of a lactic acid bacterium. The propionic acid bacterium is a bacterium belonging to the genus Propionibacterium. The bacterium belonging to the genus Propionibacterium is Propionibacterium freudenreichii.
