Abstract

  The survival of mixed oral bacterial flora in bottled soft drinks by direct drinking during aerobic incubation has been previously reported. Various microaerophilic bacteria are also present in our mouth. The survival of mixed oral bacterial flora in bottled soft drinks by direct drinking during micro aerobic incubation is discussed. The viable cell counts during the microaerobic incubation were greater than those during aerobic incubation when bottled soft drinks were stored at 25°C for 8 hours after direct drinking. Gram negative Diplococcus (Genus Neisseria) were detected after 8 hours. The Genus Bacillus survived during the microaerobic incubation because the spore Genus Bacillus resised the unsuitable condition. The surviving bacterial flora in the bottled soft drinks did not differ between individuals during aerobic incubation.
