Yakult Bacteria Experiment

This experiment solely deals with 65mL Yakult bottles manufactured in Almere, the Netherlands. Mentioning this is of importance, since Yakult bottles are not of the same size in all countries. For example in Taiwan and China Yakult comes in 100mL bottles. Yakult (ヤクルト) is a probiotic yogurt-like beverage made by fermenting a mixture of skimmed milk and sugar with a special strain of the bacteria Lactobacillus casei. Because L. casei Shirota is naturally found in the digestive system, Yakult is touted as beneficial for intestinal health. According to Yakult Honsha Co., Ltd. (株式会社ヤクルト本社) each mL of Yakult contains 100,000,000 bacteria when it is manufactured. This means that each bottle of Yakult contains 6.5 billion bacteria.
