As it became known “MK”, the new treatment-and-prophylactic drink will be produced from probiotic bifidobacteria and lactobacilli, whose positive effect on health, about a hundred years ago proved a famous scientist Mechnikov. In particular, using the drinks based on probiotics, a person normalizes intestinal microflora, which in turn strengthens the immune system. In microgravity, where the human body experiences the maximum load, it becomes most relevant.

Become the first producers of lactic acid drink in space was lucky enough to cosmonauts Sergei Ryzhikova and Andrey Borisenko, who will travel to the ISS in September aboard the “Soyuz MS-02”. In laying for the experiment will be the container, the container semi-product of lactic acid bacteria and bifidus bacteria, nutrient medium, and a thermostat to maintain the desired temperature. Method of cooking space “yogurt”: the capacity of microbiological billet astronauts pour drinking water from an onboard source, mix it all method “intense shaking” and on the day placed in an incubator with a constant temperature of 37 degrees Celsius.

Alas, after the preparation of fermented milk beverage the astronauts will not be able to try it on the ISS. Under strict instructions, ready to “kefir” called “Probiotic” will be defined in a cooling chamber before returning to Earth.

We plan to use this drink as a regular probiotic in the implementation of long-duration missions to Mars and the moon.
