Decrease of Effects of Mutagenic Factors on a Human Body Under Conditions of a Long-Term Space Flight

The paper presents the results of experiments conducted in order to develop a simplified technology for producing fermented milk probiotic foods aboard a manned space complex (MSC). Since a variety of mutagenic factors attacks the human body during a long-term space flight, one can assume that at some moment the compensatory abilities of the human immune system will be completely exhausted. The developed technology was shown to be a single-stage operation (“Just add water” technology) and requires neither additional equipment nor special knowledge in microbiology for its implementation. The technology was successfully tested aboard the ISS. The samples of fermented milk foods obtained by the crews of the ISS-50 and 52 have a high probiotic potential, so the said technology can be recommended for producing the treatment-prophylactic product during long-term space missions.
