Article Synopsis
- The Mars500 mission involved six crewmembers living in isolation for 520 days to study the human microbiota's composition and its relationship with the host.
- Researchers analyzed 88 salivary microbiota samples over 720 days, focusing on how time, diet, and individual differences influenced microbiota diversity.
- Results indicated that individual variability had the most significant impact on the salivary microbiota, showcasing its personalized nature even in a controlled, shared environment.
During the VIABLE ISS project (eValuatIon And monitoring of microBiofiLms insidE International Space Station), water samples subjected to two different silver treatments were sent and kept on board the International Space Station (ISS) from 2011 to 2016. In this note we report data on the viable and total bacterial load and on the composition of the microbial communities of the VIABLE ISS samples.

- The study focuses on the unique red and black epilithic river biofilms found along the Acquarossa river in Italy, investigating their distinct characteristics and the reasons behind their separation.
- Researchers used various methods to analyze the bacterial communities within these biofilms and discovered that they have very different compositions, with Acinetobacter sp. dominating the black biofilm and iron-oxidizing bacteria in the red one.
- The findings indicate that heavy metal pollution plays a role in the environment and that the competing bacterial populations in these biofilms may influence their structure, showing that biotic interactions affect community formation at a micro level.
Performed inside International Space Station (ISS) from 2011 to 2016, VIABLE (eValuatIon And monitoring of microBiofiLms insidE International Space Station) ISS was a long-lasting experiment aimed at evaluating the bacterial contamination on different surface space materials subjected to different pre-treatment, to provide useful information for future space missions. In this work, surfaces samples of the VIABLE ISS experiment were analyzed to determine both the total bacterial load (ATP-metry, qPCR) and the composition of the microbial communities (16S rRNA genes amplicon sequencing). Data obtained showed a low bacterial contamination of all the surfaces, with values in agreement with those allowed inside ISS, and with a taxonomic composition similar to those found in previous studies (Enterobacteriales, Bacillales, Lactobacillales and Actinomycetales).

Recent studies have shown the dynamic behavior of the gut microbiota in free-living, healthy persons. To date, it is not known whether these dynamics are applicable during prolonged life sharing in a confined and controlled environment.
