Event details
The International Space Station (ISS) represents the most confined man-made and inhabited environment to date. Since October 2000, the ISS has been constantly inhabited by humans. Naturally, the presence of humans also imposes the presence of their associated microorganisms in this confined habitat.
In addition to its confinement, the ISS represents a very unusual microbial biotope. Higher radiation levels than on Earth, low nutrient levels due to reduced introduction of new material, constant temperature (~22°C), stable humidity (~60%) and microgravity characterize the ISS habitat and make it a unique and extreme-situated indoor environment.
The microbiome of the ISS is of special interest for several reasons: for crew's health, but also for the integrity of spacecraft materials. In addition, microorganisms are indispensable for bioregenerative life support systems, such as MELISSA.
In our recent flight project, ARBEX, we analysed the microbial diversity in the different surfaces of the ISS. Numerous samples were taken from the Columbus module, the Cupola, the hygiene area and many other sites. In this talk, I will summarize the current knowledge on the ISS microbiome and present our novel results.
