“…Several studies have shown that biofilms actually grow and accumulate more in space than on Earth. They form faster and therefore become resistant to antibiotics more quickly, and they make thicker structures and have different forms [ 5 , 6 , 7 ]. To date, only a few investigations have been conducted in space to evaluate biofilm formation.…”

“…Microorganisms found in the spacecraft are exposed to unique selective pressures such as microgravity, space radiation, elevated carbon dioxide levels, hypomagnetic conditions, and continuous human habitation [ 4 ]. It has been shown that sometimes these conditions provoke unusual bacterial traits, such as the faster acquirement of antibiotic, chemical, and physical resistance; faster biofilm formation; and altered growth kinetics compared to Earth conditions [ 5 , 6 , 7 ]. The microbiome of the confined spacecraft environment needs to be examined constantly to identify the species of microorganisms that can accumulate in this unique environment, which can change and survive under stress conditions as free-living cells or most importantly as biofilms, and which can influence human health, spacecraft infrastructure, and material integrity.…”

A spacecraft is a confined system that is inhabited by a changing microbial consortium, mostly originating from life-supporting devices, equipment collected in pre-flight conditions, and crewmembers. Continuous monitoring of the spacecraft’s bioburden employing culture-based and molecular methods has shown the prevalence of various taxa, with human skin-associated microorganisms making a substantial contribution to the spacecraft microbiome. Microorganisms in spacecraft can prosper not only in planktonic growth mode but can also form more resilient biofilms that pose a higher risk to crewmembers’ health and the material integrity of the spacecraft’s equipment. Moreover, bacterial biofilms in space conditions are characterized by faster formation and acquisition of resistance to chemical and physical effects than under the same conditions on Earth, making most decontamination methods unsafe. There is currently no reported method available to combat biofilm formation in space effectively and safely. However, antibacterial photodynamic inactivation based on natural photosensitizers, which is reviewed in this work, seems to be a promising method.

“…Bacillus is one of the most dominant genera isolated from MIR (Russian manned spacecraft) (Novikova, 2004) and ISS (Novikova et al ., 2006; Lang et al ., 2017; Checinska Sielaff et al ., 2019). According to the existing data, it is resilient to the harsh cleaning methods (Zhang et al ., 2019) as well as space conditions including gravity-associated stress, radiation (Kacena et al ., 1999; Gabani et al ., 2012; Fajardo-Cavazos et al ., 2014), as well as the acidity (Goswami et al ., 2018).

Corrosion of aluminium (Al) is a potential problem for spacecraft as this metal is used for various mechanical parts due to its strength, durability, etc. However, it can be corroded by certain factors including microbes. Studying microbes which can be implicated in microbiologically influenced corrosion (MIC) due to their extremophilic nature is of vital importance. In this current study, Al and acid-tolerant microbes were isolated from the samples of China space station assembly cleanroom surfaces; acidic environments can accelerate the corrosion process on metal surfaces. Nine bacterial and 10 fungal strains were identified with 16S ribosomal RNA gene/internal transcribed spacer region sequencing and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. The dominant bacteria were of Bacillus, fungi of Penicillium and Aspergillus genera. Knowing the microbes which may be conveyed from the cleanrooms to the space stations with a potential capacity of Al degradation is important for long-term maintenance of station components. This study might aid in designing further researches of the aforementioned microorganisms and, therefore, contribute to the prevention of MIC.
