Not only on Earth, but also on the International Space Station ISS, protection against germs plays a major role. Once introduced by astronauts, the conditions for bacteria and other germs are even better in space: they can mutate more easily and thus develop resistance. In addition, conventional disinfectants may not be used on the ISS due to the risk of explosion and medical care is limited. To investigate how bacteria spread on the ISS, researchers have tested various coatings on the toilet door, including the new agent AGXX. The result: after six months, no germs have survived on the surface coated with AGXX, unlike on the other two surfaces – untreated steel and steel coated with silver. The AGXX coating prevents microorganisms from attaching themselves to the surface and contaminating it. The use of such antimicrobial solutions is therefore a promising weapon against the spread of germs.
