Abstract

Biofilms are collections of bacteria that commonly grow on a variety of surfaces. They are resistant to environmental impacts as bacteria fortify themselves to a surface. Biofilms are commonly found on Earth, but more problematically are also found on spacecraft. On the ISS biofilms have developed in spaces like the workout area, food spaces, and most concerning in the Water Recovery System (WRS). Biofilms tend to react differently to attempted cleaning methods in space than they do on Earth and can be located in extremely difficult to reach places.   This study aims to explore the effects of gamma radiation on biofilm formation in comparative samples with and without microgravity simulation. It also aims to investigate how the combination of multiple bacterial species into one biofilm effects these results. This study will be conducted through growing biofilms with just one species or multiple, under either normal or microgravity environments, with or without gamma radiation present.   Understanding the effect of gamma radiation and microgravity on biofilms allows us to better keep astronauts safe from virulent bacteria growth in space and ensures clean, safe spacecraft.

Effects of Microgravity and Gamma Radiation on Biofilm Growth
