It is perhaps no surprise that most built environment-associated bacteria behave very similarly on the ISS as on earth. After all, the ISS is a home and office of sorts, with environmental conditions very similar to a building on earth with the exception of gravity. The ISS is maintained at around 22 °C with a relative humidity of around 60%. Additionally, this experiment didn't provide enough time to study the long-term adaptation of bacteria to the environment on board the ISS.  A related project from our lab has examined the microbial community already present on the ISS (Lang et al 2015). submitted).  Given that the ISS appears to harbor similar microbes to built environments on earth, we also asked if there were close relatives to our 48 bacteria already present on the ISS. The vast majority (39/48) of our bacterial species were found in the existing microbial community data which is not surprising given the built environment origins of the isolates. This suggests that our data showing these species growing with similar kinetics on space and on earth is potentially relevant to the biology of the microbial communities already present on the ISS.
