Abstract

Along with the advancement of space science and efforts to extend life beyond the earth, it is important to ‎study the response of microorganisms to microgravity conditions, because the microorganisms will unavoidably ‎be sent to space together with the equipment and passengers. Indeed, exposure to stressful space conditions ‎maybe activates some microorganisms' defense mechanisms which can increase their pathogenicity. Until now, ‎only the responses of a few typical microbes to microgravity have been investigated and the completion of these ‎studies has been delayed due to technical problems and high costs, but it is necessary to study host-microbial ‎interactions, in order to predict these behaviors and take precautionary measures during space flight and even ‎during space station deployment. In the present study, we will review some microbial changes such as growth ‎and metabolic changes and alterations in the expression of genes and proteins under the physical stress of space ‎flight and microgravity simulators.‎
