Abstract:
Objective To summarize the latest studies on the biological effects of microgravity or simulated microgravity on microorganisms in the world. Literature resource and selection The related published articles and reviews in the field. Literature quotation Thirty-eight references were cited. Literature synthesis Studies showed that microgravity environment of space could induce the variations of microorganisms on their physiological, biochemical and genetic characteristics.Some microorganism populations, those are originally unharmful to human body or environment, show variations on virulence, pathogenicity, sensitivity to antibiotics, etc. Conclusion Studies on the effects of microgravity on microorganisms have important theoretical and practical significance on clarifying the survival and mutation mechanism of microorganisms in microgravity, establishing the future's space controlled ecological life support system, monitoring the safety of microorganisms in the space and rationally utilizing microgravity resources.
