| 摘 要： | 随着航天事业的迅猛发展，太空感染问题亟待深入研究。微生物是存在于自然界的一群体形微小、结构简单的微小生物。随宇航员和太空飞行器进入太空的微生物，在失重环境下生长变化，时刻威胁着宇航员的健康及飞行器的安全。本文主要对模拟微重力及太空飞行环境中微生物的生物学特性变化，包括微生物形态结构、生长速率、细胞代谢、毒力、生存能力和基因表达等方面做一综述，以期进一步对微重力及太空飞行环境下微生物属性变化进行研究。

| Abstract: | With the great development of aerospace enterprise, space infection is a new subject to be investigated. Attaching to astronauts and spacecrafts, microorganisms may go into outer space and grow under microgravity environment and then threaten the health of astronauts and the safety of aircrafts. This paper summarizes the biological characteristic changes of microorganisms in simulated microgravity and spaceflight environment, including the aspects of the microbial morphology, growth rate, cellular metabolism, virulence, viability and gene expression, and aims to further investigate biological effects of simulated microgravity and spaceflight on microorganisms. |
