【摘要】 螺旋藻是一种有希望成为载人航天提供气体交换和食品来源的藻类。我们利用返地式卫星的8天航天飞行条件,研究微重力等航天因素对飞行后螺旋藻生长发育的影响。结果表明,航天后的螺旋藻形态、生长和发育与地面对照没有显著差异,但航天螺旋藻的指数生长期的生长率快于地面对照(p<0.05)。更多还原

【Abstract】 With the advent of space flight, there is renewed interest in the use of algae to regenerate oxygen , absorb carbon dioxide and treat wastes in a future biological life-support system. Spirulina is a potential algae originator to provide food and air revitalization for manned space missions. The influence of space-flight factors, especially weightlessness on the growth of spirulina flown for 8 days in a recoverable satellite was studied by postflight cultivation. The morphology, growth and development of spirulina in space was not significantly different from those of the ground-based controls, but the growth rate of logistic growth period of spirulina in the satellite was faster than that on the ground (p <0.05).更多还原
