| 摘 要： | INTRODUCTION For long distance manned space missions, bio- logical life support systems (BLSS) have to be in- troduced into the life support system to achieve regeneration of nutrient matter (Volker and Frank, 2001). Recently, many kinds of subsystems within BLSS have been proposed and experimented on solely or jointly, which include mainly higher plant, aquatic organisms (Volker and Frank, 2001), micro- organisms and microalgae (Gros et al., 2003). Mi- croalgae were incorporated in …

| Abstract: | Attempts were made to culture Spirulina platensis in human urine directly to achieve biomass production and O2 evolution, for potential application to nutrient regeneration and air revitalization in life support system. The culture results showed that Spirulina platensis grows successfully in diluted human urine, and yields maximal biomass at urine dilution ratios of 140~240. Accumulation of lipid and decreasing of protein occurred due to N deficiency. O2 release rate of Spirulina platensis in diluted human urine was higher than that in Zarrouk medium. |
