Attempts were made to culture Spirulina platensis in human urine directly to achieve biomass production and O(2) 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 approximately 240. Accumulation of lipid and decreasing of protein occurred due to N deficiency. O(2) release rate of Spirulina platensis in diluted human urine was higher than that in Zarrouk medium.
人们尝试直接在人类尿液中培养钝顶螺旋藻,以实现生物量生产和氧气释放,从而有可能应用于生命支持系统中的养分再生和空气 revitalization(此处原文可能有误,推测为“空气再生”)。培养结果表明,钝顶螺旋藻在稀释的人类尿液中生长成功,并且在尿液稀释比例为 140 至 240 时产生最大生物量。由于氮缺乏,脂质积累且蛋白质含量降低。钝顶螺旋藻在稀释的人类尿液中的氧气释放速率高于在 Zarrouk 培养基中的释放速率。
