一些浮游植物可以作为建立受控生态生命支持系统(CELSS)的可能候选者，因为它们的一些内在特征，首先是它们应该生长迅速，其次它们应该能够承受一些压力因素并制定相应的适应策略，而且它们能够为船员提供丰富的营养蛋白质和维生素，最后但并非最不重要的是它们还可以完成CELSS的其他主要功能，包括供应氧气、清除二氧化碳和回收代谢废物。根据这些特点，中国潜在的保健食品发菜被选为CELSS的潜在生产者。结果表明，该藻的平均放氧速率约为150mmolO-2 mg(-1)h(-1)，大小为2~20 mm。此外，它还可以进行高密度的培养，这表明发菜在有限的体积内具有比其他藻类更高的潜在生产力。我们测量了蓝藻的营养含量，得出结论：它是船员的好食物。基于上述优势，发菜被认为是一种适合建立受控生态生命支持系统的浮游植物。我们计划开发合适的蓝藻生物反应器，在未来的太空任务中提供氧气和食物。皇冠版权(C)2011，由爱思唯尔有限公司代表空间研委会出版。版权所有。
Some phytoplankton can be regarded as possible candidates in the establishment of Controlled Ecological Life Support System (CELSS) for some intrinsic characteristics, the first characteristic is that they should grow rapidly, secondly, they should be able to endure some stress factors and develop some corresponding adaptive strategies; also it is very important that they could provide food rich in nutritious protein and vitamins for the crew; the last but not the least is they can also fulfill the other main functions of CELSS, including supplying oxygen, removing carbon dioxide and recycling the metabolic waste. According to these characteristics, Nostoc sphaeroides, a potential healthy food in China, was selected as the potential producer in CELSS. It was found that the oxygen average evolution rate of this algae is about 150 mu mol O-2 mg(-1) h(-1), and the size of them are ranged from 2 to 20 mm. Also it can be cultured with high population density, which indicated that the potential productivity of Nostoc sphaeroides is higher than other algae in limited volume. We measured the nutrient contents of the cyanobacterium and concluded it was a good food for the crew. Based on above advantages, Nostoc sphaeroides was assumed to a suitable phytoplankton for the establishment of Controlled Ecological Life Support System. We plan to develop suitable bioreactor with the cyanobacterium for supplying oxygen and food in future space missions. Crown copyright (C) 2011 Published by Elsevier Ltd. on behalf of COSPAR.
