Without some form of regenerative life support system, long duration space habitation or travel will be limited severely by the prohibitive costs of resupplying air, water, and food from Earth. Components under consideration for inclusion in a regenerative life support system are based on either physicochemical or biological processes. Physicochemical systems would use filtration and elemental phase changes to convert waste materials into usable products, while biological systems would use higher plants and bioreactors to supply crew needs. Neither a purely biological nor strictly a physicochemical approach can supply all crew needs, thus, the best each approach can offer will be combined into a hybrid regenerative life support system. Researchers at Kennedy Space Center (KSC) Advanced Life Support Breadboard Project have taken the lead on bioregenerative aspects of space life support. The major focus has been on utilization of higher plants for production of food, oxygen, and clean water. However, a key to any regenerative life support system is recycling and recovery of resources (wastes). In keeping with the emphasis at KSC on bioregenerative systems and with the focus on plants, this paper focuses on research with biologically-based options for resource recovery from inedible crop residues.

概述:从作物残留物中回收营养以用于空间应用

如果没有某种形式的再生生命支持系统,长时间的太空居住或旅行将受到从地球重新供应空气、水和食物的高昂成本的严重限制。考虑纳入再生生命支持系统的组件基于物理化学或生物过程。物理化学系统将使用过滤和元素相变将废料转化为可用产品,而生物系统将使用高等植物和生物反应器来满足船员的需求。纯粹的生物方法或严格的物理化学方法都不能满足所有船员的需求,因此,每种方法所能提供的最好的方法都将结合到混合再生生命支持系统中。肯尼迪航天中心 (KSC) 高级生命支持面包板项目的研究人员在太空生命支持的生物再生方面处于领先地位。主要的重点是利用高等植物来生产食物、氧气和清洁水。然而,任何再生生命支持系统的关键是资源(废物)的回收和回收。与 KSC 对生物再生系统的重视和对植物的关注相一致,本文重点研究基于生物学的选择,以从不可食用的作物残留物中回收资源。
