“…For long-duration space missions, advanced life support (ALS) systems will be needed to produce food, recycle air and water, and decompose waste [1]. ALS components, including those using microbes, must function reliably [2]. Stability of processes is often included in the concept of component or system reliability because a stable system is less likely to be changed by external variables [2,3].…”

“…ALS components, including those using microbes, must function reliably [2]. Stability of processes is often included in the concept of component or system reliability because a stable system is less likely to be changed by external variables [2,3]. Stable biological systems maintain a steady-state equilibrium from which there is little deviation [2][3][4].…”

“…Stability of processes is often included in the concept of component or system reliability because a stable system is less likely to be changed by external variables [2,3]. Stable biological systems maintain a steady-state equilibrium from which there is little deviation [2][3][4]. Another aspect of system reliability commonly encountered in biological systems is resilience -the ability of an ecological system or community to recover from perturbations [3].…”

“…For microbial communities incorporated into ALS components, the most important aspect of reliability is being able to maintain the activities necessary for proper function of that ALS component, whether that function is bioconversion of inedible plant residue to CO 2 , recovery of trace nutrients, or decomposition of other wastes [2,5]. Strayer et al [2] have confirmed that CO 2 evolution and total microbial biomass can be reliably maintained for periods of more than a year. Examination of the internal stability of a microbial community as it degrades heterogeneous substrates in inedible plant residue is among the next steps in determining how to control and maintain biological components for ALS, especially since decreases in biological diversity have been observed in microbial communities after closure in bioreactors and mesocosms [6,7].…”
