An Evaluation of Microorganisms for Unconventional Food Regeneration Schemes in CELSS: Research Recommendations

In addition to research into high productivity green plant agriculture, unconventional food regeneration approaches are being considered as secondary or even primary food sources for Controlled Ecological Life Support Systems. Based on the evidence that microbial food sources can provide all components necessary for human nutrition, attention needs to be given to conducting satisfactory evaluations of microbial food regeneration. Several schemes are presented including past attempts, present research and novel ideas. Proposed research directions and priorities that would permit a proper analysis of the unconventional approach are also indicated.
