Hydrogenotrophs, space food, anaerobes.

Hydrogenotrophs are organisms that are capable of metabolizing molecular hydrogen as source of energy and hence hydrogenotrophy is performed by carbon dioxide reducing organism to produce methane. Methanogens are diverse group of strict anaerobes where methanogenesis is a major route in the anaerobic mineralization of organic matter. They have very unique enzyme and cofactors involved in this metabolic pathway. The anaerobic chamber provides a convenient culture system for large-scale studies of strictly anaerobic and/or facultative anaerobic bacteria. In this study, the Hydrogenotrophic organism isolated was characterized as Methanosarcina sp. Though these hydrogenotrophs utilise carbon dioxide and grow in a minimal growth requirement, they were found to be rich in carbohydrates and protein content. Therefore, Hydrogenotroph being a good food source, can be used for future space travel where the astronauts could carry them aboard and synthesis their own food. The by-products produced by these organisms can be used to produce a protein rich meal. This system can be incorporated on to space craft where this works as a closed loop between astronauts and hydrogenotrophs, where carbon dioxide released by astronauts can be captured and filtered through a system and supplied for the growth of these microbes which in turn synthesis carbohydrates.
