Characterization Of Rhodopseudomonas Palustrus Strains For The Production Of Fixed Nitrogen Fertilizer For Mars, Daniel Kade Derrick
Characterization Of Rhodopseudomonas Palustrus Strains For The Production Of Fixed Nitrogen Fertilizer For Mars, Daniel Kade Derrick
Undergraduate Honors Capstone Projects
The purpose of this project was to characterize the potential of various strains of purple non-sulfur bacteria for the production of fixed nitrogen fertilizers for the manned Mars missions. Six strains of Rhodopseudomonas palustris (CGA009, CGA010, TIE-1, NifA*, and PB23) were all investigated. Through initial growth trial experiments, R. palustris NifA* and PB23 were selected for their engineered nitrogen fixation and rapid growth respectively. Growth curves and ammonium concentrations were collected over time in pilot scale batch photobioreactors (200 mL). Biomass production was then scaled up to benchtop photobioreactors (1.5 L) and then 14 L total volume for both NifA* …
