Microbial Genomics B11 Strategies to Harness the Metabolic Diversity of Rhodopseudomonas palustris
Rhodopseudomonas palustris is an extremely successful bacterium that can be found in virtually any temperate soil or water sample on earth. It can grow by adopting one of the four major metabolic modes: photoautotrophic growth (energy from light and carbon from C1 compounds), photoheterotrophic growth (energy from light and carbon from organic compounds), chemoheterotrophic growth (carbon and e...
متن کاملMetabolism of methanol by Rhodopseudomonas acidophila.
Rhodopseudomonas acidophila strain 10050, grown anaerobically in the light on methanol, contained a methanol and formaldehyde dehydrogenase which could be coupled to phenazine methosulphate; an NAD-linked formaldehyde dehydrogenase which required GSH for activity; and an NAD-linked formate dehydrogenase. The specific activities of these enzymes varied in a non-coordinate manner when the organis...
متن کاملRegulation of uptake hydrogenase and effects of hydrogen utilization on gene expression in Rhodopseudomonas palustris.
Rhodopseudomonas palustris is a purple, facultatively phototrophic bacterium that uses hydrogen gas as an electron donor for carbon dioxide fixation during photoautotrophic growth or for ammonia synthesis during nitrogen fixation. It also uses hydrogen as an electron supplement to enable the complete assimilation of oxidized carbon compounds, such as malate, into cell material during photoheter...
متن کاملConstruction of a genetically engineered microorganism for CO2 fixation using a Rhodopseudomonas/Escherichia coli shuttle vector.
The CO2 fixation ability of Rhodopseudomonas palustris DH was enhanced by introducing the recombinant plasmid pMG-CBBM containing the form II ribulose-1,5-bisphosphate carboxylase/oxygenase (RubisCO) gene (cbbM) isolated from Rps. palustris NO. 7. Sequencing of a 3.0-kb PstI fragment containing the cbbM gene revealed an open reading frame encoding 461 amino acids, homologous to known cbbM genes...
متن کاملIncreased photoproduction of hydrogen by non-autotrophic mutants of Rhodopseudomonas capsulata.
Non-autotrophic ( Aut -) mutants of Rhodopseudomonas capsulata B10 were tested for their efficiency of nitrogenase-mediated H2 production. Three of these mutants ( IR3 , IR4 and IR5 ) showed an increase stoichiometry of H2 production, mediated by nitrogenase, from certain organic substrates. For example, in a medium containing 7 mM-L-glutamate as nitrogen source, strain IR4 produced 10-20% more...
