Aerobic chemolithoautotrophic growth and RubisCO function in Rhodobacter capsulatus and a spontaneous gain of function mutant of Rhodobacter sphaeroides.

Abstract excerpt

Photosynthetic prokaryotes that assimilate CO2 under anoxic conditions may also grow chemolithoautotrophically with O2 as the electron acceptor. Among the nonsulfur purple bacteria, two species (Rhodobacter capsulatus and Rhodopseudomonas acidophilus), exhibit aerobic chemolithoautotrophic growth with hydrogen as the electron donor. Although wild-type strains of Rhodobacter sphaeroides grow poorly, if at all,...
