Photoheterotrophic Assimilation of Valerate and Associated Polyhydroxyalkanoate Production by Rhodospirillum rubrum.

ABSTRACT: Purple nonsulfur bacteria are increasingly recognized for industrial applications in bioplastics, pigment, and biomass production. In order to optimize the yield of future biotechnological processes, the assimilation of different carbon sources by Rhodospirillum rubrum has to be understood. As they are released from several fermentation processes, volatile fatty acids (VFAs) represent a promising carbon source in the development of circular industrial applications. To obtain an exhaustive characterization of the photoheterotrophic metabolism of R. rubrum in the presence of valerate, we combined phenotypic, proteomic, and genomic approaches. We obtained evidence that valerate is cleaved into acetyl coenzyme A (acetyl-CoA) and propionyl-CoA and depends on the presence of bicarb
