recommendations! Published in 2017 at "Biotechnology and Bioengineering"

DOI: 10.1002/bit.26076

Abstract: The photosynthetic bacterium Rhodobacter capsulatus normally photoproduces H2 as a by‐product of its nitrogenase‐catalyzed nitrogen‐fixing activity. Such H2 production, however, is expensive from a metabolic perspective, requiring nearly four times as many photons as the… read more here.

recommendations! Published in 2019 at "MicrobiologyOpen"

DOI: 10.1002/mbo3.921

Abstract: Rhodobacter capsulatus fixes atmospheric nitrogen (N2) by a molybdenum (Mo)‐nitrogenase and a Mo‐free iron (Fe)‐nitrogenase, whose production is induced or repressed by Mo, respectively. At low nanomolar Mo concentrations, both isoenzymes are synthesized and contribute… read more here.

DOI: 10.1016/j.bioelechem.2020.107456

Abstract: Cells of the facultative photosynthetic bacterium Rhodobacter capsulatus exploit the simultaneous presence in the cultural medium of the toxic oxyanion tellurite (TeO32-) and the redox mediator lawsone (2-hydroxy-1,4-naphthoquinone) by reducing tellurite to metal Te0 nanoprecipitates… read more here.

DOI: 10.1016/j.ijhydene.2018.09.038

Abstract: Abstract Photofermentative hydrogen production from synthetic mixtures of lactose and lactate mimicking cheese whey was modeled and optimized using Design of Experiments and Response Surface Methodology. Five continuous parameters (light intensity, pH, lactose, lactate and… read more here.

DOI: 10.1016/j.jhazmat.2016.11.002

Abstract: The toxic oxyanion tellurite (TeO32-) is acquired by cells of Rhodobacter capsulatus grown anaerobically in the light, via acetate permease ActP2 and then reduced to Te0 in the cytoplasm as needle-like black precipitates. Interestingly, photosynthetic… read more here.

DOI: 10.1021/acs.biochem.0c00821

Abstract: PYPs (photoactive yellow proteins) are blue light sensor proteins found in more than 100 species. Compared with the extensive and intensive studies of the reactions of PYP from Halorhodospira halophila (Hh-PYP), studies of the reactions… read more here.

recommendations! Published in 2022 at "Microbiology Spectrum"

DOI: 10.1128/spectrum.02354-22

Abstract: The CRP/FNR family of regulatory proteins constitutes a large collection of related transcription factors, several of which globally regulate cellular energy production. A well-characterized example is FNR (called FnrL in Rhodobacter capsulatus), which is responsible… read more here.

DOI: 10.3389/fmicb.2019.00301

Abstract: This paper describes a mutant (called SB1707) of the Rhodobacter capsulatus wild type strain SB1003 in which a transposon-disrupted rcc01707 gene resulted in a ∼25-fold increase in the accumulation of coproporphyrin III in the medium… read more here.
