Biomass-supported catalysts on Desulfovibrio desulfuricans and Rhodobacter sphaeroides [PDF]

, 2008
A Rhodobacter sphaeroides-supported dried, ground palladium catalyst (‘‘Rs-Pd(0)’’) was compared with a Desulfovibrio desulfuricans-supported catalyst (‘‘Dd-Pd(0)’’)and with unsupported palladium metal particles made by reduction under H2 (‘‘Chem-Pd(0)’’)

Quantitative Resistance to Quinone Outside Inhibitor (QoI) Fungicides in Puccinia horiana Through the Combination of Seven Distinct Substitutions in Cytochrome b

Plant Pathology, Volume 75, Issue 1, January/February 2026.
Puccinia horiana, the causal agent of chrysanthemum white rust, has developed quantitative resistance to QoI fungicides through one to four substitutions, selected from F90I, N256S, Y257N, L275F, F278L, M295V or L299F in cytochrome b (Cytb). ABSTRACT Quinone outside inhibitors (QoIs) are a major class of agricultural fungicides.

Cardiolipin increases in chromatophores isolated from Rhodobacter sphaeroides after osmotic stress: structural and functional roles

Journal of Lipid Research, 2009
Chromatophores isolated from cells of Rhodobacter sphaeroides exposed to hypertonic solutions were enriched in cardiolipin (CL). Because CL levels are raised by increasing the incubation time of R.

Optical signatures of quantum delocalization over extended domains in photosynthetic membranes

, 2015
The prospect of coherent dynamics and excitonic delocalization across several light-harvesting structures in photosynthetic membranes is of considerable interest, but challenging to explore experimentally.

The C-terminus of PufX plays a key role in dimerisation and assembly of the reaction center light-harvesting 1 complex from Rhodobacter sphaeroides. [PDF]

, 2017
In bacterial photosynthesis reaction center-light-harvesting 1 (RC-LH1) complexes trap absorbed solar energy by generating a charge separated state. Subsequent electron and proton transfers form a quinol, destined to diffuse to the cytochrome bc1 complex.

Effect of Roseovarius litoreus Supplementation on Growth Performance, Antioxidant Capacity, and Gut Bacterial Community of Pacific White Shrimp (Litopenaeus vannamei)

Aquaculture Research, Volume 2026, Issue 1, 2026.
Rhodobacteraceae strains are known to play multiple beneficial roles in shrimp aquaculture. Roseovarius litoreus (RL), a member of this family, has demonstrated probiotic effects in crabs. To explore its potential role in shrimp, this study evaluated the effects of RL on the growth performance, antioxidation, and gut bacterial community of the ...

Precise regulating the specific oxygen consumption rate to strengthen the CoQ10 biosynthesis by Rhodobater sphaeroides

Bioresources and Bioprocessing
Coenzyme Q10 (CoQ10) is the most consumed dietary supplement and mainly biosynthesized by aerobic fermentation of Rhodobacter sphaeroides (R. sphaeroides). Oxygen supply was identified as a bottleneck for improving CoQ10 yield in R. sphaeroides.

Absence of the cbb3 terminal oxidase reveals an active oxygen-dependent cyclase involved in bacteriochlorophyll biosynthesis in Rhodobacter sphaeroides. [PDF]

, 2016
The characteristic green color associated with chlorophyll pigments results from the formation of an isocyclic fifth ring on the tetrapyrrole macrocyle during the biosynthesis of these important molecules.

Exploring lipid diversity and minimalism to define membrane requirements for synthetic cells

FEBS Letters, Volume 599, Issue 24, Page 3569-3590, December 2025.
Designing the lipid membrane of synthetic cells is a complex task, in which its various roles (among them solute transport, membrane protein support, and self‐replication) should all be integrated. In this review, we report the latest top‐down and bottom‐up advances and discuss compatibility and complexity issues of current engineering approaches ...
