Charge Recombination Kinetics of Bacterial Photosynthetic Reaction Centres Reconstituted in Liposomes: Deterministic Versus Stochastic Approach

Data, 2020
In this theoretical work, we analyse the kinetics of charge recombination reaction after a light excitation of the Reaction Centres extracted from the photosynthetic bacterium Rhodobacter sphaeroides and reconstituted in small unilamellar phospholipid ...

Controls on brGDGT Production in the Seasonally Anoxic Water Column and Sediments of Rotsee (Lake Rot)

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract Reliable paleotemperature proxies are essential for reconstructing past climate. To refine interpretation of the MBT'5ME index, based on bacterial brGDGT lipids, a year‐long study was conducted in Rotsee, Switzerland, a seasonally stratified lake with a 4–21°C temperature range.

Photosynthetic apparatus of Rhodobacter sphaeroides exhibits prolonged charge storage

Nature Communications, 2019
Photosynthetic proteins are used to harvest solar energy in bio-photovoltaics, but are typically not investigated for charge storage. Here the authors report prolonged charge storage in multilayers of photoproteins as well as a proof-of-principle ...

An Extract of Rhodobacter sphaeroides Reduces Cisplatin-Induced Nephrotoxicity in Mice

Toxins, 2013
Cisplatin is used as a treatment for various types of solid tumors. Renal injury severely limits the use of cisplatin. Renal cell apoptosis, oxidative stress, and inflammation contribute to cisplatin-induced nephrotoxicity.

Gas‐Phase Integration of Trophically Distinct Microbial Cultures for Net‐Reduced CO2 and Enhanced Metabolite Production

Microbial Biotechnology, Volume 18, Issue 12, December 2025.
A gas‐linked co‐culture system that enables spatially separated yet metabolically connected microbial interactions has been found to enhance the sustainable production of value‐added metabolites while eliminating CO2 emissions. ABSTRACT The continued increase in atmospheric CO2 concentrations has intensified global efforts to develop sustainable ...

The bacterial RNA polymerase-associated CarD protein couples promoter activity to DNA supercoiling

Nature Communications
RNA polymerase (RNAP) must unwind duplex DNA prior to transcription initiation. In bacteria, unwinding starts at a DNA motif called the promoter −10 element. Specifically, non-template strand bases interact with RNAP to trigger the process.

Energy conversion in Purple Bacteria Photosynthesis [PDF]

, 2011
The study of how photosynthetic organisms convert light offers insight not only into nature's evolutionary process, but may also give clues as to how best to design and manipulate artificial photosynthetic systems -- and also how far we can drive natural
