Rhodospirillum sp. JY3: An innovative tool to mitigate the phytotoxic impact of galaxolide on wheat (Triticum aestivum) and faba bean (Vicia faba) plants [PDF]

Frontiers in Plant Science, 2022
To date, several studies have considered the phytotoxic impact of cosmetics and personal care products on crop plants. Nonetheless, data are scarce about the toxic impact of galaxolide [hexahydro-hexamethyl cyclopentabenzopyran (HHCB)] on the growth ...

Fundamental aspects of sucrose metabolism reveal a trophic link between Rhodospirillum rubrum and Rhodobacter capsulatus [PDF]

mBio
Purple non-sulfur bacteria (PNSB) are well known to have an exceptional metabolic versatility. However, while the growth of PNSB on sugar-rich streams has been extensively explored, their ability to metabolize sugars is poorly understood.

A singular PpaA/AerR-like protein in Rhodospirillum rubrum rules beyond the boundaries of photosynthesis in response to the intracellular redox state [PDF]

mSystems, 2023
Photosynthesis (PS) in purple non-Sulfur bacteria (PNSB) is strictly controlled to avoid energy consumption and to prevent oxidative stress when oxygen is present. PpsR, a transcriptional repressor encoded in the photosynthesis gene cluster (PGC), is one

Gene expression analysis reveals distinct PHB depolymerization mechanisms and broader involvement of the PHB cycle in Rhodospirillum rubrum growing on acetate and fructose [PDF]

Microbial Cell Factories
Background Rhodospirillum rubrum owns a dynamic poly(3-hydroxybutyrate) (PHB) cycle: During growth PHB is accumulated and subsequently degraded under carbon starvation. Interestingly, this cycle is typically found for acetate grown R.

Cryomicroneedle delivery of nanogold-engineered Rhodospirillum rubrum for photochemical transformation and tumor optical biotherapy [PDF]

Bioactive Materials
Tumor metabolite regulation is intricately linked to cancer progression. Because lactate is a characteristic metabolite of the tumor microenvironment (TME), it supports tumor progression and drives immunosuppression.

The metabolic pathways of carbon assimilation and polyhydroxyalkanoate production by Rhodospirillum rubrum in response to different atmospheric fermentation. [PDF]

PLoS ONE
The purple nonsulfur bacteria, Rhodospirillum rubrum, is recognized as a potential strain for PHAs bioindustrial processes since they can assimilate a broad range of carbon sources, such as syngas, to allow reduction of the production costs.
