Unique Adaptations of a Photosynthetic Microbe Rhodopseudomonas palustris to the Toxicological Effects of Perfluorooctanoic Acid

bioRxiv
In this study, we investigate the PFOA removal capabilities of Rhodopseudomonas palustris (R. palustris), a fluoroacetate dehalogenase containing microbe as a potential candidate for achieving bioremediation.

Reduction of selenite to red elemental selenium by Rhodopseudomonas palustris strain N.

PLoS ONE, 2014
The trace metal selenium is in demand for health supplements to human and animal nutrition. We studied the reduction of selenite (SeO₃⁻²) to red elemental selenium by Rhodopseudomonas palustris strain N.

Phototrophic Fe(II) oxidation by Rhodopseudomonas palustris TIE-1 in organic and Fe(II)-rich conditions.

Environmental Microbiology
Rhodopseudomonas palustris TIE-1 grows photoautotrophically with Fe(II) as an electron donor and photoheterotrophically with a variety of organic substrates. However, it is unclear whether R.

The oxygen‐sensing FixLJ represses nitrogen fixation in Rhodopseudomonas palustris in response to oxygen

mLife, EarlyView.
Abstract Biological nitrogen fixation in symbiotic diazotrophs is subject to oxygen regulation by an oxygen‐sensing FixLJ two‐component system under micro‐oxic conditions. However, it remains unclear whether this mechanism is conserved in free‐living diazotrophs.

ATP Is a Major Determinant of Phototrophic Bacterial Longevity in Growth Arrest

mBio, 2023
How bacteria transition into growth arrest as part of stationary phase has been well-studied, but our knowledge of features that help cells to stay alive in the following days and weeks is incomplete.

Polyesterase activity and thermostability of carboxylesterases from Thermoleophilum album YS‐3

The FEBS Journal, EarlyView.
Three novel α/β‐hydrolases from thermophilic bacterium Thermoleophilum album display carboxylesterase and polyesterase activity. These enzymes hydrolyse PET, PLA and PCL both at high and moderate temperatures. TA21 shows superior activity, efficiently converting MHET to terephthalic acid. Structural features underlying substrate binding highlight their

PFAS properties and destruction methods: A focus on enzymatic degradation

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 6, Page 1126-1152, June 2026.
Abstract Per‐ and polyfluoroalkyl substances (PFAS) are known as ‘forever’ chemicals and have lasting detrimental impact on the environment and living organisms. To understand PFAS molecules better, this review begins with an overview of PFAS definition, classifications and applications, and then provides a comprehensive summary and critical analysis ...
