Rubrivivax benzoatilyticus sp.nov., an aromatic hydrocarbon-degrading purple betaproteobacterium [PDF]

, 2006
A brown-coloured bacterium was isolated from photoheterotrophic (benzoate) enrichments of flooded paddy soil from Andhra Pradesh, India. On the basis of 16S rRNA gene sequence analysis, strain JA2(T) was shown to belong to the class Betaproteobacteria ...

[Bacteriochlorophyll a synthesis in Rhodopseudomonas palustris].

Revista Argentina de microbiologia, 1983
By means of electron microscope it was demonstrated that photosynthetically-grown Rhodopseudomonas palustris exhibits an intracytoplasmic membrane system (Figure 1a), which is not observed in aerobically-dark grown bacteria (Figure 1b). The content of bacteriochlorophyll alpha and the enzyme activity of succinil-CoA-synthetase, ALA-sinthetase and ALA ...

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.

Bioprocess modelling of biohydrogen production by Rhodopseudomonas palustris: Model development and effects of operating conditions on hydrogen yield and glycerol conversion efficiency [PDF]

, 2015
This research explores the photofermentation of glycerol to hydrogen by Rhodopseudomonas palus- tris, with the objective to maximise hydrogen production. Two piecewise models are designed to simulate the entire growth phase of R.

PFAS properties and destruction methods: A focus on enzymatic degradation

Journal of Chemical Technology &Biotechnology, EarlyView.
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 ...

tRNA signatures reveal polyphyletic origins of streamlined SAR11 genomes among the alphaproteobacteria [PDF]

, 2013
Phylogenomic analyses are subject to bias from compositional convergence and noise from horizontal gene transfer (HGT). Compositional convergence is a likely cause of controversy regarding phylogeny of the SAR11 group of Alphaproteobacteria that have ...

Substrate specificity of citrate lyase deacetylase of Rhodopseudomonas gelatinosa and Rhodopseudomonas palustris [PDF]

Journal of Bacteriology, 1981
Citrate lyase (EC 4.1.3.6) isolated from Rhodopseudomonas palustris was investigated with regard to its kinetic properties and its subunit composition. This enzyme was inactivated by citrate lyase deacetylase (EC 3.1.2.-) of Rhodopseudomonas gelatinosa. A corresponding cross-reaction was measured with partially purified deacetylase of 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.

Cobalt(II) bioaccumulation and distribution in Rhodopseudomonas palustris

Biotechnology & Biotechnological Equipment, 2017
Bioaccumulation by growing cells is a potential technique for the removal of heavy metals from wastewater. Cobalt bioaccumulation by Rhodopseudomonas palustris via different metabolic pathways was investigated for various pH levels, temperatures, co ...
