Rhodopseudomonas acidophila has unique properties among the phototrophic alpha-Proteobacteria and is quite distinct from the type species of Rhodopseudomonas, Rhodopseudomonas palustris. Therefore, the transfer of Rhodopseudomonas acidophila to Rhodoblastus acidophilus gen. nov., comb. nov., is proposed. This proposal is in accordance with other taxonomic reclassifications proposed previously a...

Low-temperature (1.4 K), single-molecule fluorescence-excitation spectra have been recorded for individual reaction center-light-harvesting 1 complexes from Rhodopseudomonas palustris and the PufX(-) strain of Rhodobacter sphaeroides. More than 80% of the complexes from Rb. sphaeroides show only broad absorption bands, whereas nearly all of the complexes from Rps. palustris also have a narrow l...

Forgetting may allow an animal to react more appropriately to current conditions, rather than continuing to exhibit a previously learned, possibly maladaptive behaviour based on previous experience. One theory is that forgetting is an active process, whereby the previously learnt response is replaced by new learning that interferes with the older memory. Hence, we hypothesized that an appropria...

following the occurrence of two large outbreaks in gilan province, northern iran, the public health importance of human fascioliasis has increased significantly. the mixed infections of fasciola gigantica and f. hepatica within a given domestic animal individual suggest a very complicate picture of possible circulation ways of the parasite and the possibility for humans to be infected with both...

In this study, we investigate the interaction of Rhodopseudomonas Palustris (R. Palustris) with montmorillonite clay. The adsorption of bacteria on the clay surface was also determined as a function of the initial bacterial quantity, pH, temperature and ionic strength. At different initial bacterial quantities, the percentage of bacteria adsorbed ranged from 61.07% to 77.57%, and the higher per...

Rhodopseudomonas palustris is a purple, facultatively phototrophic bacterium that uses hydrogen gas as an electron donor for carbon dioxide fixation during photoautotrophic growth or for ammonia synthesis during nitrogen fixation. It also uses hydrogen as an electron supplement to enable the complete assimilation of oxidized carbon compounds, such as malate, into cell material during photoheter...

We examined biofilms formed by the metabolically versatile bacterium Rhodopseudomonas palustris grown via different metabolic modes. R. palustris was grown in flow cell chambers with identical medium conditions either in the presence or absence of light and oxygen. In the absence of oxygen and the presence of light, R. palustris grew and formed biofilms photoheterotrophically, and in the presen...

Partial sequences of farnesyl diphosphate (FPP) synthase genes derived from the Rhodobacter-Rhodovulum group and from the Rhodopseudomonas palustris-Bradyrhizobium japonicum group of the alpha-Proteobacteria were subjected to phylogenetic analysis to investigate the relationships of phototrophic and non-phototrophic bacteria in the alpha-Proteobacteria . The four Rhodovulum species formed a mon...
