Abstract— The possible nitrogen sources for Osc. trichoides DG6, a typical strain of the Oscillochloridaceae family, are ammonium, N2, glutamate, asparagine, glycine, and glutamine. The assimilation of molecular nitrogen occurs with the participati

The genes encoding carbonic anhydrase (CA) were found in all anoxygenic purple bacteria. The genes of α- and β-CA were found in purple nonsulfur bacteria of the class Alphaproteobacteria:Rhodospirillum rubrum, Rhodospirillum fulvum, Rhodoblastus ac

Dissolved organic matter (DOM) release by anoxygenic phototrophic bacteria belonging to diverse taxonomic groups is a ubiquitous process, resulting in 5–20% of the CO2 fixed by photosynthesis leaving the cell. The green photosynthetic bacterium Chl

The filamentous anoxygenic phototrophic bacterium Oscillochloris trichoides DG-6 has been studied, and it has been shown that there are no lipopolysaccharides on the cell surface. Fatty acids hydroxylated at the C3 position, amino sugars and phosphat

The R and M phase variants of Rhodobacter sphaeroides and Rhodobacter capsulatus were isolated. The growth rates in the dark and in the light in glucose-containing media were much higher for the Rba. sphaeroides R variant than for the M variant. For

The Rand M variants of a purple photosynthetic bacterium Rhodobacter sphaeroides 2R grown on a medium with acetate accumulate poly- β-hydroxybutyrate (PHB). Accumulation of this polymer occurs in the cells grown either anaerobically on the light or

Phaeospirillum fulvum MGU-K5 is an anoxygenic, purple, photoheterotrophic, nonsulfur alphaproteobacterium. Unlike most purple nonsulfur bacteria, MGU-K5 is unable to grow aerobically under chemoorganotrophic conditions. Here, we present the draft gen

Strain BBS, the purple sulfur bacterium assigned initially to the species Thiocapsa roseopersicina, is the best studied representative of this species. However, no molecular phylogenetic analysis has been performed to confirm its systematic position.
