A new purple bacterium (strain T4), capable of heterotrophic aerobic and phototrophic anaerobic growth, was isolated from waste water of a noodle factory near Hanoi, Vietnam. A comparison of 16S rDNA sequences revealed its association with the genus Rhodocista. The isolate, tentatively named “Rhodocista hanoiensis”, forms cysts after growth on butyratecontaining plates at 42 °C. The vegetative cells form short (under aerobic conditions) or long curve-shaped rods. In contrast to other species of this genus T4 does not need any supplines (growth factors, not synthesized by the organisms). Comparative studies of T4 with Rhodocista centenaria (Rhodospirillum centenum) and Rhodocista pekingensis revealed a remarkable physiological versatility regarding nutrient spectra and survival properties of this genus

ABSTRACT Rhodospirillum centenum is a purple photosynthetic bacterium that is capable of differentiating from vibrioid swimming cells that contain a single polar flagellum into rod-shaped swarming cells that have a polar flagellum plus numerous lateral flagella. Microscopic studies have demonstrated that the polar flagellum is constitutively present and that the lateral flagella are found only when the cells are grown on solidified or viscous medium. In this study, we demonstrated that R. centenum contains two sets of motor and switch genes, one set for the lateral flagella and the other for the polar flagellum. Electron microscopic analysis indicated that polar and lateral flagellum-specific FliG, FliM, and FliN switch proteins are necessary for assembly of the respective flagella. In contrast, separate polar and lateral MotA and MotB motor subunits are shown to be required for motility but are not needed for the synthesis of polar and lateral flagella. Phylogenetic analysis indicates that the polar and lateral FliG, FliM, and FliN switch proteins are closely related and most likely arose as a gene duplication event. However, phylogenetic analysis of the MotA and MotB motor subunits suggests that the polar flagellum may have obtained a set of motor genes through a lateral transfer event.
