    Notes: A PCR protocol for the detection of sulfur-oxidizing bacteria based on soxB genes that are essential for thiosulfate oxidation by sulfur-oxidizing bacteria of various phylogenetic groups which use the ‘Paracoccus sulfur oxidation’ pathway was developed. Five degenerate primers were used to specifically amplify fragments of soxB genes from different sulfur-oxidizing bacteria previously shown to oxidize thiosulfate. The PCR yielded a soxB fragment of approximately 1000 bp from most of the bacteria. Amino acid and nucleotide sequences of soxB from reference strains as well as from new isolates and environmental DNA from a hydrothermal vent habitat in the North Fiji Basin were compared and used to infer relationships of soxB between sulfur-oxidizing bacteria belonging to various 16S rDNA-based phylogenetic groups. Major phylogenetic lines derived from 16S rDNA were confirmed by soxB phylogeny. Thiosulfate-oxidizing green sulfur bacteria formed a coherent group by their soxB sequences. Likewise, clearly separated branches demonstrated the distant relationship of representatives of α-, β-, and γ-Proteobacteria including representative species of the former genus Thiobacillus (now Halothiobacillus–γ-Proteobacteria, Thiobacillus–β-Proteobacteria and Starkeya–α-Proteobacteria). This general picture emerged although apparent evidence for lateral transfer of the soxB gene is indicated and comparison of soxB phylogeny and 16S rDNA phylogeny points to the significance of this gene transfer in hydrothermal vent bacterial communities of the North Fiji Basin.

    Description: The carotenoids in Halorhodospira abdelmalekii and Halorhodospira halochloris were analyzed by spectroscopic methods. The carotenoid composition of the two species was almost the same. Both species contained substantial amounts of unusual carotenoid glycoside fatty acid esters, which have been found for the first time in phototrophic purple bacteria. Methoxy-hydroxylycopene glucoside was a major component, and dihydroxylycopene diglucoside and dihydroxylycopene diglucoside diester were also found. Lycopene, rhodopin, and 3,4,3′,4′-tetrahydrospirilloxanthin were present in very small amounts. Methoxy, glucosyl, and glucosyl ester groups were observed as substituents at the positions of the two original hydroxyl groups of dihydroxylycopene and made up approximately 20, 50, and 20%, respectively, of the total end groups (100%). The fatty acid components of the three carotenoid glucoside esters were the same (C12:0 and C14:1) and were rare in the cellular lipids of the two species

    True marine and halophilic anoxygenic phototrophic bacteria (2001)
    Springer
    In:  Archives of Microbiology, 176 . pp. 243-254.
    Details
    Publication Date: 2016-05-26
    Description: Anoxygenic phototrophic bacteria are widely distributed in marine sediments and shallow waters of the coastal zone, where they often form intensely colored mass developments. The phototrophic bacteria have adapted to the whole spectrum of salt concentrations, from freshwater to saturated brines, and it is apparent that individual species have adapted well to particular habitats and mineral salts compositions, both qualitatively and quantitatively. This adaptation is reflected not only in the demand for defined ranges of salt concentrations, but also in the phylogenetic relationships of these bacteria, as established by 16S rDNA sequences. Major phylogenetic branches of purple sulfur bacteria are represented by: (1) marine and extremely halophilic Ectothiorhodospiraceae, (2) truly marine and halophilic Chromatiaceae and (3) freshwater Chromatiaceae, some of which are tolerant to low salt concentrations and are successful competitors in brackish and marine habitats. Quite similarly, salt-dependent green sulfur bacteria form distinct phylogenetic lines. In addition, also among the phototrophic α-Proteobacteria (purple nonsulfur bacteria), distinct phylogenetic lines of salt-dependent species are recognized. Available data give rise to the assumption that salt concentrations of natural habitats are an important selective factor that determines the development of a selected range of phototrophic bacteria in an exclusive way. As a consequence, the salt responses of these bacteria are reflected in their phylogenetic relationships

    Genetic analysis of sea-ice bacterial communities of the Western Baltic Sea using an improved double gradient method (2001)
    Springer
    In:  Polar Biology (4). pp. 252-257.
    Details
    Publication Date: 2016-11-09
    Description: The bacterial diversity of sea ice from Kiel Bight obtained during the rare event of solid ice cover in spring 1996 was analysed by molecular genetic approaches using an improved double gradient denaturing gradient gel electrophoretic method (DG-DGGE) to separate 16S rDNA fragments of approximately 500 bp. The excellent separation of individual bands within these gradient gels allowed us to obtain sequence information and to allocate the phylogenetic position of representative bacteria from the sea ice. The band pattern of the gradient gels revealed a vertical stratification of the bacterial species distribution within the ice and the presence of characteristic bacteria for each layer. According to their 16S rDNA sequences, major bands of the gradient gels represented bacteria closely related to fermenting species of the genera Propionibacterium and Bacteroides and to anoxygenic phototrophic purple sulfur bacteria (Chromatiaceae). Their abundance in horizons of the inner ice core may indicate the existence of oxygen-deficient and anoxic zones or niches and possible primary production by anoxygenic photosynthesis within the investigated Baltic Sea sea ice. This is the first phylogenetic evidence of the presence, and most probably the development, of phototrophic purple sulfur bacteria in sea ice.
