    Dihydroxylycopene diglucoside diesters: a novel class of carotenoids from the phototrophic purple sulfur bacteria Halorhodospira abdelmalekii and Halorhodospira halochloris (2001)
    Springer

    Details
    Publication Date: 2016-05-26
    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.

    Phylogeny of green sulfur bacteria on the basis of gene sequences of 16S rRNA and of the Fenna-Matthews-Olson protein (2002)
    Springer
    In:  Archives of Microbiology, 178 . pp. 131-140.
    Details
    Publication Date: 2019-01-21
    Description: The phylogeny of green sulfur bacteria was studied on the basis of gene sequences of the 16S rRNA and of the Fenna-Matthews-Olson (FMO) protein. Representative and type strains (31 strains total) of most of the known species were analyzed. On the basis of fmoA gene sequences from Chlorobium tepidum ATCC 49652T and Chlorobium limicola DSM 249T available from the EMBL database, primers were constructed that allowed sequence analysis of a major part of the fmoA gene. The largely congruent phylogenetic relationship of sequences of the fmoA gene and of 16S rDNA gives considerable support to the phylogeny of green sulfur bacteria previously suggested on the basis of 16S rDNA sequences. Distinct groups of strains were recognized on the basis of 16S rDNA and FMO sequences and supported by characteristic signature amino acids of FMO. Marine strains formed clusters separate from freshwater strains. The resulting phylogenetic grouping and relationship of the green sulfur bacteria do not correlate with their current taxonomic classification
