    Growth of a photosynthetic bacterium anaerobically in darkness, supported by “oxidant-dependent” sugar fermentation (1978)
    Springer
    Archives of microbiology 117 (1978), S. 119-122 
    Details
    ISSN: 1432-072X
    Keywords: Rhodopseudomonas capsulata ; Fermentation ; Dark, anaerobic growth
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Rhodopseudomonas capsulata can obtain energy for growth from light (anaerobically) and can also grow heterotrophically in darkness using alternative energy conversion modes, namely, aerobic respiration or an unusual type of anaerobic catabolism of sugars. Dark anaerobic growth with fructose as sole carbon and energy source is dependent on the presence of an “accessory” oxidant such as trimethylamine-N-oxide, is accompanied by production of lactate and other classical fermentation products, and yields cells with a high content of photosynthetic pigments and polyhydroxybutyrate.

    Rhodospirillum sodomense, sp. nov., a Dead Sea rhodospirillum species (1993)
    Springer
    Archives of microbiology 160 (1993), S. 363-371 
    Details
    ISSN: 1432-072X
    Keywords: Anoxygenic phototrophic bacteria ; Purple bacteria ; Rhodospirillum sodomense ; Dead Sea ; Hypersaline environments ; Photosynthesis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract A new species of halophilic anoxygenic purple bacteria of the genus Rhodospirillum is described. The new organism, isolated from water/sediment of the Dead Sea, was vibrio-shaped and an obligate halophile. Growth was best at 12% NaCl, with only weak growth occurring at 6% or 21% NaCl. Growth occurred at Mg2+ concentrations up to 1 M but optimal growth was obtained at 0.05–0.1 M Mg2+. Bromide was well tolerated as an alternative anion to chloride. The new organism is an obligate phototroph, growing photoheterotrophically in media containing yeast extract and acetate or a few other organic compounds. Growth of the Dead Sea Rhodospirillum species under optimal culture conditions was slow (minimum td ∼ 20 h). Cells contained bacteriochlorophyll a and carotenoids of the spirilloxanthin series and mass cultures were pink in color. Absorption spectra revealed the presence of a B875 (light-harvesting I) but no B800/B850 (light-harvesting II) photopigment complex. The new organism shares a number of properties with the previously described halophilic phototrophic bacterium Rhodospirillum salinarum and was shown to be related to this phototroph by 16S rRNA sequencing. However, because of its salinity requirements, photosynthetic properties, and isolation from the Dead Sea, the new phototroph is proposed as a new species of the genus Rhodospirillum, R. sodomense.

    Notes: Abstract The complete carotenoid composition of the thermophilic green sulfur bacterium Chlorobium tepidum strain TNO was determined by spectroscopic methods. Major carotenoids were four kinds of carotenes: γ-carotene, chlorobactene, and their 1′,2′-dihydro derivatives (1′,2′-dihydro-γ-carotene and 1′,2′-dihydrochlorobactene). In lesser amounts, hydroxyl γ-carotene, hydroxyl chlorobactene, and their glucoside fatty acid esters were found. The only esterified fatty acid present was laurate, and OH-chlorobactene glucoside laurate is a novel carotenoid. In other strains of C. tepidum, the same carotenoids were found, but the composition varied from strain to strain. The overall pigment composition in cells of strain TNO was 4 mol carotenoids and 40 mol bacteriochlorophyll c per mol bacteriochlorophyll a. The effects of nicotine on carotenoid biosynthesis in C. tepidum differed from those in the thermophilic green nonsulfur bacterium Chloroflexus aurantiacus.

    The major carotenoid in all known species of heliobacteria is the C30 carotenoid 4,4′-diaponeurosporene, not neurosporene (1997)

    Topics: Biology
    Notes: Abstract The carotenoids of five species of heliobacteria (Heliobacillus mobilis, Heliophilum fasciatum, Heliobacterium chlorum, Heliobacterium modesticaldum, and Heliobacterium gestii) were examined by spectroscopic methods, and the C30 carotene 4,4′-diaponeurosporene was found to be the dominant pigment; heliobacteria were previously thought to contain the C40 carotenoid neurosporene. In addition, trace amounts of the C30 diapocarotenes diapolycopene, diapo-ζ-carotene, diapophytofluene, and diapophytoene were also found. Up to now, diapocarotenes have been found in only three species of chemoorganotrophic bacteria, but not in phototropic organisms. Furthermore, the esterifying alcohol of bacteriochlorophyll g from all known species of heliobacteria was determined to be farnesol (C15) instead of the usual phytol (C20). Heliobacteria may be unable to produce geranylgeranyol (C20).

    Evidence for adenylylation/deadenylylation control of the glutamine synthetases of Rhodospirillum tenue and Rhodocyclus purpureus (1985)

    ISSN: 1432-072X
    Keywords: Phototrophic bacteria ; Rhodospirillaceae ; Glutamine synthetase ; Nitrogen metabolism ; Nitrogen fixation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The phylogenetically related phototrophic bacteria Rhodospirillum tenue and Rhodocyclus purpureus modulate activity of their glutamine synthetases by adenylylation/deadenylylation. Evidence for covalent modification includes the inhibitory effect of Mg2+ on the activity of glutamine synthetase extracted from cells of either species grown on excess ammonia, and the lack of Mg2+ inhibition of activity of the enzyme isolated from N2-(R. tenue) or glutamine (R. purpureus)-grown cells. In addition, snake venom phosphodiesterase treatment of glutamine synthetase from either species grown on excess ammonia relieved Mg2+ inhibition of the enzyme (as measured via the γ-glutamyl transferase assay), and changed the cation specificity from Mn2+ to Mg2+ (in the biosynthetic assay).

    Nutritional studies on Chloroflexus, a filamentous photosynthetic, gliding bacterium (1974)
    Springer

    ISSN: 1432-072X
    Keywords: Filamentous, Photosynthetic Bacteria ; Nutritional Studies ; Gliding Bacteria
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Nutritional studies on four different strains of Chloroflexus, a new genus of filamentous, photosynthetic bacteria are described. This organism appears to be related to several different procaryotic groups, and in particular to the green sulfur bacteria and blue-green algae. Unlike these autotrophs, however, Chloroflexus is nutritionally diverse, being able to grow aerobically as a light-independent heterotroph, and anaerobically as a photoautotroph or photoheterotroph. Numerous organic carbon sources including hexoses, amino acids, short chain fatty acids, organic acids, and some alcohols are utilized under various growth conditions. These results suggest that this organism may be among the most nutritionally versatile organisms known.

    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Enrichment cultures for heliobacteria at 50°C yielded several strains of a thermophilic heliobacterium species from Yellowstone hot spring microbial mats and volcanic soils from Iceland. The novel organisms grew optimally above 50°C, contained bacteriochlorophyll g, and lacked intracytoplasmic membranes. All isolates were strict anaerobes and grew best as photoheterotrophs, although chemotrophic dark growth on pyruvate was also possible. These thermophilic heliobacteria were diazotrophic and fixed N2 up to their growth temperature limit of 56°C. Phylogenetic studies showed the new isolates to be specific relatives of Heliobacterium gestii and, as has been found in H. gestii, they produce heat-resistant endospores. The unique assemblage of properties found in these thermophilic heliobacteria implicate them as a new species of this group, and we describe them herein as a new species of the genus Heliobacterium, Heliobacterium modesticaldum.

    Heliophilum fasciatum gen. nov. sp. nov. and Heliobacterium gestii sp. nov.: endospore-forming heliobacteria from rice field soils (1996)

    Keywords: Key words Anoxygenic phototrophic bacteria ; Heliophilum fasciatum ; Heliophilum gestii ; Bacteriochlorophyll g ; Photosynthesis ; Rice fields

    Topics: Biology
    Notes: Abstract Two new taxa of phototrophic heliobacteria are described: Heliobacterium gestii sp. nov. and Heliophilum fasciatum gen. nov. sp. nov. Both organisms were isolated from dry paddy soils. Cells of H. gestii were motile spirilla; cells of H. fasciatum formed cell bundles that were motile as units. Both organisms produced endospores; H. gestii endospores contained dipicolinic acid and elevated levels of calcium. As with other heliobacteria, bacteriochlorophyll g was produced in both organisms and no intracytoplasmic photosynthetic membranes were observed. Growth of H. gestii and H. fasciatum occurred under both photoheterotrophic and chemotrophic conditions; nitrogen fixation also occurred in both organisms. H. gestii and H. fasciatum showed a phylogenetic relationship to the "low GC" line of gram-positive Bacteria, but H. fasciatum was distinct from H. gestii and all other heliobacteria. The ability of H. gestii and H. fasciatum to form endospores might be a significant ecological advantage for survival in their rice soil habitat.
