The Isolation and Some Characteristics of Photosynthetic Bacteria ( Chromatiaceae and Chlorobiaceae ) from Antarctic Marine Sediments [PDF]

open access: yesJournal of Applied Bacteriology, 1977
Sediment samples taken at depths from 5 to 50 m in Borge Bay, Signy Island, Antarctica yielded purple ( Chromatiaceae ) and green ( Chlorobiaceae ) phototrophic bacteria when inoculated into Winogradsky columns or directly into Pfennig's medium.

Capacity of chromatiaceae for chemotrophic growth. Specific respiration rates of Thiocystis violacea and Chromatium vinosum

Archives of Microbiology, 1980
The capacity for chemoautotrophic, mixotrophic and organotrophic growth in the dark was tested with 45 strains of 17 species (11 genera) of the Chromatiaceae. The auxanographic deep agar shake culture method was used; the gas phase contained 5% O2 and 1% CO2 in N2. All strains tested of Chromatium vinosum, C. minus, C. violascens, C.

Isolation and characterization of some chemoautotrophic Chromatiaceae

Journal of Basic Microbiology, 1986
AbstractThree strains of facultatively chemoautotrophic Chromatiaceae were isolated from natural habitats under chemotrophic conditions and identified as Chromatium gracile (strains 23‐3 and 25‐1) and Thiocapsa roseopersicina (strain Laboe). The strains utilized hydrogen and reduced sulfur compounds for photo‐ and chemolithoautotrophic growth. Ammonium

Utilization of nitrogen compounds and ammonia assimilation by chromatiaceae

Archives of Microbiology, 1977
Chromatium vinosum strain D, Thiocapsa roseopersicina strain 6311 and Ectothiorhodospira mobilis strain 8112 were grown anaerobically in the light with various single nitrogen sources. When substituted for NH4Cl only glutamine and casamino acids supported good growth of all strains tested. Peptone and urea were utilized by C.

Ecology and Osmoadaptation of Halophilic Chromatiaceae in Hypersaline Environments

1999
The Chromatiaceae observed to date in hypersaline environments were found in microbial mats which develop in solar salterns. These salterns are man-made structures based on a succession of shallow ponds in which seawater circulates and evaporates until the NaC1 concentration reaches saturation, with resulting precipitation and crystalisation ...

Characterization of Chromatium salexigens sp. nov., a Halophilic Chromatiaceae Isolated from Mediterranean Salinas

Systematic and Applied Microbiology, 1988
Summary In the course of ecological studies in salinas and salt-works of Salin de Giraud (Camargue, France), a halophilic strain of the Chromatiaceae was isolated from a red layer below the gypsum crust. Because of its morphology, this strain (SG 3201) was assigned to the genus Chromatium , resembling Chromatium buderi and Chromatium vinosum ...
