Persephonella Marina
''Persephonella marina'' is a Gram-negative, rod shaped bacteria that is a member of the '' Aquificota'' phylum. Stemming from Greek, the name Persephonella is based upon the mythological goddess Persephone. Marina stems from a Latin origin, meaning "belonging to the sea". It is a thermophile with an obligate chemolithoautotrophic metabolism. Growth of ''P. marina'' can occur in pairs or individually, but is rarely seen aggregating in large groups. The organism resides on sulfidic chimneys in the deep ocean and has never been documented as a pathogen. Discovery ''Persephonella marina'' was first isolated in 1999 using MSH medium, a medium containing 29 g NaCl, 2 g NaOH, 0.5 g KCl, 1.36 g MgCl2•6H2O, 7 g MgSO4•7H2O, 2 g Na2S2O3•5H2O, 0.4 g CaCl2•2H2O, 0.2 g NH4Cl, 0.3 g K2HPO4•3H2O and 10 ml of a trace-element stock solution, with a gas phase containing twenty parts carbon dioxide, one part oxygen, and twenty six parts hydrogen gas. Initial isolation was provided by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aquificota
The ''Aquificota'' phylum is a diverse collection of bacteria that live in harsh environmental settings. The name ''Aquificota'' was given to this phylum based on an early genus identified within this group, ''Aquifex'' (“water maker”), which is able to produce water by oxidizing hydrogen. They have been found in springs, pools, and oceans. They are autotrophs, and are the primary carbon fixers in their environments. These bacteria are Gram-negative, non-spore-forming rods. They are true bacteria (domain Bacteria) as opposed to the other inhabitants of extreme environments, the Archaea. Taxonomy The ''Aquificota'' currently contain 15 genera and 42 validly published species. The phylum comprises a single class and two orders. Aquificales consists of the families Aquificaceae and Hydrogenothermaceae, while the Desulfurobacteriaceae are the only family within the Desulfobacteriales. ''Thermosulfidibacter takaii'' is not assigned to a family within the phylum based on its phylog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
