Persephonella atlantica was isolated from a small deep-sea hydrothermal chimney of the Eiffel tower site at Lucky Strike vent field. This small bacteria from the genus Persephonella, little Persephone in Greek, was first discovered in the Pacific Ocean by (Gotz et al, 2002). Persephone was a mythological Greek goddess who spent half of each year in the Underworld and brought fertility as she returned on land.
Persephonella atlantica can grow at a temperature ranging from 50 to 80°C and as for Persephone this bacteria feeds the inhabitants of the hydrothermal ecosystems: Persephonella atlantica uses the oxygen from the surrounding seawater and the reduced elements of the hydrothermal fluid (H2, S°) to fix carbon dioxide. This organic matter feeds to the upper trophic levels like other microorganisms and animals. Metabolically versatile, it will quickly respond to any change in physico-chemical conditions within the chimney by modifying its metabolisms and physiology, adjusting, for intance, its optimal growth temperature.
