Ferrimonas balearica DSM 9799

Ferrimonas balearica (strain DSM 9799 / CCM 4581 / PAT) is a motile, facultatively anaerobic, non spore-forming Gram-negative bacterium isolated from the upper few centimeters of marine sediment of the Palma de Mallorca harbor, Spain. This is the first completed genome sequence of a member of the genus Ferrimonas. The generic name derives from the Latin word "ferrum" meaning "iron" and the Greek word "monas" meaning "unit", referring to an iron(III)-reducing cell. The cells are straight rods with rounded ends and appear singly, occasionally in pairs or short chains and usually not encapsulated. F. balearica is motile by means of monotrichous flagella. Colonies produce a black iron precipitate when the cells are grown on TSI agar, and are often brown and mucous when the cells are grown under aerobic conditions. F. balearica is of special interest because it is a chemoorganotroph and has a strictly respiratory metabolism with oxygen, nitrate, Fe(III)-oxyhydroxide, Fe(III)-citrate, MnO2, selenate, selenite and thiosul-fate as electron acceptors F. balearica requires a minimum of 0.5% NaCl for growth, with a range of NaCl tolerance of 0.5%-7.5%. It does not grow at 5 or 44 degrees Celsius but does grow at 42 degrees Celsius. The pH range for growth is 6-9. The genus Ferrimonas can be distinguished from other strictly respiratory Gram-negative genera of the Gammaproteobacteria based on its ability to reduce Fe(III), denitrification, growth at 42 degrees Celsius, presence of phenylalanine deaminase activity, inability to grow in NaCL-free media, lack of gelatinase, urease and a negative reaction of Simmons citrate test.
