Desulfovibrio frigidus sp. nov. and Desulfovibrio ferrireducens sp. nov., psychrotolerant bacteria isolated from Arctic fjord sediments (Svalbard) with the ability to reduce Fe(III)
Udgivelsesdato: 2006-Apr Strains 18T, 61T and 77 were isolated from two permanently cold fjord sediments on the west coast of Svalbard. The three psychrotolerant strains, with temperature optima at 20-23 degrees C, were able to grow at the freezing point of sea water, -2 degrees C. The strains oxidi...

Strain 61T was closely related to strains 18T and 77 (97.6 and 97.5 % 16S rRNA gene sequence similarity), but on the basis of DNA-DNA hybridization strain 61T represents a novel species for which the name Desulfovibrio ferrireducens sp. nov. is proposed. The type strain is strain 61T (=DSM 16995T = JCM 12925T).
