Paraferrimonas sedimenticola gen. nov., sp. nov., a marine bacterium of the family Ferrimonadaceae.
Three strains (Mok-106(T), Mok-142 and Mok-143) were isolated from marine sediment samples collected from the coast of Okinawa Island, Japan. On the basis of 16S rRNA gene sequence comparisons, the isolates were affiliated with the family Ferrimonadaceae; Shewanella denitrificans and Ferrimonas balearica were the closest relatives, having sequence similarities of 93.7 and 93.0 %, respectively. The novel isolates shared high levels of 16S rRNA gene sequence similarity with each other (98.7-99.3 %) and the results of DNA-DNA hybridization indicated that the three strains belong to the same species. The cells were rod-shaped, motile by means of single polar flagellum and formed colonies that produced a rose-coloured pigment within 6 days incubation at 25 degrees C. The isolates grew in the presence of 0.5-4.0 % (w/v) NaCl and at 15-40 degrees C. The major fatty acids were iso-13 : 0, iso-15 : 0, 16 : 0, 18 : 1 omega 7c and summed feature 3 (16 : 1 omega 7c and/or iso-15 : 0 2-OH). Menaquinone-6, menaquinone-7 and ubiquinone-8 were the major quinones and the major polar lipids were phosphatidylethanolamine and phosphatidylglycerol. The DNA G+C content was 50-51 mol%. Phylogenetic and phenotypic analyses of these isolates suggested that they belong to a novel genus and species of the family Ferrimonadaceae, for which the name Paraferrimonas sedimenticola gen. nov., sp. nov. is proposed. The type strain is Mok-106(T) (=NBRC 101628(T)=CIP 109284(T)).
