Abstract

A halophilic, Gram-negative, motile, non-sporulating bacterium designated strain FB1 was isolated from a wine-barrel-decalcification wastewater. The organism comprises straight rods and has a strictly respiratory metabolism with O. Strain FB1 grows optimally at 20–30 °C and 5–6 % NaCl. The predominant fatty acids were found to be C 9 (30.4 %), C (25.7 %), C 3-OH (10.3 %), C 9 (9.7 %) and C 7 (8.4 %). A phylogenetic analysis based on 16S rRNA gene sequences revealed that the strain forms a coherent cluster within the genus . The highest level of 16S rRNA gene sequence similarity (97.9 %) exhibited by strain FB1 was with the type strain of . However, the level of DNA–DNA relatedness between the novel strain and CIP 107686 was only 31.2 %. The DNA G+C content of strain FB1 was 58.7 mol%. On the basis of phenotypic and genotypic characteristics, and also phylogenetic evidence, strain FB1 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is FB1 (=DSM 17747=CCUG 52119).
