Paramoritella sediminis sp. nov., isolated from marine sediment, and emended descriptions of the genus Paramoritella Hosoya et al. 2009 and Paramoritella alkaliphila.

A Gram-negative, facultatively anaerobic, rod-shaped (2.04-1.27 × 0.95-1.25 µm) and motile marine bacterium, designated MEBiC06500(T) was isolated from sediment collected at Daebu Island in the Yellow Sea (37° 20' N 126° 41' E), Korea. 16S rRNA gene sequence analysis revealed that strain MEBiC06500(T) showed high similarity with Paramoritella alkaliphila A3F-7(T) (96.5%). Growth was observed at 10.5-30.2 °C (optimum 23.5 °C), at pH 6.0-9.5 (optimum 8.0) and with 0-5% (optimum 1.5%) NaCl. The predominant cellular fatty acids were C14:0, C16:0, C18:1ω7c and summed feature 3 (iso-C15:0 2-OH and/or C16:1ω7c). The DNA G+C content was 56.0 mol%. The respiratory quinone is Q-8. Phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, four unidentified lipids, one unidentified phospholipid and three unidentified aminolipids were detected as major polar lipids. On the basis of this polyphasic taxonomic data, strain MEBiC06500(T) should be classified as a representative of a novel species in the genus Paramoritella, and the proposed name is Paramoritella sediminis sp. nov. The type strain is MEBiC06500(T) (=KCCM 42977(T)=JCM 18292(T)). Emended descriptions of the genus Paramoritella Hosoya et al. 2009 and Paramoritella alkaliphila are also given.
