Summary of "sp. nov. and sp. nov., two marine bacteria isolated from the East China Sea."

Two Gram-staining-negative, facultatively anaerobic, motile, short clavate and flagellated marine bacteria, designated strains BEI233 and LJC006, were isolated from the East China Sea. On the basis of the results of 16S rRNA gene sequencing and multilocus sequence analysis, BEI233 and LJC006 should be assigned to the genus . The closest phylogenetic relatives of BEI233 are LMG 19158 (98.7 % 16S rRNA gene sequence pairwise similarity), DSM 14397 (98.5 %), KCTC 42287 (97.7 %), ATCC 35048 (97.3 %) and MD16 (96.5 %), whereas for LJC006 they were CAIM 518 (97.1 %), LMG 7894 (97.0%), JCM 16456 (96.9 %) and LMG 21346 (96.1 %). The growth of BEI233 occurred at 10-37 °C, pH 5.0-8.0 and with 1-7 % (w/v) NaCl, while the growth of LJC006 occurred at 10-37 °C, pH 6.0-9.0, and 0-8 % (w/v) NaCl. The predominant fatty acids (>10 %) were summed feature 3 (Cω7 or/and Cω6), C and summed feature 8 (Cω7 or/and Cω6), with different proportions. The DNA G+C contents of BEI233 and LJC006 are 42.41 mol% and 41.88 mol%, respectively. On the basis of the results of polyphasic analysis, BEI233 and LJC006 are considered to represent novel species of the genus for which the names sp. nov. and sp. nov. are proposed. The type strains are BEI233 (=JCM 32692=KCTC 62618) and LJC006 (=JCM 32693=KCTC 62620), respectively.
