Abstract

Strains YIM M 10366, YIM M 10378 and YIM M 10400 were isolated from marine sediments collected from the Xisha Islands in the South China Sea. All three isolates were able to grow optimally at pH 7.0, 28–37 °C and 0–3 % (w/v) NaCl. Comparison of 16S rRNA gene sequences showed that these strains are members of the genus , exhibiting moderately high 16S rRNA gene sequence similarities of 97.0–98.8 % to members of the most closely related species. Morphological characteristics, physiological characteristics and compositions of whole-cell sugars and phospholipids are consistent with the diagnostic characteristics of the genus , but still allowed differentiation amongst the three strains and their neighbours. Based on 16S rRNA gene sequence analysis, DNA–DNA relatedness, phenotypic characteristics and chemotaxonomic data, strains YIM M 10366, YIM M 10378 and YIM M 10400 were identified as members of three novel species of the genus , for which the names sp. nov. (type strain YIM M 10366  = DSM 42021  = CCTCC AA2010005), sp. nov. (type strain YIM M 10378  = DSM 42022  = CCTCC AA 2010006) and sp. nov. (type strain YIM M 10400  = DSM 42024  = CCTCC AA 2010008) are proposed.
