Abstract

A novel Gram-negative strain, designated M-SX103, was isolated from a fresh leaf of Linn. collected at Yuxi City, Yunnan province, China, and subjected to a polyphasic taxonomic study. Growth occurred at 10–40 °C, at pH 6.0–9.0 and with 0–3 % (w/v) NaCl. The predominant isoprenoid quinone was MK-7. The major cellular fatty acids of strain M-SX103 were iso-C, iso-C 3-OH and summed feature 3 (Cω7 and/or Cω6). The G+C content of the genomic DNA was 40.6 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate belongs to the genus , sharing 95.4–89.7 % sequence similarity with type strains of members of the genus ; it was most closely related to T5-12. On the basis of the taxonomic evidence, a novel species, sp. nov., is proposed. The type strain is M-SX103 ( = JCM 17339 = CCTCC AB 2010390).
