sp. nov. and sp. nov., isolated from soil Free

Abstract

Two Gram-reaction-negative, rod-shaped, gliding, yellow-pigmented bacterial strains, designated ZLD-17 and ZLD-29, were isolated from arid soil samples collected from Xinjiang Province, north-west China, and subjected to analysis using a polyphasic taxonomic approach. Both novel strains required 1.0–2.0 % (w/v) sea salts for optimal growth. Phylogenetic analysis based on 16S rRNA gene sequences indicated that these two strains belong to the genus within the class . Strain ZLD-17 showed highest 16S rRNA gene sequence similarities to KCTC 22007 (96.9 %), DSM 21749 (96.8 %) and KCTC 12204 (96.8 %), whereas strain ZLD-29 showed highest sequence similarities to DSM 18481 (96.0 %) and DSM 2043 (95.9 %). 16S rRNA gene sequence similarity between ZLD-17 and ZLD-29 was 96.1 %. The DNA GC contents of strains ZLD-17 and ZLD-29 were 67.9 and 68.2 mol%, respectively. The major cellular fatty acids of both strains were summed feature 3 (iso-C 2-OH and/or Cω7), iso-Cω9, iso-C, C and iso-C 3-OH; their predominant isoprenoid quinone was Q-8 and their major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. Based on their phenotypic characteristics, phylogenetic position as determined by 16S rRNA gene sequence analysis and chemotaxonomic data, strains ZLD-17 ( = CCTCC AB 207174  = KCTC 23076) and ZLD-29 ( = CCTCC AB 207175 = KCTC 23077) represent two novel species of the genus , for which the names sp. nov. and sp. nov. are proposed, respectively.
