sp. nov., a marine bacterium isolated from the South China Sea Free

Abstract

A novel, aerobic, heterotrophic, orange-pigmented, Gram-staining-negative, rod-shaped, gliding bacterial strain, designated JLT2000, was isolated from surface water of the South China Sea. The strain was oxidase- and catalase-positive. The major cellular fatty acids of strain JLT2000 were C, iso-C G, iso-C, iso-C 3-OH, summed feature 3 (comprising Cω7c and/or Cω6), C and C. MK-7 was the major respiratory quinone and the major polar lipids were phosphatidylcholine and phosphatidylethanolamine. The genomic DNA G+C content of strain JLT2000 was 37.9 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain JLT2000 formed a branch within the genus , but was clearly separated from the two established species of this genus, and . The 16S rRNA gene sequence similarity of strain JLT2000 with the type strains of these two species was 95.8 % and 96.1 %, respectively. Strain JLT2000 had a shorter cell length and wider growth range in different temperatures and salinities than those of NBRC 15989 and NBRC 15983. In addition, strain JLT2000 could utilize more carbon sources and hydrolyse more polymers than NBRC 15989 and NBRC 15983. Based on this polyphasic analysis, strain JLT2000 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is JLT2000 ( = JCM 18012 = CGMCC 1.10832).
