Lysobacter lycopersici sp. nov., isolated from tomato plant Solanum lycopersicum.

A Gram-stain negative, aerobic, rod-shaped and non-spore-forming bacterium, CC-Bw-6 was isolated from chopped tomato stems. Analysis of the 16S rRNA gene sequence of the strain CC-Bw-6 showed its affiliation with the genus Lysobacter within the class Gammaproteobacteria. Strain CC-Bw-6 was found to be most closely related to Lysobacter panaciterrae KCTC 12601 (97.0 %) and Lysobacter daecheongensis KCTC 12600 (96.8 %), and showed lower similarity (<96.5 %) to other Lysobacter species. DNA-DNA relatedness between strain CC-Bw-6 and L. panaciterrae KCTC 12601 was 10.8 %, the G+C content of the genomic DNA is 69.9 mol%. Strain CC-Bw-6 was determined to possess C iso, C iso 3OH, C iso, C anteiso, C ω5c, C ω5c, C, C iso, C iso, C iso and C 10-methyl/C iso ω9c as predominant fatty acids. The major polar lipid profile consists of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and unidentified phospholipids. The predominant polyamine is spermidine, and ubiquinone-8 is the predominant respiratory quinone. Analysis of phenotypic, geno- and phylogenetic characteristics revealed a distinct taxonomic position of strain CC-Bw-6 with respect to other Lysobacter species. Based on the phylogenetic, chemotaxonomic and phenotypic data presented here, we propose a novel species with the name Lysobacter lycopersici sp. nov. The type strain is CC-Bw-6 (=BCRC 80612 = JCM 19164). [ABSTRACT FROM AUTHOR]
