Luteimonas cucumeris sp. nov., isolated a from cucumber leaf
A Gram-negative, aerobic and non-motile rod, designated Y4T, was isolated from a cucumber leaf from Pinggu District, east Beijing, PR China. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain Y4T was most closely related to Luteimonas aquatica RIB1-20T (96.7 % 16S rRNA gene sequence similarity). DNA–DNA relatedness between strain Y4T and L. aquatica RIB1-20T was 42.5±3.9 %. The predominant fatty acids were iso-C15 : 0, iso-C17 : 1ω9c, iso-C16 : 0 and iso-C17 : 0. The major ubiquinone was Q-8. The DNA G+C content of the type strain was 69.9 mol%. Based on the evidence above, strain Y4T represents a novel species of the genus Luteimonas , for which the name Luteimonas cucumeris sp. nov. is proposed. The type strain is Y4T ( = CGMCC 1.10821T = KCTC 23627T).
