Abstract:
A bacterial strain, designated HOR6-4 T , was isolated from the epidermal tissue of a root of a Phalaenopsis orchid. Strain HOR6-4 T was characterized using a polyphasic approach. The cells were aerobic, Gram-stain-positive, non-motile coccoids. Phylogenetic analysis of its 16S rRNA gene sequence revealed a clear affiliation with the family Dermacoccaceae . Strain HOR6-4 T showed relatively low 16S rRNA gene sequence similarity (below 95.9 %) to type strains of species with validly published names, showing the highest sequence similarities to the type strains of Flexivirga alba (95.8 %) and Yimella lutea (95.5 %). The DNA G+C content of strain HOR6-4 T was 64.7 mol%. Strain HOR6-4 T had anteiso-C 17 : 0 (19.3 %), 10-methyl C 18 : 0 (tuberculostearic acid; 13.5 %) and 10-methyl C 17 : 0 (11.7 %) as the major fatty acids and contained MK-8(H 4 ) and MK-8(H 6 ) as the predominant quinones. Polar lipids were diphosphatidylglycerol, phosphatidylinositol, three aminophospholipids, two phospholipids and an aminolipid. The peptidoglycan type was A4α, with an l -Lys– l -Thr– d -Glu interpeptide bridge with a glycine residue bound to the alpha-carboxyl group of d -Glu in position 2 of the peptide subunit. Mycolic acids were not present. On the basis of comparative analysis of phenotypic and phylogenetic traits, strain HOR6-4 T is considered to represent a novel species in a new genus in the family Dermacoccaceae , for which the name Rudaeicoccus suwonensis gen. nov., sp. nov. is proposed. The type strain of Rudaeicoccus suwonensis is HOR6-4 T ( = KACC 12637 T = DSM 19560 T ).
