Chiayiivirga Flava Gen. Nov., Sp. Nov., A Novel Bacterium Of The Family Xanthomonadaceae Isolated From An Agricultural Soil, And Emended Description Of The Genus Dokdonella (Vol 63, Pg 3293, 2013)

A novel Gram-reaction-negative, yellow-pigmented, aerobic, non-motile and rod-shaped bacterium designated strain CC-YHH031(T) was isolated from an agricultural soil collected at Chiayi County, Taiwan. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain CC-YHH031(T) formed a discrete monophyletic lineage in the family Xanthomonadaceae, sharing high pairwise sequence similarity of 93.5-95.2 and 94.8% with species of the genus Dokdonella (94.9 % similarity to the type strain of the type species) and Aquimonas voraii GPTSA 20(T), respectively. The genomic DNA G+C content of strain CC-YHH031(T) was 68.6 +/- 0.7 mol% and the predominant respiratory quinone was ubiquinone Q-8. Spermidine was the principal polyamine, with minor amounts of putrescine. Major fatty acids (>5% of total fatty acids) were iso-C-16:0, iso-C-15:0, C-16:1 omega 7c and/or C-16:1 omega 6c (summed feature 3), iso-C-17:1 omega 9C, iso-C-14:0, iso-C-11:0 and iso-C-11:0 3-OH. The polar lipid profile of strain CC-YHH031(T) included phosphatidylethanolamine, phosphatidylmonomethylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, two unidentified aminophospholipids (APL1-2) and four unidentified phospholipids (PL1-4). Strain CC-YHH031(T) was distinguished particularly from the type species of the genus Dokdonella (Dokdonella koreensis) by the presence of major amounts of iso-C-14:0 and summed feature 3 and minor amounts of iso-C-17:0 and by the complete absence of anteiso-C-17:0, the presence of PL1-3 and APL1-2, the absence of APL3 and the presence of putrescine in the former. On the basis of distinguishing genotypic and phenotypic evidence, strain CC-YHH031(T) is proposed to represent a novel genus and species within the family Xanthomonadaceae, for which the name Chiayiivirga flava gen. nov., sp. nov. is proposed. The type strain of Chiayiivirga flava is CC-YHH031(T) (= BCRC 80273(T)=DSM 24163(T)).
