Pacificamonas flava gen. nov., sp. nov., a Novel Member of the Family Sphingomonadaceae Isolated from the Southeastern Pacific

Strain JLT2015T was isolated from surface seawater of the Southeastern Pacific. The strain was Gram-negative, aerobic, motile by gliding, and rod shaped. The dominant fatty acids were C18:1ω7c, C16:0, and C16:1ω7c. The major respiratory ubiquinone was Q-10, and the predominant polyamine pattern was spermidine. The components of the polar lipid profile were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, and sphingoglycolipid. The DNA G+C content was 64.2 %. Phylogenetic analysis based on 16S rRNA gene sequence revealed strain JLT2015T belonged to belong to the family Sphingomonadaceae, exhibiting 94.7 % 16S rRNA gene sequence similarity with Novosphingobium pentaromativorans. On the basis of the taxonomic data presented, together with phylogenetic and genetic characteristics, strain JLT2015T is considered to represent a novel genus, for which the name Pacificamonas flava gen. nov., sp. nov. is proposed. The type strain of Pacificamonas flava is JLT2015T (=LMG27364T = CGMCC1.12401T).
