gen. nov., sp. nov. isolated from bottled mineral water.

Two isolates, designated B15.09-116 and B15.09-124, were recovered from bottled mineral water in Portugal. Based on 16S rRNA gene sequence analysis, these strains were related most closely to species of the genus (belonging to the family ) with pairwise sequence similarities of 93.0-93.6 %. The isolates were not pigmented and formed Gram-stain-negative, short, motile rod-shaped cells. The organisms were strictly aerobic, oxidase-positive and catalase-negative. These organisms also fixed N. The major polar lipids were phosphatidylglycerol and phosphatidylethanolamine. Ubiquinone 8 was the major respiratory quinone. The DNA G+C content of strain B15.09-116 was 49.8 mol%. Based on phylogenetic, physiological and biochemical characteristics the two strains are considered to represent a novel species of a new genus, for which the name gen. nov., sp. nov. is proposed. The type strain of is B15.09-116 ( = CECT 8581 = LMG 28208).
