Kinneretia asaccharophila gen. nov., sp. nov., isolated from fresh water of Lake Kinneret, Israel: a novel member of the Rubrivivax-branch of the family Comamonadaceae

Abstract

A strictly aerobic, Gram-negative bacterium, strain KIN192T, isolated from fresh water from Lake Kinneret, Israel, was examined using a polyphasic approach to characterize and clarify its phylogenetic and taxonomic position. Sequences of the 16S rRNA and gyrB genes and ITS1 revealed close relationships to species of the genera Pelomonas, Mitsuaria and Roseateles, in the Rubrivivax branch of the family Comamonadaceae of the Betaproteobacteria. Physiological and biochemical tests, cellular fatty acid analysis and DNA-DNA hybridizations indicated that this strain should be assigned to a new genus and species in the Rubrivivax phylogenetic branch, for which the name Kinneretia asaccharophila gen. nov., sp. nov., is proposed. The type strain of Kinneretia asaccharophila is strain KIN192T (=CCUG 53117T =CECT 7319T). © 2010 IUMS.
