Abstract

The unusual chemo-organoheterotrophic proteobacterial strain MWH-Nonnen-W8red was isolated from a lake located in the Black Forest (Schwarzwald), Germany, by using the filtration-acclimatization method. Phylogenetic analyses based on the 16S rRNA gene sequence of the strain could not provide clear hints on classification of the strain in one of the current classes of the phylum . Whole-genome sequencing resulted in a genome size of 3.5 Mbp and revealed a quite low DNA G+C content of 32.6 mol%. In-depth phylogenetic analyses based on alignments of 74 protein sequences of a phylogenetically broad range of taxa suggested assignment of the strain to a new order of the class . These analyses also suggested that the order should be transferred from the class to the class , that this order should be split into two orders, and that the family should be transferred from the order to the order . We propose to establish for strain MWH-Nonnen-W8red (=DSM 23856=CCUG 58639) the novel species and genus gen. nov., sp. nov. to be placed in the new family fam. nov. of the new order ord. nov.
