Polynucleobacter hirudinilacicola sp. nov. and Polynucleobacter campilacus sp. nov., both isolated from freshwater systems.

ABSTRACT: Strains MWH-EgelM1-30-B4^T and MWH-Feld-100^T were isolated from the water columns of two freshwater systems. Both strains represent delicate bacteria not easy to work with in laboratory experiments. Phylogenetic analyses of the 16S rRNA genes suggested that both strains were affiliated with the genus Polynucleobacter. Both strains share 16S rRNA gene sequence similarities of >99 % with eight free-living Polynucleobacter type strains, all affiliated with the cryptic species complex PnecC. The full-length 16S rRNA gene sequences of the two strains differ only in two and three positions, respectively, from the sequence of the closest related Polynucleobacter type strain. Genome sequencing of both strains revealed relatively small genome sizes of 2.0 Mbp and G+C contents o
