Polynucleobacter necessarius subsp. asymbioticus Hahn et al. 2009 is one of currently two subspecies of P. necessarius. While P. necessarius subsp. asymbioticus is a free-living bacterium, the closely related second subspecies, P. necessarius subsp. necessarius is an obligate endosymbiont living in the cytoplasm of freshwater ciliates of the genus Euplotes aediculatus. The two P. necessarius subspecies were the closest thus far reported phylogenetic neighbors that differ in their lifestyle as obligately free-living vs. obligate endosymbiontic, and they are the only members of the genus Polynucleobacter with completely sequenced genomes. The genome-sequenced strain represents a group of closely related strains not distinguishable by 16S rRNA, 16S-23S ITS or glnA sequences, which is persistent in the home habitat of the strain and frequently contributes > 10% of total bacterial numbers in water samples of the habitat. The 2,159,490 bp long chromosome with a total of 2,088 protein-coding and 48 RNA genes was sequenced as part of the DOE Joint Genome Institute Community Sequencing Program 2006.
