Query: NC_008686:1960034 Paracoccus denitrificans PD1222 chromosome 1, complete sequence
Lineage: Paracoccus denitrificans; Paracoccus; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria
General Information: This organism is commonly found in soil and sewage sludge. This organism is able to survive in both aerobic and anaerobic environments due to its ability to use both oxygen and nitrogenous oxides making it a popular model organism for the study of electron transfer and and energy conservation.
Subject: NC_010531:428000 Polynucleobacter necessarius STIR1, complete genome
Lineage: Polynucleobacter necessarius; Polynucleobacter; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria
General Information: This strain is an obligate intracellular endosymbiont of the cilliate Euplotes aediculatus. This group of organisms is common in freshwater, comprising up to 60% of the bacteria in freshwater habitats. Polynucleobacter species are also known to be endosymbionts of ciliates. These strains live within the cytoplasm and are essential for their host organisms.
