Complete genome sequence of Nitrosomonas sp. Is79 an ammonia oxidizing bacterium adapted to low ammonium concentrations

摘要

Is79 is a chemolithoautotrophic ammonia-oxidizing bacterium that belongs to the family within the phylum . Ammonia oxidation is the first step of nitrification, an important process in the global nitrogen cycle ultimately resulting in the production of nitrate. Is79 is an ammonia oxidizer of high interest because it is adapted to low ammonium and can be found in freshwater environments around the world. The 3,783,444-bp chromosome with a total of 3,553 protein coding genes and 44 RNA genes was sequenced by the DOE-Joint Genome Institute Program CSP 2006.
