Taxonomy

Description
In accordance with other members of Nitrososphaerales, Nitrosocosmicus franklandianus (formally franklandus) is an ammonia oxidising archaeon, isolated from a terrestrial environment, demonstrating the characteristic irregular coccoid cell morphology associated with this order. As with Nitrososphaera viennensis, it is able to grow on urea but it can tolerate higher ammonium concentrations, equivalent to those tolerated by chemolithoautotrophic bacterial ammonia oxidisers. It represents an ecologically relevant strain of the phylum Nitrososphaerota/Thermoproteota with the potential to compete successfully with ammonium oxidising bacteria in fertilised soils where ammonium concentrations are high.

Submitter comments
The genome was assembled using SPAdes and Canu, using default settings for both MinION and Illumina data. For the MinION data, Nanopolish was used to improve the consensus sequence. The assembly resulted in three large contigs which were aligned against the closest reference genomes to allow prediction of the orientation of the three contigs, and gaps were subsequently closed by long-range PCR and Sanger sequencing. Genome annotation and analysis was performed using the MicroScope platform (GenoScope).
