NOxvirroista
NOxvirroista is a fictional or speculative term used in theoretical microbiology and science fiction to denote virus-like particles associated with nitrogen oxide chemistry in environmental systems. The name combines NOx, the shorthand for nitrogen oxides, with -virroista, a stylized suffix signaling a virus-like organism. It is not an officially recognized taxon by the International Committee on Taxonomy of Viruses (ICTV), and there are no peer-reviewed reports describing authentic isolates or characterized genomes.
In concept, NOxvirroista are imagined as small virions that may infect prokaryotic hosts involved in nitrogen
Because NOxvirroista lacks formal taxonomic standing, it serves as a placeholder in discussions of virus–environment interactions
