^aEvidence codes—TAS Traceable Author Statement (i.e., a direct report exists in the literature), NAS Non-traceable Author Statement (i.e., not directly observed for the living, isolated sample, but based on a generally accepted property for the species, or anecdotal evidence). Evidence codes are from the Gene Ontology project [31]. ^bShape of cells varies between cocci and straight or slightly curved rods depend on NH₄Cl concentration [6]
