Bacterial taxonomy Bacterial taxonomy Bacterial taxonomy is the taxonomy, i.e. the rank-based classification, of bacteria. In the scientific classification established by Carl Linnaeus, each species has to be assigned to a genus (binary nomenclature), which in turn is a lower level of a hierarchy of ranks (family, suborder, order, subclass, class, division/phyla, kingdom and domain). In the currently accepted classification of life, there are three domains (Eukaryotes, Bacteria and Archaea), which, in terms of taxonomy, despite following the same principles have several different conventions between them and between their subdivisions as are studied by different disciplines (botany, zoology, mycology and microbiology), for
Linnaean taxonomy Linnaean taxonomy Linnaean taxonomy can mean either of two related concepts: Linnaean name also has two meanings: depending on the context, it may either refer to a formal name given by Linnaeus (personally), such as "Giraffa camelopardalis" Linnaeus, 1758, or a formal name in the accepted nomenclature (as opposed to a modernistic clade name). In his "Imperium Naturae", Linnaeus established three kingdoms, namely "Regnum Animale", "Regnum Vegetabile" and "Regnum Lapideum".
