Give a brief summary of microbial taxonomy with reference to the classical characteristics employed in microbial classification:
The taxonomy of bacteria consists of nomenclature, classification, and identification of micro-organisms. The rank-based classification of bacteria places within a lower level of a hierarchy of ranks. These ranks range in ascending scale from family to suborder, and upward to order, subclass, class, division/phyla, kingdom, and domain. There are three domains of microorganisms, including the Eukaryotes, Bacteria and Archaea.
