Microbial Classification is the science that studies organisms to arrange them into groups, or taxa. Three separate but interrelated areas of taxonomy are: ______
Identification, Process of characterizing in order to group, Classification, Arranging organisms into similar or related groups, Nomenclature, System of assigning names
1978 Carl Woese proposed three domains based on: Cell wall, Membrane lipids, RNA sequence, Protein synthesis, Antibiotic sensitivity. Three Domains Naming Microorganisms Binomial nomenclature Used worldwide A system of naming organisms first proposed in the 1700s by Swedish scientist Carolus Linnaeus. Each organism is given two Latinized names: Genus – Capitalized Species - lowercase Both italicized or underlined ______
