(TTC, a tetrazolium salt is used by bacteria as an electron transporter, in its oxidized form it is colorless and soluble, while in its reduced form it is insoluble and red).
(staphylococcus bacteria are spherical and clustered like grapes, the Bacillus bacteria are rod-shaped)
(Anabaena is the filamentous bacteria and contains heterocyst cells that are able to fix the atmospheric nitrogen)
(the word is related to water blooms)
(chlamydiae in their outer membrane contains lipopolysaccharide and membrane proteins but have the only detectable presence of peptidoglycans. Earlier it was thought that peptidoglycans are absent in chlamydiae)
(The genes for peptidoglycan are not absent rather they are turned off)
(Proteobacteria is the largest phylum of bacteria and consists of a wide variety of pathogenic bacteria)
(it includes various genera pathogenic genera like Escherichia, Salmonella, Vibrio, Helicobacter, Shigella, Spirillum, etc and genera responsible for nitrogen fixation. Thus the five key genera belong to proteobacteria).
(similar species are placed into the same genera)
(genera with similar characters are placed in a taxonomic family)
(All the related families are placed into the same order).
