In the scientific classification established by Carl von Linne, linnÃ© 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). domainacterial taxonomy is the taxonomy, i.e. the rank-based classification, of bacteria.
Bacillus Subtilis. Bacillus subtilis, as with many in the Bacillus genus, is an extremely common bacterium. It is found in soil, water, air, and decomposing plant matter.Bacteria in the Bacillus genus are spore-forming, which means that they create a thick wall which surrounds their DNA and other internal cell structures.acillus subtilis is also used as a fungicide. The bacteria colonize the root system, leaving no room for fungal disease organisms. It is used on agricultural seeds of vegetables, soybeans, cotton, and peanuts and on flower and ornamental seeds.
