Bacillus megaterium is latin for the big beast because it is an extremely large bacteria, it is about 100 times as large as E. coli.Due to its immense size, about 60 micrometers cubed, B. megaterium has been used to study structure, protein localization and membranes of bacteria since the 1950âs.acillus megaterium is latin for the big beast because it is an extremely large bacteria, it is about 100 times as large as E. coli.
