Description and significance. Bacillus megaterium is a gram positive, endospore forming, rod shaped bacteria. It is considered aerobic. It is found in soil and considered a saprophyte. 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.. megaterium has often been used in the laboratory, and is used as an industrial organism that is able to produce a variety of proteins and sources of bioremediation. Bacillus megaterium is a good source of industrial proteins because it is both a desirable cloning host and produces a large variation of enzymes.
