Bacillus subtilis (Cell Size).5 um x 3 um. Bacillus megaterium has been industrially employed for more than 50 years, as it possesses some very useful and unusual enzymes and a high capacity for the production of exoenzymes. As a group, this bacteria is observed as jagged branches of opaque white or pale yellow fuzz. Liquid growth: Growth is uniform and solution appears turbid. We also learned about bacteria morphology, which describes what shape bacteria have. B. cereus is mesophilic and is capable of adapting to a wide range of environmental conditions.
