Capsules The capsules of many bacilli, including B. anthracis, B. subtilis, B. megaterium, and B. licheniformis, contain poly-D- or L-glutamic acid. Other Bacillus species, e.g., B. circulans, B. megaterium, B. mycoides and B. pumilus, produce carbohydrate capsules.tructure of the muropeptide subunit of the peptidoglycan of Bacillus megaterium. In most Bacillus species, an interpeptide bridge that connects D-alanine to meso-diaminopimelic acid (DAP) is absent. In addition, all Bacillus spores contain this type of muramic acid subunit in the spore cortex.
