Habitat

This species is commonly found in the upper layers of the soil and B. subtilis is thought to be a normal gut commensal in humans. A 2009 study compared the density of spores found in soil (about 10⁶ spores per gram) to that found in human feces (about 10⁴ spores per gram). The number of spores found in the human gut was too high to be attributed solely to consumption through food contamination. In some bee habitats, B. subtilis appears in the gut flora of honey bees. B. subtilis can also be found in marine environments.
