Bacillus subtilis also known as hay bacillus is a rod-shaped Gram-positive bacteria that produce heat-resistant spores.
Bacillus subtilis can be found in soil, air, and plant compost in conjunction with plants.
They are also found in the gastrointestinal tract of ruminants and humans.
It is typically in the form of a spore and is thought to be inactive.
It creates enzymes when it is active.
Bacillus species are present everywhere in the environment, including soil, water, dust, and air.
Bacillus sp. were formerly thought to be nonpathogenic when isolated from clinical specimens, with the exception of B. anthracis, which causes anthrax.
