Bacillus subtilis, also known as hay bacillus or grass bacillus, is one of the first Gram-positive bacteria to be studied. It is an aerobic, rod-shaped spore-forming microorganism that can survive in extreme conditions such as cold, heat, and even disinfected environments. This bacterium is found predominantly in soil and in association with plants, and it is the type species for the genus Bacillus.
Morphologically, Bacillus subtilis is characterized as a rod-shaped, Gram-positive bacterium with a rigid cell wall composed of a thick peptidoglycan called murein, which maintains its shape and withstands high intracellular pressure. It contains a single circular chromosome with one double-stranded DNA molecule. The rod shape of B. subtilis aids in movement through watery environments and facilitates biofilm formation.
Bacillus subtilis is known for its ability to form spores, which allow it to survive harsh conditions such as nutrient deprivation and desiccation. When under stress, B. subtilis can transform into spores and become dormant, a trait that provides a competitive advantage in the soil where long periods of drought and nutrient scarcity are common. Approximately 5% of the B. subtilis genome is dedicated to sporulation and germination processes.
In terms of uses, B. subtilis plays a significant role in research and has potential applications in dietary supplements. It is used in laboratories for studying new treatments for infections and in the health and catering industries for testing cleanliness of surfaces and materials. One of the most promising potential uses of B. subtilis is as an alternative to antimicrobial drugs, given its ability to produce bacteriocins, peptides with antimicrobial activity. These bacteriocins can slow the growth or even destroy colonies of other bacteria types, making B. subtilis a potential treatment against bacterial infections
