Morphology: Rod-shaped cells measuring approximately 4–10 micrometers in length and 0.25–1.0 micrometers in diameter.
Endospore Formation: Capable of producing tough, protective endospores that allow survival under harsh conditions.
Motility: Possesses multiple flagella, facilitating rapid movement in liquid environments.
Metabolism: Considered a facultative anaerobe, capable of surviving with or without oxygen.
Bacillus subtilis, commonly known as the hay bacillus or grass bacillus, is a Gram-positive, catalase-positive bacterium found in soil and the gastrointestinal tract of various organisms, including humans. This rod-shaped, flagellated bacterium is notable for its ability to form endospores, enabling it to survive extreme environmental conditions. B. subtilis has been extensively studied as a model organism in microbiology, particularly in the areas of bacterial chromosome replication and cell differentiation. It is also recognized for its industrial applications, especially in the production of enzymes used in various biotechnological processes.
Applications:
Biotechnology: Utilized for the industrial-scale production of enzymes and other metabolites.
Research: Serves as a model organism for studying bacterial genetics, cell differentiation, and sporulation processes.
