Bacillus Subtilis File

: Spores are even used in developing self-healing concrete , where they germinate to fill cracks with calcium carbonate precipitation [8, 16].

Bacillus subtilis , commonly known as the , is a highly resilient, Gram-positive bacterium renowned for its ability to form protective endospores that survive extreme heat, radiation, and desiccation [2, 5, 29]. It is a versatile "workhorse" in biotechnology, valued for its efficient protein secretion system and its role as a safe probiotic for gut health [18, 22, 25]. Key Biological Features bacillus subtilis

: The cells are highly motile, utilizing peritrichous flagella (tails covering the entire surface) to move through liquids [2, 5]. : Spores are even used in developing self-healing

: Formulated into dietary supplements for humans and additives for livestock to improve digestion, immune function, and gut microbiome balance [4, 8, 31, 34]. Key Biological Features : The cells are highly

: While historically seen as an obligate aerobe, it is a facultative anaerobe that can grow without oxygen through fermentation [1, 2, 9].

: It is a rod-shaped bacterium, typically 2–6 µm long and about 1 µm in diameter [1, 2].

: Acts as a "cell factory" to mass-produce enzymes (like amylase and protease for laundry detergents) and vitamins, specifically Riboflavin (B2) [1, 7, 8].
