Bacillus Subtilis Info

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

: The cells are highly motile, utilizing peritrichous flagella (tails covering the entire surface) to move through liquids [2, 5]. bacillus subtilis

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 : While historically seen as an obligate aerobe,

: Under stress or nutrient starvation, it undergoes asymmetric cell division to create an endospore . These spores can remain dormant for years and are resistant to environmental extremes like UV radiation and high temperatures [1, 2, 5]. It is a versatile "workhorse" in biotechnology, valued

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