*As a model organism, ''B. subtilis'' is commonly used in laboratory studies directed at discovering the fundamental properties and characteristics of Gram-positive spore-forming bacteria. In particular, the basic principles and mechanisms underlying formation of the durable endospore have been deduced from studies of spore formation in ''B. subtilis''.
* Its surface-binding properties play a role in safe radionuclide waste [e.g. thorium (IV) and plutonium (IV)] disposal.
* Due to its excellent fermentation properties, with high product yields (20 to 25 gram per litre) it is used to produce various enzymes, such as [[amylase]] and proteases.
*''B. subtilis'' is used as a [[soil inoculant]] in [[horticulture]] and [[agriculture]].
* It may provide some benefit to [[saffron]] growers by speeding corm growth and increasing stigma biomass yield.
* It is used as an "indicator organism" during gas sterilization procedures, to ensure a sterilization cycle has completed successfully. Specifically ''B. subtilis'' endospores are used to verify that a cycle has reached spore-destroying conditions.
* ''B. subtilis'' has been found to act as a useful bioproduct fungicide that prevents the growth of ''[[Monilinia]] vaccinii-corymbosi'', a.k.a. the mummy berry fungus, without interfering with pollination or fruit qualities.
*Both metabolically active and non-metabolically active ''B. subtilis'' cells have been shown to reduce gold (III) to gold (I) and gold (0) when oxygen is present. This biotic reduction plays a role in gold cycling in geological systems and could potentially be used to recover solid gold from said systems.
