Development of Bacillus subtilis cell factories for nutraceuticals production.

Medicinal Plants
Many of the supplements and functional foods on shelves—vitamins, antioxidants, and plant-derived compounds—could soon be brewed in vats of bacteria instead of harvested from overstressed wild plants or energy-intensive chemical plants.
Researchers are reprogramming a harmless, well-studied bacterium found naturally in soil to produce health-boosting compounds that we normally get from plants. Instead of farming huge quantities of herbs or running complicated chemical reactions, we could grow these beneficial substances in a fermentation tank. This approach could ease pressure on wild plant populations and make these compounds cheaper and more widely available.
Key Findings
Bacillus subtilis is considered an ideal microbial host for nutraceutical production due to its GRAS (Generally Recognized As Safe) status and well-understood genetics.
Chemical synthesis and plant extraction of nutraceuticals face significant drawbacks including high costs, low yields, raw material shortages, and environmental pollution.
Synthetic biology tools and advanced metabolic engineering strategies have been systematically applied to construct B. subtilis cell factories for nutraceutical biosynthesis.
chevron_right Technical Summary
Scientists are engineering a common soil bacterium to efficiently produce nutraceuticals—health-promoting compounds normally extracted from plants or made through costly chemical processes. This review outlines the genetic tools and strategies used to turn Bacillus subtilis into a biological factory for these compounds.

Fermentation is an anaerobic metabolic process in which plant cells break down sugars to generate ATP without relying on oxygen, producing byproducts like ethanol, lactate, or organic acids. In plant science, it is essential for understanding how roots and submerged tissues survive low-oxygen
