Bacillus subtilis

Bacillus subtilis is a type of bacteria commonly found in soil and the gut of some animals, including humans. It's a gram-positive, rod-shaped bacterium that can form spores, allowing it to survive in harsh environments. B. subtilis is known for its role in various applications, such as fermentation in food production (like in some soy sauces) and as a model organism in scientific research. It is generally considered harmless and even beneficial, contributing to soil health and plant growth, and is also explored for its potential in probiotic and industrial applications.
