Abstract
The use of microorganisms in environmental biotreatment is gaining attention, particularly Bacillus subtilis (B. subtilis), recognized for its effectiveness in wastewater treatment and soil remediation. Its success stems from its diverse biological activities and adaptability, which improve environmental quality and ecological balance. This paper reviews the remediation capabilities and mechanisms of B. subtilis, focusing on its applications in water purification and soil pollution management. B. subtilis facilitates pollutant degradation and adsorption through enzyme production, organic acids, unique cell wall properties, and interactions with other microorganisms. The article addresses current challenges and future directions, emphasizing the need for enhanced cultivation, screening, and genetic engineering of functional strains. Understanding the interactions of these strains with other microorganisms and studying their ecological and toxicological impacts are essential for optimizing microbial remediation, providing both theoretical and practical foundations for bioremediation efforts.
