Bacillus species are known for their versatile antimicrobial properties, have garnered significant attention in the scientific community for their ability to produce a diverse array of antibacterial biomolecules. These biomolecules play a crucial role in combating harmful pathogens and have shown promising potential in various applications, ranging from agriculture to pharmaceuticals. For example, Bacillus subtilis stands out for its production of over 24 antibacterial molecules, showcasing its robust antibacterial capabilities. These molecules exhibit a wide range of antimicrobial activities, making Bacillus subtilis a valuable resource in the fight against pathogenic microorganisms. Antimicrobial biomolecules produced by Bacillus subtilis, such as surfactin and bacilysin, have garnered significant attention for their potent antimicrobial properties and diverse applications. Surfactin, a lipoheptapeptide exhibits strong antibiotic activity against various plant pathogens and pests. Its amphiphilic nature enables it to disrupt cellular membranes, leading to pore formation and cellular damage. On the other hand, bacilysin, a compound with a molecular mass of 270.28 g/mol, is known for its bactericidal activity against both Gram-positive and Gram-negative bacteria. Bacilysin's antimicrobial efficacy stems from its unique structure, including an L-alanine residue at the N- terminus and L-anticapsin at the C-terminus. These biomolecules play a crucial role in biocontrol strategies, inhibiting the growth of phytopathogens and contributing to the biocontrol efficacy of Bacillus species. The diverse biological activities and mechanisms of action of surfactin and bacilysin highlight their potential as key players in the development of novel antimicrobial therapies and biocontrol agents. The research progress on Bacillus subtilis and its antibacterial biomolecules opens up exciting avenues for further exploration. Understanding the mechanisms behind these biomolecules and their interactions with pathogens can pave the way for the development of novel antimicrobial therapies with enhanced efficacy and reduced microbial resistance. In conclusion, Bacillus subtilis emerges as a powerhouse in the realm of antibacterial biomolecules, offering a rich source of diverse antimicrobial agents with the potential to revolutionize the field of antimicrobial research and applications.
