Surfactin-type components produced by Bacillus species are cyclic lipopeptides with broad potential across environmental sustainability, agriculture, and environmental protection. In addition to their ecological relevance, these compounds also exhibit practical bioactivities such as antibacterial, antifungal, antiviral, and antitumor properties. In this study, we successfully performed the taxonomic identification of 40 Bacillus strains isolated from fungal compost. The surfactin production by each strain, as well as the individual surfactin variants, was examined by High-Resolution Mass Spectrometry (HRMS). Of the 40 Bacillus strains, 18 were found to produce surfactins, representing members of the species B. subtilis, B. halotolerans, B. licheniformis, and B. velezensis. A total of 109 distinct surfactin variants were identified among the isolates. Following the spectrometric analysis, biological assessments were performed to determine the antimicrobial activity of the surfactin producing strains against phitopathogenic bacteria and fungi. B. subtilis strains were generally effective against phytopathogenic bacteria. For phytopathogenic fungi, B. halotolerans strains demonstrated the strongest activity. In general, our findings on the production of surfactin by Bacillus isolates provide a solid foundation for the identification of promising candidates for future biocontrol applications.
