The intensive use and misuse of antibiotics over the last decades have generated a strong selective pressure for the emergence of multi-resistant strains and nosocomial infections. Biofilm has been demonstrated as a key parameter in spreading infections, especially in hospitals and healthcare units. Therefore, the development of novel anti-biofilm drugs is actually of the upmost importance. Here, the antimicrobial and antibiofilm activities toward pathogenic microorganisms of a set of non-ribosomal synthesized peptides and polyketides isolated from Bacillus amyloliquefaciens ANT1 culture supernatant are presented.
Keywords: Antibiofilm activity; Bacillus amyloliquefaciens; NRPS; PKS.
