Antibiotic secretion plays a pivotal role in bacterial interference competition; yet, the impact of environmental hydration conditions on such competition is not well understood. Here, we investigate how affect among bacteria, studying interactions between antibiotic-producing Bacillus velezensis FZB42 and two strains susceptible to its antibiotics: Xanthomonas euvesicatoria 85-10 Pseudomonas syringae DC3000. Our results show that wet-dry cycles significantly modify response bacteria both supernatant cells compared constantly wet conditions. Notably, X. shows increased protection against supernatants B. under cycles, while P. become more cycles. In addition, observed reciprocal interaction velezensis, where inhibits findings highlight important shaping competition, providing valuable insights into microbial ecology water-unsaturated surfaces, with implications for applications as biological control plant pathogens mitigating antibiotic resistance.IMPORTANCEOur study reveals conditions, particularly influence antibiotic-mediated species.
