  abstract = {{A}ims {M}acroalgae harbor a rich epiphytic microbiota that plays a crucial role in algal morphogenesis and defense mechanisms. {T}his study aims to isolate epiphytic cultivable microbiota from {U}lva sp. surfaces. {V}arious culture media were employed to evaluate a wide range of cultivable microbiota. {O}ur objective was to assess the antibacterial and biofilm-modulating activities of supernatants from isolated bacteria.{M}ethods and results {S}ixty-nine bacterial isolates from {U}lva sp. were identified based on 16{S} r{RNA} gene sequencing. {T}heir antibacterial activity and biofilm modulation potential were screened against three target marine bacteria: 45%, mostly affiliated with {G}ammaproteobacteria and mainly grown on diluted {R}2{A} medium ({R}2{A}d), showed strong antibacterial activity, while 18% had a significant impact on biofilm modulation. {M}olecular network analysis was carried out on four bioactive bacterial supernatants, revealing new molecules potentially responsible for their activities.{C}onclusion {R}2{A}d offered the greatest diversity and proportion of active isolates. {T}he molecular network approach holds promise for both identifying bacterial isolates based on their molecular production and characterizing antibacterial and biofilm-modulating activities.},
