Pseudopeptides of Marine Vibrio spp. from Taiwan and Their Combined Treatment Effects with Commercial Antibiotics.

strains, identified by 16S rDNA, were isolated from the marine environment surrounding Taiwan, revealing diverse bioactive effects, such as iron-chelating and antimicrobial activities. Notably, the hierarchical clustering dendrogram of mass spectrum profiles of the strains using matrix-assisted laser desorption ionization time-of-flight, in contrast to the phylogenetic tree based on 16S rDNA sequencing analysis, exhibited a strong correlation with their observed bioactivities. Within this set, global natural products social molecular network analysis by LC-HRMS/MS highlighted that three strains, DJW05 - 1, DJW05 - 8, and DJW21 - 4, shared similar bioactive pseudopeptides in the same cluster.
