In this work, the marine cyanobacterial strain <i>Salileptolyngbya</i> sp. LEGE 181209, from Cabo Verde, was systematically characterized to resolve its taxonomy, pigments profile, and cytotoxicity assessment. A polyphasic workflow combining 16S rRNA gene phylogenies, 16S-23S ITS secondary structures, <i>p</i>-distance, morphology, and scanning electron microscopy (SEM) was used to establish the taxonomic placement of the strain as a new species of the genus. PCR assays targeting the toxin biosynthetic genes <i>mcyA</i> and <i>anaC</i>, and cytotoxicity assays in HaCaT keratinocytes showed low-to-absent cytoMarine drugsDescription of a New Marine Cyanobacterium from the Cabo Verde Archipelago: Pigments Profile and Biotechnological Potential of <i>Salileptolyngbya caboverdiana</i> sp. nov.PMC12842673UIDB/04423/2020UIDP/04423/2020Hentschke GSVasconcelos VOliveira FDuarte AJCLopes GfalseDescription of a New Marine Cyanobacterium from the Cabo Verde Archipelago: Pigments Profile and Biotechnological Potential of <i>Salileptolyngbya caboverdiana</i> sp. nov.Cyanobacteria are prolific producers of specialized metabolites of growing interest for blue biotechnology, transversal to various sectors such as cosmetics, foods and pharmaceuticals.
