In this work, the marine cyanobacterial strain Salileptolyngbya 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\u201323S ITS secondary structures, p-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 mcyA and anaC, and cytotoxicity assays in HaCaT keratinocytes showed low-to-absent cytotoxicity, supporting a safety-forward profile for downstream use. A sequential extraction with solvents of different polarities yielded complementary pigment fractions profiled by HPLC-PDA and spectrophotometry. Total carotenoids reached 72.7 \u00b5g mg\u22121 of dry extract (DE), the profile being dominated by \u03b2-carotene and zeaxanthin (\u224842 and 8 \u00b5g mg\u22121 of DE, respectively); chlorophyll-a was also very representative, reaching 85.6 \u00b5g mg\u22121 of DE. Phycobiliproteins dominated the polar fraction, with phycocyanin reaching 150 \u00b5g mg\u22121, followed by sugars (19.7 \u00b5g of glucose equivalents mg\u22121) and phenols (8.8 \u00b5g of gallic acid equivalents mg\u22121).<\/jats:p>","DOI":"10.3390\/md24010029","type":"journal-article","created":{"date-parts":[[2026,1,8]],"date-time":"2026-01-08T10:10:50Z","timestamp":1767867050000},"page":"29","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Description of a New Marine Cyanobacterium from the Cabo Verde Archipelago: Pigments Profile and Biotechnological Potential of Salileptolyngbya caboverdiana sp. nov."],"prefix":"10.3390","volume":"24","author":[{"given":"Aimone Jussiene Cardoso","family":"Duarte","sequence":"first","affiliation":[{"name":"CIIMAR\/CIMAR LA, Interdisciplinary Centre of Marine and Environmental Research, University of Porto, Terminal de Cruzeiros do Porto de Leix\u00f5es, Av.
