Insights of species-specific polar lipidome signatures of seaweeds fostering their valorization in the blue bioeconomy

The valorization of seaweeds has generated unprecedented interest in recent years due to their unique chemical characteristics. taxonomic differentiation between Chlorophyta, Rhodophyta, and Ochrophyta is often supported by contrasting Polar lipids are the most abundant class several species labelled as valuable phytochemicals. Nevertheless, little still known about how polar lipidome varies within among different phyla. In this study, six farmed under controlled conditions a land-based integrated multitrophic aquaculture (IMTA), belonging Chlorophyta (Ulva rigida Codium tomentosum), Rhodophyta (Gracilaria gracilis, Palmaria palmata Porphyra dioica), (Fucus vesiculosus) was characterized using state art high-resolution LC-MS analysis. were harvested during same season time window control biotic abiotic shaping lipidome. total, 477 (m/z values) identified distributed over surveyed. Only small group 35 shared all seaweed analyzed study. distribution lipid classes showed trend towards grouping phylum although specie specific signatures can be assigned. Matching data gathered present study with those previously acquired species-specific clustering, which confirm uniqueness these natural biochemical fingerprints. Recognition necessary because assigned important bioactive properties. This knowledge will allow designing new strategies for tuning farming so that yield target compounds improved, living resources fully contribute sustainable growth blue bioeconomy.
