Special Issue Information

Dear Colleagues,

Lipids are major components of marine organisms, as main constituents of cell membranes, as signaling molecules, and as energy sources. Different marine organisms have their specific lipidome, which can be used as biomarkers of trophic chains in marine ecosystems or even to disclose the nutritional value or prospective bioactive compounds. The lipidome of marine organisms is largely unknown, due to the great biochemical diversity and the presence of a large number of different molecular lipid species. The presence of a certain family of lipids can foster the valorization of marine organisms for different applications. However, lipid composition may shift based on species, the origin of organisms, the environment, and the availability of nutrients. Modern lipidomics approaches allow us to overcome this challenge to decode and map the whole lipidome of marine organisms.

This Special Issue of Marine Drugs titled “Lipid Profiling (Lipidome) of Marine Organisms to Foster Biotechnological and Medical Applications” aims to provide a comprehensive lipidomics analysis of a great variety of marine organisms to identify lipid molecular species with added value and health-promoting properties for biotechnological and medical applications, such as nutraceuticals, functional food, or supplements in the food and pharma industries.

As guest editors, we invite colleagues working on marine lipids and their applications to contribute interesting papers to this Special Issue of Marine Drugs with the aim of filling the existing gap in our knowledge of the lipidome of marine organisms.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Marine Drugs is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

In the last decades, the use of algae in biotechnology and food industries has experienced an exponential growth. Codium tomentosum is a green macroalgae with high biotechnological potential, due to its rich lipidome, although few studies have addressed it. This study aimed to investigate the seasonal changes in lipid and pigment profiles of C. tomentosum, as well as to screen its antioxidant activity, in order to evaluate its natural plasticity. Samples of C. tomentosum were collected in two different seasons, early-autumn (September/October) and spring (May), in the Portuguese coast (wild samples), and in a land-based integrated multitrophic aquaculture (IMTA) system (IMTA samples). Total lipid extracts were analysed by LC–MS, GC–MS, and HPLC, and antioxidant activity was screened through free radical scavenging potential against DPPH and 2,20-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radicals. Wild samples showed a high seasonal variability, modifying their lipidome and pigment profiles according to environmental shifts, while IMTA samples showed a relatively stable composition due to early-stage culturing in controlled conditions. The lipids that contributed the most to seasonal discrimination were glycolipids (monogalactosyl diacylglycerol - MGDG and digalactosyl diacylglycerol - DGDG) and the lyso forms of phospholipids and glycolipids. Lipid extracts showed antioxidant activity ranging from 61 ± 2 to 115 ± 35 µmol Trolox g−1 of lipid extract in DPPH assay and from 532 ± 73 to 927 ± 92 µmol Trolox g−1 of lipid extract in ABTS assay, with a more intense antioxidant activity in wild spring samples. This study revealed that wild specimens of C. tomentosum presented a higher plasticity to cope with seasonal environmental changes, adjusting their lipid, pigment, and bioactivity profiles, while IMTA samples, cultured under controlled conditions, displayed more stable lipidome and pigment compositions.
