“…The seagrass Halophila stipulacea (Forsskål) Ascherson was collected from Marina Cap Monastir (Southern Mediterranean Sea) and immediately brought to the laboratory in plastic bags containing seawater to prevent dehydration of the plants. The seagrass was identified by Dr. Rym Zakhama Sraieb (High Institute of Biotechnology of Sidi Thabet) [4,39]. The collected specimens were washed thoroughly with tap water to remove all the extraneous matter such as epiphyte, sand particles, pebbles, and shells.…”

The Marine Seagrass Halophila stipulacea as a Source of Bioactive Metabolites against Obesity and Biofouling

et al. 2020

Marine organisms, including seagrasses, are important sources of biologically active molecules for the treatment of human diseases. In this study, organic extracts of the marine seagrass Halophila stipulacea obtained by different polarities from leaves (L) and stems (S) (hexane [HL, HS], ethyl acetate [EL, ES], and methanol [ML, MS]) were tested for different bioactivities. The screening comprehended the cytotoxicity activity against cancer cell lines grown as a monolayer culture or as multicellular spheroids (cancer), glucose uptake in cells (diabetes), reduction of lipid content in fatty acid-overloaded liver cells (steatosis), and lipid-reducing activity in zebrafish larvae (obesity), as well as the antifouling activity against marine bacteria (microfouling) and mussel larval settlement (macrofouling). HL, EL, HS, and ES extracts showed statistically significant cytotoxicity against cancer cell lines. The extracts did not have any significant effect on glucose uptake and on the reduction of lipids in liver cells. The EL and ML extracts reduced neutral lipid contents on the larvae of zebrafish with EC50 values of 2.2 µg/mL for EL and 1.2 µg/mL for ML. For the antifouling activity, the HS and ML extracts showed a significant inhibitory effect (p < 0.05) against the settlement of Mytilus galloprovincialis plantigrade larvae. The metabolite profiling using HR-LC-MS/MS and GNPS (The Global Natural Product Social Molecular Networking) analyses identified a variety of known primary and secondary metabolites in the extracts, along with some unreported molecules. Various compounds were detected with known activities on cancer (polyphenols: Luteolin, apeginin, matairesinol), on metabolic diseases (polyphenols: cirsimarin, spiraeoside, 2,4-dihydroxyheptadec-16-ynyl acetate; amino acids: N-acetyl-L-tyrosine), or on antifouling (fatty acids: 13-decosenamide; cinnamic acids: 3-hydroxy-4-methoxycinnamic acid, alpha-cyano-4-hydroxycinnamic), which could be, in part, responsible for the observed bioactivities. In summary, this study revealed that Halophila stipulacea is a rich source of metabolites with promising activities against obesity and biofouling and suggests that this seagrass could be useful for drug discovery in the future.

“…turbinata-uvifera from Lebanon, Egypt, Syria, Cyprus, and the South Levantine coast (for details see Verlaque et al, 2015). The species was first reported as C. chemnitzia from Algeria in 2015 based on S. Lamouti's personal communication (Verlaque et al, 2015); from Tunisia in 2016 (Sghaier et al, 2016) and Lebanon (Bitar et al, 2017). Caulerpa chemnitzia is typically considered as a non-aggressive component of the Lessepsian flora (Verlaque et al, 2000).…”

This paper is a collection of novel distributional records of 20 species belonging to 8 phyla (Chlorophyta, Rhodophyta, Cnidaria, Ctenophora, Annelida, Mollusca, Arthropoda and Chordata) from 11 Mediterranean countries, namely, Spain: an additional record of the Canary dentex Dentex canariensis is reported from Spain (Valencia), this is the northernmost record of this species in the Mediterranean; Algeria: the first documented record of Caulerpa chemnitzia is reported from the Algerian coast; France: the first record of the Spotted sea hare Aplysia dactylomela is reported from the eastern coast of Corsica; Italy: the first records of the Lessepsian polychaete Dorvillea similis and the alien bivalve Isognomon legumen are reported from Italian waters while additional records of Mnemiopsis leidyi in the south Adriatic are provided; Libya: the first record of an alien mollusc Crepidula fornicata is reported from Libyan waters; Malta: multiple sightings of gelatinous species Apolemia uvaria, Phacellophora camtschatica and Physophora hydrostatica are reported for the first time from Maltese waters, as well as the first tentative record of the Orange-spotted grouper Epinephelus cfr. coioides; Greece: an occurrence of a rare Bigeye thresher shark Alopias superciliosus is reported from Hellenic Ionian waters, while the first records of the alien Mertens’ prawn-goby Vanderhorstia mertensi, the recently described cyclopoid copepod Oithona davisae and the alien red seaweed Asparagopsis armata are reported from the Aegean Sea. The presence of the micromollusc Euthymella colzumensis is confirmed for Greece; Cyprus: the first record of the red cornetfish Fistularia petimba is reported from Cyprus; Turkey: the first record of the alien jellyfish Marivagia stellata is reported from south-eastern Turkey; Israel: the first records of the sea nettle Chrysaora sp. in the Levant are reported.

Fate of two invasive or potentially invasive alien seaweeds in a central Mediterranean transitional water system: failure and success

et al. 2016

View full text Add to dashboard Cite

Over the past 15 years, populations of two invasiveor potentially invasive alien seaweeds have beenstudied by means of both quantitative and qualitativemethods in the Mar Piccolo basin in Taranto (SouthernItaly, Mediterranean Sea). The dynamics of the cold-temperatebrown seaweed Undaria pinnatifida (Alariaceae,Laminariales) showed a boom-and-bust path, ending inapparent local extinction. In contrast, the tropical redseaweed Hypnea cornuta (Cystocloniaceae, Gigartinales)has shown a steadily invasive path since its introduction.The respective failure and success of these marine alienspecies were analysed in relation to their biological andecological traits and the environmental characteristics ofthe Mar Piccolo in comparison with other Mediterraneancoastal lagoons. The study confirms that temperature andsalinity monitoring in the recipient region could providea first estimation of the invasive potential of an alien speciessoon after its introduction
