MARINE POLLUTION BULLETIN 2024; 203:116435. [PMID: 38772171 DOI: 10.1016/j.marpolbul.2024.116435] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Revised: 04/24/2024] [Accepted: 04/27/2024] [Indexed: 05/23/2024]
Abstract
The Posidonia oceanica (L.) Delile 1813 banquette provides precious ecosystem services for Mediterranean beach nourishment and protection, representing an important way of energy transfer through marine-coastal habitats. It is surprising to note how it is poorly investigated, especially concerning its double role as potential sink and source of chemicals. In particular, few studies exist about the metal (loid)s occurrence and no data are available on emerging contaminants, such as Rare Earth Elements (REEs). The present research investigated for the first time the concentrations of twenty-eight metal(loid)s and fifteen REEs in a well-structured banquette along the Italian coast (Central Tyrrhenian Sea) showing that (i) metal(loid)s and REEs occur in banquettes, with higher relative concentrations of some metal(loid)s (B, Sr, Mn, Fe, Al, Zn) and REEs (Ce, Y, La, Nd) with no statistically significant seasonal variations; (ii) Posidonia banquettes may represent an interesting biological model for chemicals monitoring.

Chemical Composition, Biomolecular Analysis, and Nuclear Magnetic Resonance Spectroscopic Fingerprinting of Posidonia oceanica and Ascophyllum nodosum Extracts. Metabolites 2023; 13:metabo13020170. [PMID: 36837789 PMCID: PMC9963245 DOI: 10.3390/metabo13020170] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 01/17/2023] [Accepted: 01/19/2023] [Indexed: 01/27/2023] Open
Abstract
A detailed analysis of the elemental and molecular composition of Posidonia oceanica (PO) and Ascophyllum nodosum (AN) is presented. In particular, an in-depth study of the molecular identification via NMR spectroscopy of aqueous and organic extracts of PO and AN was carried out, exploiting 2D COSY and pseudo-2D DOSY data to aid in the assignment of peaks in complex 1D proton NMR spectra. Many metabolites were identified, such as carbohydrates, amino acids, organic acids, fatty acids, and polyphenols, with NMR complementing the characterization of the two species by standard elemental analysis, HPLC analysis, and colorimetric testing. For PO, different parts of the live plant (roots, rhizomes, and leaves) were analysed, as well as the residues of the dead plant which typically deposit along the coasts. The combination of the various studies made it possible to recognize bioactive compounds naturally present in the two plant species and, in particular, in the PO residues, opening the door for their possible recycling and use in, for example, fertilizer. Furthermore, NMR is proven to be a powerful tool for the metabolomic study of plant species as it allows for the direct identification of specific biomarkers as well as providing a molecular fingerprint of the plant variety.

Metagenomics Unveils Posidonia oceanica "Banquettes" as a Potential Source of Novel Bioactive Compounds and Carbohydrate Active Enzymes (CAZymes). mSystems 2021; 6:e0086621. [PMID: 34519521 PMCID: PMC8547425 DOI: 10.1128/msystems.00866-21] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Accepted: 08/25/2021] [Indexed: 11/20/2022] Open
Abstract
Posidonia oceanica is a long-living and very slow-growing marine seagrass endemic to the Mediterranean Sea. It produces large amounts of leaf material and rhizomes, which can reach the shore and build important banks known as "banquettes." In recent years, interest in the potential uses of these P. oceanica banquettes has increased, and it was demonstrated that biomass extracts showed antioxidant, antifungal, and antiviral activities. The discovery of new compounds through the culture of microorganisms is limited, and to overcome this limitation, we performed a metagenomic study to investigate the microbial community associated with P. oceanica banquettes. Our results showed that the microbial community associated with P. oceanica banquettes was dominated by Alphaproteobacteria, Gammaproteobacteria, Bacteroidetes, and Cyanobacteria. Pseudoalteromonas was the dominant genus, followed by Alteromonas, Labrenzia, and Aquimarina. The metagenome reads were binned and assembled into 23 nearly complete metagenome-assembled genomes (MAGs), which belonged to new families of Cyanobacteria, Myxococcota, and Granulosicoccaceae and also to the novel genus recently described as Gammaproteobacteria family UBA10353. A comparative analysis with 60 published metagenomes from different environments, including seawater, marine biofilms, soils, corals, sponges, and hydrothermal vents, indicated that banquettes have numbers of natural products and carbohydrate active enzymes (CAZymes) similar to those found for soils and were only surpassed by marine biofilms. New proteins assigned to cellulosome modules and lignocellulose-degrading enzymes were also found. These results unveiled the diverse microbial composition of P. oceanica banquettes and determined that banquettes are a potential source of bioactive compounds and novel enzymes. IMPORTANCE Posidonia oceanica is a long-living and very slow-growing marine seagrass endemic to the Mediterranean Sea that forms large amounts of leaf material and rhizomes, which can reach the shore and build important banks known as "banquettes." These banquettes accumulate on the shore, where they can prevent erosion, although they also cause social concern due to their impact on beach use. Furthermore, Posidonia dry material has been considered a source of traditional remedies in several areas of the Mediterranean, and a few studies have been carried out to explore pharmacological activities of Posidonia extracts. The work presented here provides the first characterization of the microbiome associated with Posidonia banquettes. We carried out a metagenomic analysis together with an in-depth comparison of the banquette metagenome with 60 published metagenomes from different environments. This comparative analysis has unveiled the potential that Posidonia banquettes have for the synthesis of natural products, both in abundance (only surpassed by marine biofilms) and novelty. These products include mainly nonribosomal peptides and carbohydrate active enzymes. Thus, the interest of our work lies in the interest of Posidonia "waste" material as a source of new bioactive compounds and CAZymes.

Abstract
BACKGROUND The marine plant Posidonia oceanica (L.) (PO) has been demonstrated in goats to be a source of fibre. The aim of the present study was to assess the effects of introducing this marine plant as a substitute for barley straw in the feed of mature ewes, assessing the effects of its addition on intake, digestibility and ruminal fermentation and on the ewes' metabolic profiles (energy and protein). PO was used at 75 g day-1 per ewe (15% of the total forage), 150 g day-1 per ewe (30% of the total forage) and 300 g day-1 per ewe (60% of the total forage). RESULTS Substitution of 15% of the forage with PO has no negative consequences on dry matter intake, final live weight and metabolic status in mature ewes; in addition, PO may improve the animal's nitrogen utilisation. The upper limit of substitution was 30%, where only few changes were noted without metabolic consequences. Substitution of 60% impaired performance and affects tissue functions in the animal's body. CONCLUSION Moderate quantities of barley straw (between 75 and 150 g day-1 per ewe) can be replaced by PO in feed rations for mature ewes. © 2017 Society of Chemical Industry.

Abstract
BACKGROUND The marine plant Posidonia oceanica (L.) Delile can be a source of fibre to increase the efficiency of product costs. The aim of the present study was to assess the productive (milk production and performance) and metabolic (blood metabolites) effects of P. oceanica in the ration of dairy goats as a substitute for straw. Posidonia oceanica was used at 225 and 450 g day(-1) per goat in lieu of barley straw. RESULT Supplementation with P. oceanica had no detrimental effects on the body weight, milk production and metabolic status of goats. Goats fed P. oceanica produced more milk fat, had a lower somatic cell count in their milk and showed a decreased risk of oxidative stress. CONCLUSION Goats can be fed P oceanica at levels of up to 450 g day(-1) without detrimental effects on milk production and health, therefore P. oceanica can be a substitute for barley straw in the nutrition of goats.
