“…Furthermore, Ulva spp. are used in land-based tank or pond systems for bio-remediation of dissolved waste from animal aquaculture (Shpigel et al 1993;Bolton et al 2009), and they are proposed as biofilters in eutrophic (nutrient rich) marine ecosystems (Cohen and Neori 1991;Areco et al 2021).…”

Applications of seaweeds require the supply of uniform biomass, yet performance of Ulva is generally characterised by a wide variation across study sites and seasons, as well as among species or strains. This study aimed to determine the variation in growth, biochemical composition and nutrient uptake of five Ulva strains collected in the Eastern Scheldt estuary (the Netherlands) and cultivated under standardised outdoor conditions from July to November. Surprisingly, only two strains performed well (maximum 291 ± 95 and 570 ± 122 kg FW ha−1 day−1 for VEE and YER strain), one strain showed slow growth (maximum 155 ± 91 kg FW ha−1 day−1 for SCH strain), and the last two strains (JAC and KOM) did not grow at all. Chemical composition was only determined for the well-performing strains. For most of the parameters, strong seasonality was observed; growth, crude fat (0.4–1.3%), ash (16–25%) and starch (3–11%) decreased, whereas fibres (37–45%) and proteins (7–22% crude; 6–18% true) increased. To evaluate the bio-remediation potential, nutrient uptake of YER, VEE and SCH strains was determined from in- and outflowing water (453–2027 µmol DIN; 4–101 µmol PO4 kg FW h−1). Highest rates were observed for the SCH strain which was not in accordance with growth nor composition, suggesting that nutrients were not (all) directed towards vegetative growth. This study demonstrates a large variation in performance between different Ulva strains collected in relatively close proximity and thereby highlights the importance to test a variety of local seaweed strains prior to commercial farming.

“…Being at the base of marine ecosystems, macroalgae are responsible for up to 50% of the global oxygen production and are a food and habitat source for numerous marine organisms (Areco, Salomone and Afonso, 2021). Found in the most various regions, from tropical to polar climates, the green macroalga Ulva lactuca can grow up to 30 cm wide, attached, sessile or free-floating and is known to form floating communities called green tides (Dominguez and Loret, 2019;Raj, Anandan and Mathew, 2020;Areco, Salomone and Afonso, 2021). Additionally, these macroalgae are used as compost or as an enriching agent in agriculture, as a food source in aquaculture, whereas its by-products (e.g.…”

“…From an environmental perspective, U. lactuca has been harnessed for biomonitoring Duarte et al, 2021a) and bioremediation of heavy metals (Trinelli, Areco and Dos Santos Afonso, 2013;Trinelli et al, 2019). Its cosmopolitan distribution, fast growth rates and tolerance to abiotic stresses, such as salinity (Bews et al, 2021) and heavy metals (Bonanno, Veneziano and Piccione, 2020;Areco, Salomone and Afonso, 2021), make this species an exceptional model in ecotoxicological studies.…”

Emerging pollutants impose a high degree of stress on marine ecosystems, compromising valuable resources, the planet and human health. Pharmaceutical residues often reach marine ecosystems, and their input is directly related to human activities. Fluoxetine is an antidepressant, and one of the most prescribed selective serotonin reuptake inhibitors globally and has been detected in aquatic ecosystems in concentrations up to 40 μg L−1. The present study aims to evaluate the impact of fluoxetine ecotoxicity on the photochemistry, energy metabolism and enzyme activity of Ulva lactuca exposed to environmentally relevant concentrations (0.3, 0.6, 20, 40, and 80 μg L−1). Exogenous fluoxetine exposure induced negative impacts on U. lactuca photochemistry, namely on photosystem II antennae grouping and energy fluxes. These impacts included increased oxidative stress and elevated enzymatic activity of ascorbate peroxidase and glutathione reductase. Lipid content increased and the altered levels of key fatty acids such as hexadecadienoic (C16:2) and linoleic (C18:2) acids revealed strong correlations with fluoxetine concentrations tested. Multivariate analyses reinforced the oxidative stress and chlorophyll a fluorescence-derived traits as efficient biomarkers for future toxicology studies.

“…According to scientific studies, marine algae, also known as seaweeds, have high pollutant binding capacities because their cell walls contain polysaccharides, proteins, or lipids that contain functional groups such as amino, hydroxyl, and sulphate, that can serve as binding sites for pollutants.Ulva lactuca, green macroalgae called green sea lettuce or green laver usually found in coastal areas, it has been widely studied for its ability to accumulate pollutants, as a bioindicator, and as a remediation agent (Areco et al, 2021).…”

The present study evaluates the efficiency of microalgae Chlorella vulgaris and Ulva lactuca for removing fenamiphos, imidacloprid and oxamyl from water. The influence of pH, incubation time, insecticide and biomass concentration on the degradation of insecticides were considered valuable factors in the study. The biosorption experiments were performed by adding 100, 500, and 900 mg/L of alga to the insecticide aqueous solution (50, 250, and 450 mg/L). The experiments were performed at different pHs; 5, 7, and 9 with a time course; of 5, 10, and 15 min. UV-Vis spectrophotometric method was conducted for quantifying insecticides. The optimum conditions from the Plackett-Burman test were obtained at 15 min, pH 5, 50 mg/L insecticide concentration, and 900 mg/L biomass that exhibited a removal percentage of 66.20 % and 61.91% for fenamiphos with C. vulgaris and U. lactuca, respectively, While, 5 min, pH 9, 50 mg/L pesticide concentration and 900 mg/L algae biomass with the removal of 40.76, 28.44% and 70.28-70.07 % of imidacloprid and oxamyl for C. vulgaris and U. lactuca, respectively. This study proved that the removal of insecticides by fresh water and marine microalgae C. vulgaris and U. lactuca is both effective and biomass of algae dependent. Thus, C. vulgaris and U. lactuca showed a potential reduction of insecticides in polluted water samples. This study will open new channels for a more indepth understanding of how to remove the insecticide pollutants in the aquatic environment based on microalgae technology.
