“…Results obtained by AAS are presented in Table 4. The lowest values of metals considered toxic (Ak et al, 2021) were Hg 0.001-0.01 µg/g and Cd 0.01-0.06 µg/g. While the higher values for UF were Ni 0.51 µg/g; for SC, Zn 0.96 µg/g; and for GS, Cu 1.48 µg/g.…”

“…Depending on the group, the morphological structure of algae consists of blades, e.g., Ulva genus (Ulvales: Ulvaceae), or thallus, e.g., Sargassum (Fucales: Sargassaceae) and Grateloupia (Halymeniales: Halymeniaceae). Such diversity is related to their chemical composition -determined by geographical and environmental conditions (Ak et al, 2021) -leading to the synthesis of compounds that participate in metabolic pathways: carbohydrates (ulvans, fucans, agarans, or carrageenans), enzymes (involved in photosynthesis; and synthesis of lipids, pigments, and amino acids) and minerals (P, K, Ca, S, Mn, Ni, Cu, Zn) (Harnedy & Fitz-Gerald, 2011;Wahlström et al, 2020).…”

Seaweeds or marine macroalgae are sources of industrial important macro compounds. This work characterizes the chemical composition, morphology, cellular structure, morphometric parameters, protein distribution, density, and quantifies the chemical elements of three seaweed species. The morphological characterization performed by Digital Image Analysis (DIA) showed that the length/width ratio for UF (Ulva fasciata) (15.4/10.9 cm) was greater compared to SC (Sargassum cymosum) and GS (Grateloupia subpectinata) (8.9/7.6 cm and 87/5.3 cm). Using Schiff 's and Coomassie blue reagents, identified carbohydrates and proteins in cells and protein bodies (PB). Cell morphology showed larger cells in the SC cortex (457.8 µm 2 ) and smaller cells in the SC meristoderm (80.5 µm 2 ). PB density (PB/area) and distribution (area occupied by the cell, %) were higher in the cortex of GS (10468 PB/mm 2 , 20%) and lower in the meristoderm of SC (917 PB/mm 2 , 7%). Chemical analysis showed as major compounds: carbohydrates (12-46%), ashes (13-42%), and proteins (6-17%). Meanwhile, the concentration of metals was below the toxicity level. These results contribute to the knowledge of the structure-function relationship of seaweeds metabolites which could be a source of compounds of interest for the industrial sector.

“…Among the alternative foods, seaweed stands out, used in the diet of broilers (Gatrell et al, 2014;Qadri et al, 2019;Petrolli et al, 2019), laying hens (Carrillo et al, 2012), laying quail and cut quail (Cheong et al, 2016;Abouelezz, 2017). The diversity is related to their chemical composition -determined by geographical and environmental conditions (Ak et al, 2021). Algae of the species sargassum sp are abundantly found on the Brazilian coast, have low concentrations of lipids and high concentrations of proteins, polysaccharides, vitamins, and minerals (Carrillo et al, 2012;Fernandes et al, 2020;Hernández-Cruz et al, 2022), and algae have specific antioxidant properties that can help in the metabolic regulation of animals (Gatrell et al, 2014;Boiago et al, 2019;Hajati et al, 2020).…”

Performance, carcass quality and intestinal biometry of feed European quails with seaweed meal (Sargassum sp)

et al. 2023

This work aims to evaluate, at different stages, the productive performance, carcass quality, and intestinal biometry of European quails (Coturnix coturnix Coturnix), consuming diets with increasing levels of seaweed bran (Sargassum sp). A total of 240 European quail chicks (Coturnix coturnix Coturnix) were distributed in a completely randomized design, with four levels of bran inclusion (0.0, 2.5, 5.0, and 7.5%), 6 replications with 10 birds in each experimental plot. In the period from 1 to 21 days, the feed intake of the control group was higher, with lower water consumption. In the period from 22 to 42 days, feed and water consumption increased with the inclusion of seaweed, but with a reduction in weight gain. In the total period, water consumption was higher at the level of 2.5 and 7.5%, with lower consumption in the control group, with a small reduction in slaughter and carcass weight with the inclusion of bran. There was no difference (P > 0.05) in carcass quality and intestinal biometry. We recommended the inclusion of up to 7.5% of sargassum meal in the diet of European quails at all stages, without compromising its productive performance, carcass quality, and intestinal biometry.

Cultivation of Gongolaria barbata (Fucales, Phaeophyceae) with a seaweed-derived biostimulant in order to improve photophysiological fitness and promote fertility to advance the restoration of marine macroalgal forests

et al. 2023

As a result of several anthropogenic factors, Cystoseira sensu lato forests have declined or become regionally extinct in many coastal regions of the Mediterranean. Given the low natural recovery of lost populations, research efforts have been encouraged to develop sustainable and efficient restoration of macroalgal forests on a large scale. By promoting growth and fertility of collected thallus branches under controlled laboratory conditions, the availability of seedlings for restoration could be ensured without jeopardizing natural populations. Here we investigated the effect of a commercial algal biostimulant (AlgatronCifo®) on the photophysiology, growth and fertility of Gongolaria barbata (Stackhouse) Kuntze (Fucales, Phaeophyceae). In a factorial laboratory experiment, two different temperatures (10 ºC and 14 °C) and two culture media [i.e. seawater (SW) and Algatron (AT)] were tested. The photosynthetic performance of G. barbata doubled after three weeks of culture with AT, while it decreased by 25% when cultivated in SW. The highest photosynthetic performance and growth were achieved at 14ºC with AT, where fertile receptacles also developed, followed by seedling settlements. The thalli cultured in AT had similar or better photosynthetic performance than the initial control thalli. AT-cultured thalli had a greater ability to quench energy via photochemical pathways (qP) than those from the SW, which on the contrary, had higher levels of non-photochemical responses (qN, NPQmax). This limited photosynthetic performance was probably linked to the higher P-limitation experienced under that treatment. The algal biostimulant enhanced the physiological performance and induced fertility of G. barbata, demonstrating its valorization potential and setting a new path for improved restoration applications.
