The main goal of this study was to assess the bioactive and polysaccharide compositions, along with the antioxidant and antibacterial potentials, of five seaweeds collected from the northeastern coast of Algeria. Through Fourier transform infrared spectroscopy analysis and X-ray fluorescence spectroscopy, the study investigated the elemental composition of these seaweeds and their chemical structure. In addition, this study compared and identified the biochemical makeup of the collected seaweed by using cutting-edge methods like tandem mass spectrometry and ultra-high-performance liquid chromatography, and it searched for new sources of nutritionally valuable compounds. According to the study’s findings, Sargassum muticum contains the highest levels of extractable bioactive compounds, showing a phenolic compound content of 235.67 ± 1.13 µg GAE·mg−1 and a total sugar content of 46.43 ± 0.12% DW. Both S. muticum and Dictyota dichotoma have high concentrations of good polyphenols, such as vanillin and chrysin. Another characteristic that sets brown algae apart is their composition. It showed that Cladophora laetevirens has an extracted bioactive compound content of 12.07% and a high capacity to scavenge ABTS+ radicals with a value of 78.65 ± 0.96 µg·mL−1, indicating high antioxidant activity. In terms of antibacterial activity, S. muticum seaweed showed excellent growth inhibition. In conclusion, all five species of seaweed under investigation exhibited unique strengths, highlighting the variety of advantageous characteristics of these seaweeds, especially S. muticum.

The purpose of the research was to study the effect of the quercetin-Ferrum complex on the synthesis of plastid pigments and secondary metabolites in berry crops. In the research, biotechnological, physiological, biochemical and statistical methods were used. The ability of quercetin, which is one of the most common flavonol aglycons, to create a chelated complex with Fe 2+ and regulate physiological processes associated with oxidation-reduction reactions, synthesis of pigments and metal enzymes when being a supplement of nutrient medium is shown. With the addition of quercetin-Ferrum complex with a fraction of Fe 2+ in a concentration equivalent to the base nutrient media composition optimized for the cultivation of berry crops in vitro, regenerated plants showed a sufficiently high regeneration capacity. Based on the indicators of the content of chlorophylls and carotenoids in leaves, the physiological availability of Ferrum in the quercetin-Ferrum complex was established. The concentration of chlorophylls a and b in raspberry and strawberry leaves increased by 20−25%, and the content of carotenoids increased by 30−40%. On the contrary, in black currant, the content of chlorophyll a in leaves decreased by 18−20% and chlorophyll b by almost 75%. It was found that quercetin is a biologically active phenolic chelating agent capable of chemically binding Fe 2+ ions and participating in the regulation of growth processes, in particular in the induction of callusogenesis. Metal-flavonol complex is advisable to use in micro clonal reproduction of plants sensitive to oxidative stress in conditions of Fe 2+ ions deficiency under the condition of individual selection of the components of the chelate complex and adjusting its concentration in the nutrient medium.

“…In another study, the extraction of Cladophora glomerata using acetone, methanol, and ethanol solvents was investigated, and various glomerata hydrogels were developed using GCMS analysis and subsequent extracts. The study emphasized that this hydrogel could potentially be developed as a skin care product [34]. In another study, polyamidoamine-based hydrogels containing photoactive chlorophyll a obtained from Spirulina seaweed extract were developed for potential applications in photodynamic therapy [35].…”

This study was aimed to create a bioactive hydrogel form with PVA/PVP (polyvinyl alcohol/poly(N-vinylpyrrolidone) polymer using acetone and ethanol extractions of Janiarubens red algae and investigate some pharmaceutical properties. The anti-candidal activity and some inhibition performance of J. rubens/PVA/PVP hydrogel were investigated on Candida tropicalis which is one of the important causes of bloodstream infections. The physicochemical properties of J. rubens/PVA/PVP hydrogel were revealed using FTIR and swelling-absorption tests. The volatile compounds of J. rubens extracts were examined by GCMS. By mixing the extracts in equal proportions, PVA/PVP-based hydrogel was prepared. According to the results, Cumulative Drug Release was stable at 25 °C for the first 5 h. The IZ (inhibition zone) and MIC (minimum inhibitory concentration) of J. rubens/PVA/PVP hydrogel were 9.01 mm and 80.20 mg/mL, respectively. It was found that logarithmic reduction and percent reduction were seen as 1.5 CFU/mL and 97.5%, respectively, on C. tropicalis exposed to J. rubens/PVA/PVP hydrogel in the first 5 min of the incubation. After exposure of C. tropicalis to J. rubens/PVA/PVP, the number of viable cells transferred from the gel to water was between 76.1 and 73.1% in high glucose medium, while it was between 92.2 and 80.8% for the PVA/PVP hydrogel under the same conditions. As a result, PVA/PVP hydrogel was made bioactive with J. rubens extracts for the first time in this study, and its potential for use as a functional anticandidal hydrogel on C.tropicalis has been demonstrated.
