“…Most of them are based on the effects of linear β-1,3 glucans and its induction to the release of H 2 O 2 in tobacco leaves (Klarzynski et al 2000). Jayaraman et al (2011) also point out the extract ability to enhance various defenserelated enzymes including β-1,3 glucanase known to be present in red algae having anti-fungal properties (Cordeiro et al 2006). This combined with the extract's hormone-like elicitor activities (mostly cytokinin-like) was already discussed by Reitz & Trumble (1996) and Khan et al (2009) and the presence of betaines demonstrated by Mackinnon et al (2010) and Blunden et al (2009) in Ascophyllum extracts, reported to influence the increase of chlorophyll content by Whapham et al (1993).…”

Extract powder from the brown alga Ascophyllum nodosum (Linnaeus) Le Jolis (AMPEP): a "vaccine-like" effect on Kappaphycus alvarezii (Doty) Doty ex P.C. Silva Abstract The benefits of using Acadian Marine Plant Extract Powder (AMPEP), obtained from the brown algae Ascophyllum nodosum, for improving growth of the red alga Kappaphycus alvarezii has been demonstrated by authors in the Philippines and Brazil, particularly for increasing daily growth rate and mitigation of epiphytes. However, the processes which occur have not been discussed. This study examined in vitro the relationship between those red algal defense mechanisms and K. alvarezii responses using AMPEP treatments. The administration of the extract reduced the effects of the oxidative burst (production of hydrogen peroxide) which may be extremely aggressive for an individual and its epiphyte. The bleaching of the non-corticated portions of Polysiphonia subtilissima thalli that were cultivated as simulated epiphytes with AMPEP samples confirmed that the reaction was evident in which AMPEP protected K. alvarezii from the hydrogen peroxide effects. It is proposed that the use of the brown seaweed powder AMPEP acts as a potential vaccine, eliciting activation of the red seaweed K. alvarezii natural defenses against pathogens and ameliorating the negative effects of longterm exposure to oxidative bursts.

“…The genus Hypnea is an important source of polysaccharides used as gelling and thickening agents in food and nonfood industries (Andrade et al 2000, Cordeiro et al 2006. In addition to their emulsifying properties, polysaccharides and other metabolites with antibacterial and antitumor properties have been extracted from a number of Hypnea species.…”

“…Furthermore, the aqueous extracts of H. japonica, Hypnea musciformis, and Hypnea cervicornis have shown agglutinating activity against native and trypsin-treated rabbit erythrocytes (Ainouz and Sampaio 1991;Hori et al 1986Hori et al , 2000. Two lectins with antifungal and antimicrobial activity have also been isolated from H. musciformis and H. cervicornis (Melo et al 1997;Nagano et al 2005;Cordeiro et al 2006). It has been reported that the polysaccharide fractions from Hypnea charoides show high antiviral activity against type 1 and type 2 HSV, while maintaining low cytotoxicity levels (Smit 2004).…”

Red algae have been reported to be an important source of polysaccharides with potential immunomodulatory properties. The objective of this study was to characterize the polysaccharides from Halopithys incurva and Hypnea spinella and to evaluate their effect on the synthesis of cytokines by murine cell line RAW 264.7 macrophages. Polysaccharides were obtained by N-cetylpyridinium bromide precipitation and characterized by Fourier transform-infrared spectroscopy. Their effect on the activity of RAW 264.7 macrophages was examined by quantification of tumor necrosis factor (TNF)-α, interleukin (IL)-6, and nitric oxide (NO) production using enzyme-linked immunosorbent assays. The activation of the cytokine IL-6 and NO increased linearly as the concentration of polysaccharides from H. incurva and Hy. spinella increased. In general, the activation of IL-6 and NO was tenfold greater when macrophages were exposed to polysaccharides from H. incurva than when exposed to polysaccharides from Hy. spinella. In contrast, TNF-α concentration did not increase when macrophages were exposed to increasing polysaccharide levels. These results indicate that polysaccharides are strong cytokine IL-6 inducers.

of marine red seaweeds (Jania rubens, Corallina mediterranea and Pterocladia capillacea), J. Taibah Univ. Sci. (2015), http://dx. AbstractSeaweeds are potential renewable resources in the marine environment. The antibacterial activity of Jania rubens, Corallina mediterranea and Pterocladia capillacea were analyzed against human pathogenic bacteria. The present study was performed to investigate the phytochemical constituents of seaweeds, such as alkaloids, flavonoids, steroids, terpenoids and phlobatannins. In this study, we estimated phenols, flavonoids, tannins, pigments and mineral contents and determined the hydrogen peroxide scavenging activity, reducing power and total antioxidant activity of various extracts of selected seaweeds. Phytochemicals were extracted from the three seaweeds using various solvents, such as methanol, ethanol, acetone and chloroform. Among the various extracts, the methanolic extract was found to have the highest reducing power and total antioxidant capacity. We evaluated the seaweeds against Vibrio fluvialis, and Pterocladia capillacea was the most effective at controlling its growth. The highest zone of inhibition was recorded in the methanol extract. The chemical constituents of the seaweeds were characterized by GC-MS, which showed that they contain organic compounds, such as 1,2-benzenedicarboxylic acid.
