The brown alga Ascophyllum nodosum contains two different vanadium bromoperoxidases.
Haloperoxidases have been detected in a variety of organisms, including bacteria, fungi, algae, and mammals. Mammalian haloperoxidases are known to be directly involved in the oxidative destruction of microorganisms. The algal bromoperoxidases are probably involved in the biosynthesis of bromometabolites, most of which show considerable bactericidal activity. From the brown seaweed Ascophyllum ...
متن کاملBiological activities of fucose-containing polysaccharide ascophyllan isolated from the brown alga Ascophyllum nodosum.
A fucose-containing, sulfated polysaccharide ascophyllan was isolated from the brown alga Ascophyllum nodosum. Composition analysis demonstrated that ascophyllan mainly contains uronic acid, xylose, fucose, and sulfate half ester in approximately equimolecular proportions, which are evidently distinct from those of alginate and fucoidan. Ascophyllan inhibited the proliferation of U937 cells in ...
متن کاملThe Cultivable Surface Microbiota of the Brown Alga Ascophyllum nodosum is Enriched in Macroalgal-Polysaccharide-Degrading Bacteria
Bacteria degrading algal polysaccharides are key players in the global carbon cycle and in algal biomass recycling. Yet the water column, which has been studied largely by metagenomic approaches, is poor in such bacteria and their algal-polysaccharide-degrading enzymes. Even more surprisingly, the few published studies on seaweed-associated microbiomes have revealed low abundances of such bacte...
متن کاملAntidiabetic properties of polysaccharide- and polyphenolic-enriched fractions from the brown seaweed Ascophyllum nodosum.
We screened seaweed species from Atlantic Canada for antidiabetic activity by testing extracts for alpha-glucosidase inhibitory effect and glucose uptake stimulatory activity. An aqueous ethanolic extract of Ascophyllum nodosum was found to be active in both assays, inhibiting rat intestinal alpha-glucosidase (IC50 = 77 microg/mL) and stimulating basal glucose uptake into 3T3-L1 adipocytes duri...
متن کاملLaminarin from Irish Brown Seaweeds Ascophyllum nodosum and Laminaria hyperborea: Ultrasound Assisted Extraction, Characterization and Bioactivity
Ultrasound assisted extraction (UAE), purification, characterization and antioxidant activity of laminarin from Irish brown seaweeds Ascophyllum nodosum and Laminarina hyperborea were investigated. UAE was carried out using 60% ultrasonic power amplitude and 0.1 M hydrochloric acid for 15 min. Separately, solid-liquid extraction was carried in an orbital shaker using 0.1 M hydrochloric acid at ...
