Brominating activity of the seaweed Ascophyllum nodosum: impact on the biosphere

Environmental Science & Technology, 1991
(...) We report that the brown seaweeds Laminaria saccharina, Laminaria digitata, Fucus vesiculosis, Pelvetia canaliculata, and Ascophyllum nodosum and the red seaweeds Chondrus crispus and Plocamium hamatum contain bromoperoxidases. The intact plants are able to brominate exogeneous organic compounds when H 2 O 2 and Br − are added to seawater ...

Ultrasound, microwave and enzyme-assisted multiproduct biorefinery of Ascophyllum nodosum

Food Chemistry
This study investigated the multiproduct (fucoidans, β-glucans, proteins, carotenoids, fatty acids, amino acids and polyphenols) valorization of the invasive macroalgae Ascophyllum nodosum within a green biorefinery concept using ultrasound (US), microwave (MW) treatment followed by supercritical CO2 (SC-CO2) with co-solvent and enzymatic extraction ...

Structural features of a novel glucuronogalactofucan from ascophyllum nodosum

Carbohydrate Research, 1978
Abstract Extraction of the brown alga Ascophyllum nodosum with water (adjusted to pH 2) yielded several fucose-containing polymer fractions 1 . One of these fractions was further purified by repeated fractional precipitation with ethanol from aqueous calcium chloride solutions. The resulting, electrophoretically (cellulose acetate) pure polymer was

THE EFFECT OF SEAWEED (ASCOPHYLLUM NODOSUM) EXTRACT ON YIELD AND QUALITY CRITERIA IN PEPPERS

Acta Horticulturae, 1995
Three different treatments of seaweed extract (Ascophyllum nodosum) were applied at five different stages of growth, as foliar applications, to examine their effects on yield and quality criteria in peppers (cv. California Wonder) Each treatment caused an increase in fruit yield, and a 10-day earlier first harvest was observed in treatment groups (trt ...

A Demographic Study of Two Populations of the Seaweed Ascophyllum Nodosum

Ecology, 1992
Very little is known about the demography in size—structured seaweed populations, and this is especially true for populations in variable environments. Thus, the demography of the brown alga Ascophyllum nodosum was analyzed with a matrix population model.

Detection of technetium-99 in Ascophyllum nodosum from around the Welsh coast

Chemosphere, 2006
The presence of the radionuclide (99)Tc in the marine environment is of concern to environmental scientists because of its conservative nature and high concentration factor in commercially valuable species. The brown seaweed Ascophyllum nodosum (Linnaeus) Le Jolis was used to biomonitor the spatial distribution of (99)Tc around the Welsh coast, an area

Effect of the seaweed Ascophyllum nodosum on lambs during forced walking and transport

Journal of Animal Science, 2007
The objective of this study was to determine the effect of feeding Ascophyllum nodosum (ANOD) to lambs at 0 (control), 0.5, 1, or 2% of DMI/d for 2 wk on lamb physiology in response to forced walking and transport during hot weather. Forty-four lambs (26 kg +/- 4.3) were used, and each lamb swallowed 3 gelatin capsules filled with ANOD or their normal ...

Extraction and characterization of protein from Irish brown seaweed Ascophyllum nodosum

Food Research International, 2017
This study investigates traditional and non-conventional methods of extraction of protein from Irish brown seaweed A. nodosum. Acid, alkali, combined acid-alkali with and without ultrasound pretreatment were investigated for extraction of protein from A. nodosum.

The Effect of the Ascophyllum nodosum Extract Goëmar GA 14 on the Growth of Spinach

Botanica Marina, 1992
The seaweed extract Goemar GA 14 (2.5 g L −1 ), when applied as a foliar spray to two varieties of Spinacia oleracea L., 4 and 6 weeks after sowing, increased the total fresh matter production of the leaves by 12 to 15 %, after 8 weeks of culture. However the O 2 evolution rate of chloroplasts from plants treated with seaweed extract did not exhibit a

Molecular cloning, structure, and reactivity of the second bromoperoxidase from Ascophyllum nodosum

Bioorganic Chemistry, 2012
The sequence of bromoperoxidase II from the brown alga Ascophyllum nodosum was determined from a full length cloned cDNA, obtained from a tandem mass spectrometry RT-PCR-approach. The clone encodes a protein composed of 641 amino-acids, which provides a mature 67.4 kDa-bromoperoxidase II-protein (620 amino-acids).
