“…It is endemic to Japan, Korea, and China, and has been introduced in the French Mediterranean, the European Atlantic, New Zealand, Australia, Argentina, and Italy (Hay and Luckens 1987;Sanderson 1990;Fletcher and Manfredi 1995;Casas and Piriz 1996;Wallentinus 1999;Cecere et al 2000;Aguilar-Rosas et al 2004). In Russia, U. pinnatifida is only found in Peter the Great Bay (Sea of Japan; see Skriptsova et al 2004).…”

Crude fucoidan was extracted from the brown alga Undaria pinnatifida collected monthly from April to last July in Peter the Great Bay (Japan Sea, Russia). The amount of crude fucoidan rose markedly from April to June-July (from 3.2 to 16.0% dry weight) as the plant matures. An analysis of the monosaccharide composition of the fucoidan extracted showed that the alga synthesized polysaccharides with various structures which were dependent on the algae age. In juvenile plants collected in AprilMay, this was represented by sulfated manno-galactofucan containing up to 19-28 mol% of mannose and about 20 mol% of galactose, whereas in matured plants collected in June-July, the polysaccharide was represented by a sulfated galactofucan containing more than 38 mol% galactose. It is postulated that the production of sori causes a subsequent effect on fucoidan synthesis and leads to an enhanced of crude fucoidan content and an increased molar concentration of galactose. Crude fucoidan content in sporophylls increased 5 times, and galactose content in this polysaccharide rose s1.6 times with sori formation. The structural characteristics of the fucoidan extracted from sporophylls of Undaria collected in July were also studied. The fractionation of crude fucoidan on DEAE-Sephadex A-25 gave two fractions, F1 and F2 in equal quantities. F1 was characterized as manno-galactofucan sulfate and F2 was galactofucan sulfate. The molecular weights of both fractions were in a range of 30-80 kDa. Analysis of fucoidan structure using ESI-FTICR mass spectrometry showed the presence of mixed oligosaccharides consisting of fucose and galactose. Presumably, the polysaccharide molecules contain blocks built up of successively linked residues of fucose and galactose. These blocks are built from two to five or more residues of monosaccharides. According to IR-spectroscopy data, the main portion of sulfates is located at C2; in addition, sulfate esters are also present at C4 on the fucose and C3 and C6 of the galactose units.

“…En las costas del Pacífi-co, de donde proviene, se ha extendido tanto por las costas de Nueva Zelanda (Hay & Luckens, 1987), Australia (Campbell & Burridge, 1998) y Tasmania (Sanderson, 1990), como más recientemente por las del noroeste de EE.UU. (Silva & al., 2002) y México (Aguilar-Rosas & al., 2004). En la Península Ibérica fue detectada su presencia por primera vez en la costa atlántica de Galicia en 1988 (Cremades, 1995) y en el mar Cantábrico de Asturias en 1995 (Salinas & al., 1996).…”

ResumenUndaria pinnatifida es una especie asiática de gran interés económico como alga alimentaria que en la década de los ochenta apareció por primera vez en España en las costas de Galicia, donde actualmente se encuentra ampliamente distribuida y naturalizada. Las poblaciones intermareales de los esporófitos de esta especie en la costa gallega son propias de localidades moderadamente expuestas a la acción del oleaje, siendo muy notorias a principios de primavera; aunque pueden encontrarse casi todo el año, al existir al menos dos períodos anuales de reclutamiento. La morfología de los ejemplares que las forman es muy variable y está fuertemente relacionada con las variaciones espaciotemporales de las condiciones ambientales. Analizando la cronología de su introducción en Galicia y los hábitats y tipos de comunidades en las que se integra, se observa claramente la influencia de las actividades humanas en todo ello, sobre todo las derivadas de la acuicultura de moluscos y el tráfico marítimo. U. pinnatifida es una especie de lenta expansión natural, poco agresiva y que ocupa temporalmente nichos ecológicos vacíos, siendo solo abundante sobre sustratos artificiales o en aquellos naturales cuya vegetación ha sido en alguna medida previamente degradada.Palabras clave: Atlántico noroeste, algas marinas, especies alóctonas, Undaria pinnatifida, morfología, fenología, ecología, impacto ambiental. AbstractUndaria pinnatifida is an Asian seaweed that is valuable as an edible species. This kelp was first reported for Spain in the 1980s on Galician coasts, where it is now widely distributed and incorporated into the native community. In Galicia, intertidal populations of the sporophytic phase typically inhabit sites under moderate wave-exposure in the early spring, albeit they can be found throughout the year as the species displays at least two recruitment periods per year. The morphology varies between individuals and depends strongly on the spatiotemporal pattern of environmental conditions. The chronology of the introduction of this species and the types of habitat where it is currently integrated on Galician coasts clearly reveal that the presence and local expansion of this kelp is influenced largely by human activities, mainly shellfish aquaculture and maritime traffic. U. pinnatifida has a slow natural expansion, limited aggressiveness and it temporarily fills empty niches; this kelp displays luxuriant growth only on artificial substrates or in otherwise disturbed communities.

“…This seaweed is an abundant, culturable marine plant found along temperate coastal regions of the northwestern Pacific Rim, including Korea, Japan, and China. It also occurs in temperate regions worldwide as an invasive species (Aguilar-Rosas et al, 2004). Hence, the U. pinnatifida rhizoid is a promising alternative source of AA because of its huge biomass, potential for waste utilization, and its high AA content.…”

The non-utilized biomass of the aquacultured seaweed Undaria pinnatifida, particularly the rhizoid, is an alternative source of arachidonic acid (AA). Of the five aquacultured kelps that were tested, U. pinnatifida yielded the highest amount of AA, which was isolated from the rhizoids. Its identity (C20:4 n-6) was confirmed from gas chromatography-mass spectrometry spectral data. The optimal conditions for post-harvest storage or pretreatment of the rhizoids in Provasoli's enriched seawater for AA extraction were determined to be pH 7.8, 2% CO 2 -enriched air, 20 μmol m -2 s -1 light, and 10°C. Under these conditions, the AA content after 1 day of storage was enhanced by up to 127%. In the absence of light under ambient aeration, the AA content after 1 day of storage diminished to 90%. Rhizoids collected late in the season (April and May) contained the highest amounts of AA (approximately 2.5 mg/g tissue).
