 The seaweeds are bio-resource rich in sulfated and neutral polysaccharides. The tropical seaweed species used in this study (Solieria filiformis), after dried, shows 65.8% (w/w) carbohydrate, 9.6% (w/w) protein, 1.7% (w/w) lipid, 7.0% (w/w) moisture and 15.9% (w/w) ash. The dried seaweed was easily hydrolyzed under mild conditions (0.5 M sulfuric acid, 20 min.), generating fermentable monosaccharides with a maximum hydrolysis efficiency of 63.21%. Galactose and glucose present in the hydrolyzed were simultaneously fermented by Saccharomyces cerevisiae when the yeast was acclimated to galactose and cultivated in broth containing only galactose. The kinetic parameters of the fermentation of the seaweed hydrolyzed were Y(P⁄S) = 0.48 ± 0.02 g.g−1, PP = 0.27 ± 0.04 g.L−1.h−1, h = 94.1%, representing a 41% increase in bioethanol productivity. Therefore, S. filiformis was a promising renewable resource of polysaccharides easily hydrolyzed, generating a broth rich in fermentable monosaccharides for ethanol production.

Esta nota é a primeira contribuição para a distribuição especial das algas marinhas do litoral paranaense (Caiobá). São considerados três tipos de litoral: a) Litoral rochoso sujeito à ação de arrebentação. b) Litoral rochoso mais ou menos abrigado. c) Manguesais. Dentro do esquema proposto, o primeiro tipo é subdividido em 2 zonas: 1.º) Zona dos borrifos, situada acima do limite médio da maré alta (fig. 2 n.º 1), correspondente à "Splash zone" ou à "Sprit zone" dos autores estrangeiros. 2.º) Zona de arrebentação (Ressaca), situada entre os níveis médios das marés baixa e alta, correspondendo à "Interdital zone" ou à "Gezeitenzone" dos autores estrangeiros, (fig. 2 n.º 2). A primeira zona só conta com uma alga, Lyngbya confervoides e pelo menos mais duas espécies de moluscos do gênero Littorina. A segunda zona, a mais rica tanto em algas como em animais, é essencialmente caracterizada em Caiobá pelas algas seguintes: Levringia sp. Chaetomorpha media e Centroceras clavulatum na parte mais alta, associadas a balanoides (craca) e a Mytilus perna (marisco). Mais abaixo domina Pterosiphonia pennata, Hypnea musciformis e Bryocladia thyrsigera. São apresentados também mais três tipos secundários dependendo das condições locais dos rochedos. Esta sucessão de Littorina, Balanus e Mytilus é a mesma existente no sul da África, segundo se depreende dos trabalhos de Stephenson (11,12) e de vários de seus colaboradores. O segundo tipo apresenta também duas zonas, sendo a segunda a mais rica e variada, aparecendo aqui como dominante, uma associação na qual, Callithamnion, Laurencia papulosa, Gigartina Teedii e Sargassum cymosum são as mais abundantes. É sugerida a existência de uma zona abaixo do limite inferior das marés baixas, zona essa representada por Rhodymenia Palmetta, Plocamium brasiliensis e Spatoglossum Schroederi pelo menos. É feita uma rápida enumeração das algas dos manguesais.

Anticoagulant and antithrombotic properties of sulfated-polysaccharides (SP) from marine algae are extensively exploited. However, reports on the vascular effects of SP from red algae are rare in the literature. The polysaccharide from Solieria filiformis (Sf-SP) was isolated by ion exchange chromatography, analyzed by agarose gel electrophoresis and tested in male Wistar rats. The inflammation studies were performed using the paw-edema model and the relaxant activity in isolated aorta precontracted with phenylephrine. The anticoagulant effect was evaluated by the test of partial thromboplastin activation time. The SP (1 mg/kg) was not antiinflammatory, but induced acute edema with maximal activity at 30 min (0.35 ± 0.04 mL) compared to controls (0.05 ± 0.03 mL). Cumulative addition of Sf-SP in phenylephrine-contracted tissues produced relaxation with maximal inhibition of 69% (IC50 29.3 ± 9.0 μg/mL) at 300 μg/mL in comparison to controls (0.51 ± 0.09 g). Sf-SP also extended human plasma coagulation time by 2.1 times. These substances could be used as important tools for the study of vascular alterations.

A complete account on the shallow-water Pycnogonida known up to now from depths between 0-30 m in the Caribbean Sea of Colombia is presented. Almost all the information included herein is based upon the data obtained by the first author during a 14-month fieldwork programme carried out at the Instituto de Investigaciones Marinas de Punta de Betin (INVEMAR) in Santa Marta, Magdalena department.        5312 specimens of 50 species, including 7 species new to science in the genera Ammothella (2), Tanystylum (1), Callipallene (2), Anoplodactylus (1) and Endeis (1), were collected from 179 samples at 45 stations. The area covered by this research ranges in the west from Punta Brava, just near the airport of Santa Marta, eastward to Punta el Diamante at the eastern border of the Tayrona National Park, extending over about 70 km of coastline. Additionally, 6 other pycnogonid species reported previously from outside this area, which are also known from the Caribbean Sea of Colombia are briefly reviewed.        The species from the Santa Marta area are described in detail, with comments on their intraspecific affinities, habitat preference, phenology, vertical distribution and geographic distribution.        Quantitative samples were taken approximately monthly at three stations at Bahía Concha over one year to compare the species composition from substrata of different structure, namely stands of the brown algae Digenia simplex and Sargassum cymosum on a dead Porites reef, and a stand of Thalassia testudinum, which was interspersed with dead coral substratum and coralline algae.        Number of species at all of these stations was found to be similar and species composition of the two species of brown algae almost identical. Achelia sawayai was by far the most numerous species in samples of Digenia simplex, whereas Tanystylum acuminatum and T. isabellae were most numerous in Sargassum cymosum. Species composition in Thalassia was rather different from that of the algal vegetation. In Thalassia, Ammothella appendiculata and A. exornata were the commonest species which were not found in Digenia and Sargassum.        No evidence was found that reproduction of pycnogonids in this tropical area is limited to certain periods of the year. One might presume a shorter reproductive cycle only for Tanystylum acuminatum, because ovigerous males appeared at the end of the rainy season in December and remained until May, therefore for most of the duration of the dry season.        Generally, number of species and specimens collected at all three quantitative sampling stations was rather variable from month to month, implying a heterogenous distribution within the substratum, which surely depend on the distribution of their food.        Zoogeographic patterns are at present almost impossible to interpret, owing to the limited information available on the distribution of most species. However, it can be seen that the Santa Marta region has a very high number of shallow-water pycnogonid species, compared with the fauna of Panamá and Belize, where only 34 and 33 species have been recorded, respectively. However, the high number of species found in the Santa Marta area may be a result of the extensive collecting efforts made over a period of more than one year.
