Aqueous and organic extracts of twenty-seven species of marine algae (14 species of Rhodophyta, 5 species of Phaeophyta and 8 species of Chlorophyta) collected from the Gulf of Mexico and Caribbean coast of the Yucatan Peninsula (Mexico) were evaluated for their antileishmanial in vitro activity against Leishmania mexicana promastigote forms. The cytotoxicity of these extracts was also assessed...

The complete plastid genome sequence of the red macroalga Grateloupia taiwanensis S.-M.Lin & H.-Y.Liang (Halymeniaceae, Rhodophyta) is presented here. Comprising 191,270 bp, the circular DNA contains 233 protein-coding genes and 29 tRNA sequences. In addition, several genes previously unknown to red algal plastids are present in the genome of G. taiwanensis. The plastid genomes from G. taiwanen...

Siimmiary. BiliproteinS were extracted from representatives of the Cya nophiyta. Rhodophyta, and Crv,ptoplhvta and purified. Both purified and cru(le biliproteins were used to stinmulate rabbit antibody directed specifically against tlle biliproteins. The antigenic and immunogenic inter-relationships of these proteins were investigated bv the Ouclhterlony double diffusion technique. C-ph-cocyan...

A total of 290 florideophyte samples from the Hawaiian Rhodophyta Biodiversity Survey, spanning 17 orders of red algae, were sequenced for the mitochondrial COI DNA barcode, partial nuclear LSU rRNA gene, and plastid UPA rRNA marker. COI was A-T rich (> 60% overall) in comparison to the two rRNA markers, and was also the least conserved, with the third codon position showing the most substituti...

Twelve stream segments were sampled four times in 1998-1999 (one sampling per season) in the drainage basin of the upper São Francisco River (19 masculine 45'-21 masculine 25'S, 49 masculine 05'-51 masculine 30'W), situated in Serra da Canastra National Park, at altitudes ranging from 1,175 to 1,400 m. The macroalgae survey resulted in 30 species, with a predominance of Cyanophyta (12 species =...

Algae taxa are notably diverse regarding pigment diversity and composition, red seaweeds (Rhodophyta) being a valuable source of phycobiliproteins (phycoerythrins, phycocyanin, allophycocyanin), carotenes (carotenoids xanthophylls), chlorophyll a. These pigments have considerable biotechnological potential, which has been translated into several registered patents commercial applications. Howev...

Abstract A lot of data on the flora Barents Sea are scattered in Russian publications and thus largely inaccessible to many researchers. The study aims compile a checklist verify species composition Rhodophyta Sea. is based comprehensive bibliographic referring wide range distribution, from oldest most recent, indispensable for analyzing temporal variability flora. careful revision allows repor...
