Four species of marine benthic algae (Laurencia filiformis, L. intricata, Gracilaria domingensis and G. birdiae) that belong to the phylum Rhodophyta were collected in Espírito Santo State, Brazil investigated concerning their biochemical composition (fatty acid, total lipid, soluble proteins, amino acid ash). The content lipid (% dry weight) ranged from 1.1% 6.2%; fatty 0.7% 1.0%; protein 4.6% 18.3%, 6.7% 11.3% ash 22.5% 38.4%. Judging composition, four appear be potential sources dietary...
Background Large or deteriorated skin defects are sometimes life threatening. There is increasing evidence that adult stem cells useful for tissue regeneration. Human mesenchymal (hMSCs) self‐renewing and potent in differentiating into multiple tissues. Objectives To investigate the effects of hMSCs cutaneous wound healing. Methods Wound healing was studied an hMSC‐populated porcine substitute, using a nude rat model to minimize immune reactions. Full‐thickness soft 1·5 × cm size, including...
BACKGROUND: Algae species have been used as an important source of food because they are highly nutritive considering their vitamin, protein, mineral, fiber, essential fatty acid and carbohydrate contents. However, a large number seaweeds poorly studied, especially Brazilian species. Two red macroalgae from the coast (Plocamium brasiliense Ochtodes secundiramea) were assessed with respect to total lipid, acid, nitrogen, amino RESULTS: The lipid contents (dry weight) 36.3 35.4 g kg−1; 9.3...
Abstract An updated synthesis of cyanobacteria and algae information is presented for Brazil aiming to refine the data gathered date evaluate progress biodiversity knowledge about these organisms in country since publication Catálogo de Plantas e Fungos do Brasil. The results 2015 showed an increase 1,250 species (35.7%) when compared 2010, reaching a total 4,747 species. most diverse classes number were Bacillariophyceae, Conjugatophyceae, Florideophyceae, Cyanophyceae, Dinophyceae...
In some coastal areas, large quantities of beach-cast macroalgae can accumulate and are usually considered waste disposed of. However, due to their biofunctional nutritional properties, they have great potential as a new source raw materials. Increasing population growth has made the search for alternative materials with valuable properties urgent; here, could provide potential. Our research goal was characterize profile 12 seaweed species from Brazilian coast assess valorization. A...
Eleven sesquiterpenes (1−11) and one long chain aldehyde (12) have been isolated from the dichloromethane extract of red alga Laurencia scoparia. Four them are new natural products. Scopariol (1) is a product with an unusual rearranged chamigrane-type structure. The other three β-chamigrenes: isorigidol (2), (+)-3-(Z)-bromomethylidene-10β-bromo-β-chamigrene (3), (−)-3-(E)-bromomethylidene-10β-bromo-β-chamigrene (4). in vitro activity compounds 1−12 against parasitant stage Nippostrongylus...
Abstract Currently, five genera are assigned to red seaweeds of the Laurencia complex worldwide: Chondrophycus , s.s. Osmundea Palisada and Yuzurua . The segregated on basis morphological characters, especially reproductive traits, molecular sequences plastid-encoded gene rbc L. Four have been resolved as monophyletic, but not In this study based an L phylogeny we show presence a sixth lineage within complex, viz., marilzae plus two unidentified species from Brazil. phylogenetic position...
Two known sesquiterpenes (1R*,2S*,3R*,5S*,8S*,9R*)-2,3,5,9-tetramethyltricyclo[6.3.0.0(1,5)]undecan-2-ol and (1S*,2S*,3S*,5S*,8S*,9S*)-2,3,5,9-tetramethyltricyclo-[6.3.0.0(1,5)]undecan-2-ol were isolated for the first time from essential oil of red seaweed Laurencia dendroidea collected in Brazilian coast. These compounds not active against eight bacteria strains yeast Candida albicans, but showed some antioxidant activity. Both also found other species showing that they are exclusive...
In Brazil, the Laurencia complex is represented by twenty taxa: s.s. with twelve species, Palisada four species (including Chondrophycus furcatus now that proposal of its transference to in process), and Osmundea Yuzurua two each. The majority Brazilian have been phylogenetically analyzed 54 rbcL sequences, including five other Rhodomelacean as outgroups. analysis showed monophyletic high posterior probability value. was separated into clades, corresponding genera: Chondrophycus, Laurencia,...
Three novel halogenated beta-bisabolene sesquiterpenoids (1-3), together with two know triquinane alcohol sesquiterpenes (6 and 7), were isolated from the red alga Laurencia scoparia their structures elucidated by spectroscopic methods. Single-crystal X-ray crystallography allowed us to confirm structure of 1 as well determine absolute configuration all stereocenters. To best our knowledge, isolation beta-bisabolenes genus has no precedent in literature. Compound showed weak vitro...

Morphological and molecular studies have been performed on Laurencia dendroidea derived from Brazil the Canary Islands. This species possesses all of characters that are typical genus Laurencia, including production first pericentral cell underneath basal trichoblast; tetrasporangia particular cells without formation additional fertile cells; spermatangial branches produced one two laterals suprabasal trichoblasts; a procarp-bearing segment five cells. The phylogenetic position L. was...
Kappaphycus alvarezii is one of the most farmed algae globally. It used almost exclusively for carrageenan industry, although there increasing interest in its biotechnological application as a natural product with biological properties. This cultivated species produces different strains distinct chemical and physiological Despite this, K. has been marketed single biomass. The aim this study was to evaluate differences antioxidant capacities among green, red, brown G11 southeastern Brazil,...

DOI: 10.2216/04-33.1A detailed study vegetative reproductive morphology is provided. The species possesses axial segments, each bearing two periaxial cells, a situation characteristic for genus Chondrophycus. Within Chondrophycus, C....
