The amount of data collected previously for Velloziaceae neither clarified relationships within the family nor helped determine an appropriate classification, which has led to huge discordance among treatment by different authors. To achieve acceptable phylogenetic result and understand evolution roles characters in supporting groups, a total evidence analysis was developed included approx. 20 % species all recognized genera sections Velloziaceae, plus outgroups representatives related...
Chlorophyll a and carotenoids are important pigments in photosynthesis. Several studies have been published describing extraction analysis protocols of these pigments, mainly vascular plant species. This study standardizes an protocol substances Gracilaria tenuistipitata var. liui, red seaweed. Apical portions grown vitro were triturated liquid nitrogen. Extracts prepared 1.5 mL solvent centrifuged. Quantitative qualitative analyses performed by UV/visible light spectrophotometry high...
Objective: The main objective of this article is to diagnose the state-of-the-art technology for hydrogen (H2) production from algae assess competitiveness in renewable fuels market. Theoretical Framework: Actions decarbonize energy matrix are part Kyoto Protocol and Paris Agreement control climate change, without negatively impacting security. H2 has become one competitive sources decarbonization actions ways increase global temperature. Algae potential due their rapid growth, metabolic...

Algal polysaccharides exhibit a wide range of biological activities and potential applications. Many these bioactivities correlate positively with the presence sulfate groups on polysaccharides. The most common method used for quantification in algal samples is turbidimetric using barium chloride-gelatin reagent. However, original procedure difficult to adapt routine analysis since it laborious time-consuming. An optimized was established 96-well microplates, advantage reducing waste...
In vitro culture of the mutualistic fungus leaf-cutting ants is troublesome due to its low growth rate, which leads storage problems and contaminants accumulation. This paper aims at comparing radial rate Atta sexdens rubropilosa Forel in two different media (Pagnocca B MEA LP). Although total LP was greater all along bioassay, no significant difference detected between efficiencies media. Previous evidences for this were confirmed. Since these data cannot point efficiency one medium over...
Leaf epicuticular waxes are the interface between leaves and atmosphere, acting in reduction of water loss. Therefore, we believe this part cuticle influences species ecophysiological responses under different rainfall conditions. In study, investigated how leaf wax (EW) Aspidosperma pyrifolium contributes to desiccation reduction, its impacts on gas exchanges. We selected a site preserved tropical seasonally dry forest, analysed both intact (control) that had EW removed mechanically...
Antioxidants protect cells from the injuries caused by oxidative reactive species, especially under biotic and abiotic stressful conditions. Each kind of free radical presents different sites and, therefore, assays could be done to better evaluate antioxidant capacity a compound. Little is known about secondary metabolites Annona coriacea Mart. (Annonaceae), related their capacity. Eleven flavonols were isolated leaves: Quercetin-3-O-gentiobioside (1), Quercetin-3-O-robinobioside (2), Rutin...
Saplings of Psidium guajava (guava, Myrtaceae), a tropical tree species, were exposed to industrial air pollutants at Cubatâo, the largest complex Latin America, along two periods, each one comprising one-year: period I, July/2000 – June/2001; II, December/2000 November/2001. in experimental sites: Pilões River Valley (PV), reference site, with low contamination by pollutants; and Mogi (MV), site severely affected from chemical, fertilizer, ceramic, iron steel industries. At both sites, main...
Croton macrobothrys Baill, Euphorbiaceae, is a tree from the Atlantic Forest in Southern Brazil, used traditional medicine and popularly known as "dragon's blood" "pau-sangue". Leaf n-hexane, dichloromethane methanol extracts were analyzed by GC/MS evaluated for their vitro antiproliferative activity on cell lines 786-0 (kidney), HT-29 (colon), K562 (leukemia), NCI-ADR/RES (drug resistant ovary), NCI-H460 (lung), MCF-7 (mammary), PC-3 (prostate), OVCAR-3 (ovary), U251 (glioma) UACC-62...
