13. Cell wall, lignin and fatty acid-related transcriptome in soybean: achieving gene expression patterns for bioenergy legume
Increasing efforts to preserve environmental resources have included the development of more efficient technologies to produce energy from renewable sources such as plant biomass, notably through biofuels and cellulosic residues. The relevance of the soybean industry is due mostly to oil and protein production which, although interdependent, results from coo

14. Characterization of açaí (E. oleracea) fruits and its processing residues.
The aim of this work was to study the source of the açaí residue for its possible commercial applications by characterizing the fruit (fresh and dry mass), and performing an anatomic study of the pericarp from which were identified the origin of the anthocyanins, and fatty acids, and fibers; also the vascular system, its fibers constituents and fibrils wer

15. Teores de B-Caroteno e A-tocoferol presentes na microalga Spirulina (Arthrospira) Platensis cultivada com diferentes fotoperÃodos / Levels of B-carotene and-tocopherol present in the Spirulina (Arthrospira) grown in different photoperiods Platensis
The microalga cyanophyceae Spirulina platensis has been commercialized and studied due to its high nutritional value. It has shown to be a rich source of a great variety of vitamins, minerals, proteins, polyunsaturated fatty acids, carotenoids, phycobilins, and polysaccharides that exhibit potential therapeutic properties. The aim of the present work was to

17. Extrato de bagaço de uva como antioxidante natural em carne de frango processada e armazenada sob congelamento / Grape pomace extract as natural antioxidant in processed chicken meat stored under freezing
Chicken meat, due to the high concentration of unsaturated fatty acids, is highly susceptible to lipid oxidation, which affects taste, aroma, colour and texture of foods, limiting its stability and shelf-life. Due to the possible toxicity of synthetic antioxidants and the current demand for healthier products, the use of natural antioxidants, such as grape s

18. Matéria orgânica de Latossolos Húmicos: análises térmica e espectroscópica, efeito do uso e correção química / Organic matter of humic Latosol (Oxisol): thermal and spectroscopic analyses, land use and chemical correction
The objective of this study was to contribute to the clarification of several aspects related to the behavior of organic matter (OM) in highly weathered tropical soils. Six samples of humic A horizon Latosol were collected from three sites in Minas Gerais: i) Sericita, (under coffee crop, pasture, ferns and Atlantic Forest fragment); ii) Mutum (under Atlanti

19. Estudo fitoquímico de espécies de Araceae de São Paulo / Phytochemical study of São Paulo Araceae species
The present work describes isolation and identification or structural elucidation of secondary metabolites from the Ieaves and roots or tubers of Araceae species which were collected in the Pinciguaba Reserve, São Paulo State, Brazil. The extraction of plant materiaIs with hexane, ethanoI, water-ethanol, yielded its respective extracts. The composition of f

20. Clonagem e caracterização do gene da enzima Δ6-dessaturase de ácido graxo e análise de parte do genoma funcional de Thalassiosira fluviatilis
Omega 3 polyunsaturated fatty acids are molecules found in oils that are of fundamental importance in the maintenance of human health, that need to be consumed by the humans. Special attention is given to the omega 3 long chain polyunsaturated fatty acids (LCPUFAs), like eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) due to their influence in the

21. Arqueologia biomolecular: passos preliminares para interpretações sobre a origem dos resíduos orgânicos preservados em fragmentos de cerâmica pré-colonial no Brasil
Organic residue analysis of archaeological potsherds is a well-established method for determining the uses of European and North American pottery vessels. In the present work we assess if the organic residues identified in Brazilian potsherd extracts are related to commodity processes (e.g. cooking or surface treatment) or to other non-archaeological sources

22. Testes rapidos (kits) para avaliação da qualidade de oleos, gorduras e produtos que os contenham e sua correlação com os metodos oficiais da AOCS. / Rapids tests (Kits) which serve for quality evaliation of oils, fats and products containin them and this correlatin which AOCS officials methods.
The DiaMed Food Analysis Test System (F.A.T.S.) consists of rapid tests which serve as alternatives for conventional methods in the determination of free fatty acids (%FFA), peroxide value (PV), and the concentration of alkenal (p-anisidine test) and malonaldehyde (TBA test). These tests can be employed in the evaluation of oils, fats and products containing

24. A contribuição da quimica para o estudo de Orchidaceae e seus polinizadores
The investigation of the Orchidaceae pollination is the aim of this work. At first the floral fragrance of five species were studied: Stanhopea lietzeii, Stanhopea insignis, Polystachya estrellensis, Psilochilus modestus and Epidendrum secundum. The fragrances of these species are mixtures of monoterpenoids, sesquiterpenoids, and aromatic compounds and fatty
