A QUESTÃO AMBIENTAL: FLORESTAS E BIODIVERSIDADE
Provedor de dados: 25
Autores: Bertolino, Maria Lúcia.
This work has as objective to argue the environmental question concerning the conservation of the forests and biodiversity. One major issue in this question is that the Brazilian forest sector contributes with an important parcel for the Brazilian economy, generates products for direct consumption or for exportation, generates taxes and jobs for the population and, still, bring positive and negative consequences in the conservation and preservation of both renewable and not renewable natural resources. The forest economy has been, historically, responsible for one of the five largest positive commercial balances of the country and still it supplies 85% of all the products of forest origin found in the national market, therefore, alleviating the pressure on...

Deshidratador solar para productos agrícolas.
Provedor de dados: 32
Autores: Hernández Santana, Crescencio Alejandro.
En México un gran porcentaje de la comercialización de frutas y hortalizas se realiza en fresco. Aunque por un lado, es el tipo de producto preferido por muchos consumidores, por otro, existen excedentes que saturan el mercado, bajan los precios alarmantemente y se incrementan las perdidas. No existe la capacidad instalada en infraestructura para conservar estos productos, aún en fresco. Por lo que este trabajo propone el desarrollo de un deshidratador para productos vegetales, que permitirá alargar su vida de anaquel y transformarlo en otro producto de consumo. La culminación de este proyecto, coadyuvará a mejorar la calidad de vida y arraigo social de los pobladores en regiones de origen. Se hicieron pruebas de secado con el nopal (Opuntia ficus indica),...

Autores: Bertoni,Bianca W.; Telles,Mariana P. de C.; Malosso,Milena G.; Torres,Simone C.Z.; Pereira,José O.; Lourenço,Mirian V.; França,Suzelei de C.; Pereira,Ana M.S.
Jacaranda decurrens (Bignoniaceae) is an endemic species of the Cerrado with validated antitumoral activity. The genetic diversity of six populations of J. decurrens located in the State of São Paulo was determined in this study by using molecular markers for randomly amplified polymorphic DNA (RAPD) and amplified fragment length polymorphism (AFLP). Following optimization of the amplification reaction, 10 selected primers generated 78 reproducible RAPD fragments that were mostly (69.2%) polymorphic. Two hundred and five reproducible AFLP fragments were generated by using four selected primer combinations; 46.3% of these fragments were polymorphic, indicating a considerable level of genetic diversity. Analysis of molecular variance (AMOVA) using these two...

A benthic Si mass balance on the Congo margin: Origin of the 4000 m DSi anomaly and implications for the transfer of Si from land to ocean
Provedor de dados: 5
Autores: Ragueneau, O.; Regaudie-de-gioux, A.; Moriceau, B.; Gallinari, M.; Vangriesheim, Annick; Baurand, F.; Khripounoff, Alexis.
To elucidate the origin of the silicic acid (DSi) anomaly observed along the 4000 isobath on the Congo margin, we have established a benthic Si mass balance and performed direct measurements of biogenic silica (bSiO(2)) dissolution in the deep waters and in the sediments. Results strongly suggest that the anomaly originates from the sediments; the intensity of DSi recycling is consistent with the degradation of organic matter, as observed from Si:O-2 ratios in the benthic fluxes compared to that ratio observed in the anomalies. Strong imbalances, observed in both the Si and C mass balances, suggest that the biogenic matter that degrades and dissolves in these sediments near 4000 m does not come from pelagic sedimentation. It is probably not coming also...

Effects of high pressure on texture and microstructure of sea bass (Dicentrarchus labrax L.) fillets
Provedor de dados: 5
Autores: Cheret, Romuald; Chapleau, Nicolas; Delbarre Ladrat, Christine; Verrez-bagnis, Veronique; De Lamballerie, Marie.
High pressure is an innovative non-thermal food-preservation technology. We studied the effect of high-pressure treatment up-to 500 MPa for 5 min on physical characteristics of sea bass fillets after 0, 7, and 14 d of refrigerated storage.. Color results exhibited an increase of lightness and a slight change of hue, which might be imperceptible in cooked fish. High-pressure treatment induced a decrease of exudation and water-holding capacity Pressure treatment above 300 MPa provoked higher fish hardness after storage than in untreated sample, proving the ability of high pressure to improve textural, quality of chilled, stored fish fillet. These assessments were corroborated with microstructure observations. We showed that high-pressure treatment at 500 MPa...

Sensitivity of clumped isotope temperatures in fossil benthic and planktic foraminifera to diagenetic alteration
Provedor de dados: 5
Autores: Leutert, Thomas J.; Sexton, Philip F.; Tripati, Aradhna; Piasecki, Alison; Ling Ho, Sze; Nele Meckler, A.
Applying the clumped isotope (Δ47) thermometer to foraminifer microfossils offers the potential to significantly improve paleoclimate reconstructions, owing to its insensitivity to the isotopic composition of seawater (unlike traditional oxygen isotope (δ18O) analyses). However, the extent to which primary Δ47 signatures of foraminiferal calcites can be overprinted during diagenesis is not well known. Here, we present Δ47 data as well as high-resolution (∼10 kyr) δ18O and δ13C middle Eocene time series, measured on benthic and planktic foraminifera from ODP/IODP Sites 1408, 1409, 1410, 1050, 1260 and 1263 in the Atlantic Ocean. The sites examined span various oceanographic regimes, including the western tropical to mid-latitude North Atlantic, and the...

Provedor de dados: 5
Autores: Ponis, Emanuele; Parisi, G; Chini Zittelli, G; Lavista, F; Robert, Rene; Tredici, M. R.
The haptophyte Pavlova lutheri was cultivated in a 4-l flat alveolar photobioreactor (FAP) in semi-continuous mode during 35 days, achieving a mean volumetric productivity of 0.4 g l-1 day-1. The microalgal culture was harvested from the photobioreactor at an average concentration of 3.5 g l-1 and subjected to different storage conditions in which the effects of temperature (1 °C, 4 °C and 25 °C), air supply and preservative (ascorbic or propionic acid) addition on the viability of the stored suspensions were investigated. Low temperatures (1 and 4 °C) and air-bubbling extended the shelf-life of the stored suspension, while no beneficial effects of ascorbic or propionic acid were found. The influence of temperature and air-bubbling on fatty acid content...

Freezing and chemical preservatives alter the stable isotope values of carbon and nitrogen of the Asiatic clam (Corbicula fluminea)
Provedor de dados: 5
Autores: Syvaeranta, Jari; Martino, Aurelia; Kopp, Dorothee; Cereghino, Regis; Santoul, Frederic.
We tested the impacts of most common sample preservation methods used for aquatic sample materials on the stable isotope ratios of carbon and nitrogen in clams, a typical baseline indicator organism for many aquatic food web studies utilising stable isotope analysis (SIA). In addition to common chemical preservatives ethanol and formalin, we also assessed the potential impacts of freezing on delta C-13 and delta N-15 values and compared the preserved samples against freshly dried and analysed samples. All preservation methods, including freezing, had significant impacts on delta C-13 and delta N-15 values and the effects in general were greater on the carbon isotope values (1.3-2.2aEuro degrees difference) than on the nitrogen isotope values (0.9-1.0aEuro...

An Improved Protocol for Flow Cytometry Analysis of Phytoplankton Cultures and Natural Samples
Provedor de dados: 5
Autores: Marie, Dominique; Rigaut-jalabert, Fabienne; Vaulot, Daniel.
Preservation of cells, choice of fixative, storage, and thawing conditions are recurrent issues for the analysis of phytoplankton by flow cytometry. We examined the effects of addition of the surfactant Pluronic F68 to glutaraldehyde-fixed photosynthetic organisms in cultures and natural samples. In particular, we examined cell losses and modifications of side scatter (a proxy of cell size) and fluorescence of natural pigments. We found that different marine phytoplankton species react differently to the action of Pluronic F68. In particular, photosynthetic prokaryotes are less sensitive than eukaryotes. Observed cell losses may result from cell lysis or from cell adhesion to the walls of plastic tubes that are commonly used for flow cytometry analysis....

Freeze-dried Spermatozoa and Freeze-dried Sperm Injection into Oocytes
Provedor de dados: 19
Autores: SUZUKI, Hiroshi; 鈴木, 宏志.
Attempts to freeze-dry spermatozoa are not new. Successful conception and full-term development using freeze-dried spermatozoa were reported in the cow and rabbit prior to 1960. However, these preliminary results have not been confirmed. Spermatozoa become defective in motility after freeze-drying and are unable to fertilize eggs both in vivo and in vitro. However, in 1998, freeze-drying of mammalian spermatozoa was demonstrated without loss of genetic or reproductive potential. Freeze-dried spermatozoa support normal development when injected directly into oocytes by means of an intracytoplasmic sperm injection (ICSI) technique. Recent investigations of freeze-dried sperm have focused on the factors affecting freeze-drying in spermatozoa in an effort to...

Autores: Telis,Vânia Regina Nicoletti; Romanelli,Pedro Fernando; Gabas,Ana Lúcia; Telis-Romero,Javier.
The legal Pantanal caiman (Caiman crocodilus yacare) farming, in Brazil, has been stimulated and among meat preservation techniques the salting process is a relatively simple and low-cost method. The objective of this work was to study the sodium chloride diffusion kinetics in farmed caiman muscle during salting. Limited volumes of brine were employed, with salting essays carried at 3, 4 and 5 brine/muscle ratios, at 15%, 20% and 25% w/w brine concentrations, and brine temperatures of 10, 15 and 20ºC. The analytical solution of second Fick's law considering one-dimensional diffusion through an infinite slab in contact with a well-stirred solution of limited volume was used to calculate effective salt diffusion coefficients and to predict the sodium...

Land Preservation in British Columbia: An Empirical Analysis of the Factors Underlying Public Support and Willingness to Pay
Provedor de dados: 31
Autores: Androkovich,   Robert A.; Desjardins,   Ivan; Tarzwell,   Gordon; Tsogaris,   Peter.
This study extends previous empirical research on land preservation by considering an actual land preservation scheme, the agricultural land reserve in British Columbia, Canada. The reserve was established in 1973 to ensure that development did not occur on the province’s most productive agricultural land. ‘To ensure that local food production is maintained,’ ‘the economic importance of British Columbia’s agricultural sector,’ and ‘to protect the environment’ are the most important factors that underlie support for the reserve. Aggregate, provincewide willingness to pay to maintain the land reserve is substantial, with our most conservative estimate being Can$91.18 million per year.

Evaluation of glycerin as preserving agent of chicken serum for plate agglutination test
Provedor de dados: 89
Autores: Freitas,ES de; Soldá,A; Calegari,DL; Munaretto,FC; Dietrich,GF; Back,A.
Serum is widely used for the purpose of monitoring and diagnosis support for most of poultry diseases. In the case of the serum plate agglutination test (SPA), commonly used to detect antibodies for Salmonella Pullorum (SP), Mycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS), serum cannot be frozen because it may result in false positive. Without freezing, serum can last only for a few days. In this experiment, glycerin was evaluated as a serum preservering agent. About 50 samples for each disease and analyzed by SPA test previously were separated. Glycerin was added to serum from commercial chickens, with and without antibodies for SP, MG and MS, in the proportion of 1:1 (serum:glycerin) and kept at refrigerated conditions (2 to 8 ºC). For four...

ABSTRACT The dual-stage sugar substitution technique (D3S) was used to induce sugar replacement in mango. It involved two stages, in which high-calorie sugars were partially removed from the fruit samples in the first stage and, in the second one, low-calorie sugar was incorporated into the mango. Ultrasonic waves can be applied in one or both stages and their use was also evaluated in this study. Results showed that submitting samples to ultrasonic waves (25 kHz) in both stages and their immersion in Stevia-based solution (250 or 500 g kg-1) in the second stage for 10, 20 and 30 min of processing gave higher water loss during the process, while greater solids gain could be achieved by applying ultrasound only in the first stage.

Autores: Nuvoloni,Felipe M.; Feres,Reinaldo J. F.; Demite,Peterson R.
Mites associated to Xylopia aromatica (Lam.) Mart. (Annonaceae) in urban and rural fragments of semidecidual forest. Native plants can shelter a great diversity of mites. Notwithstanding, the conservation of the forest fragments where the plants are located can influence the structure of the mites community. Generally, in homogenous environments the diversity is lower due to the dominance of one or a few species. In this work, we studied the mite community on Xylopia aromatica (Lam.) Mart. (Annonaceae) in two fragments of semidecidual forest: one on rural and other on urban area. Seven individuals of X. aromatica were monthly sampled from April 2007 to March 2008, in each of these fragments. Descriptive indexes of diversity, dominance and evenness were...

ABSTRACT Minced fish can be used in the preparation of fish products, despite being very susceptible to lipid oxidation and microbial growth. Fish snacks are widely appreciated in Asian countries, but still little studied in Brazil. Thus, the aim of this study was to produce snacks containing 20, 30, and 40% minced fish of Nile tilapia filleting waste and evaluate their stability at time zero and throughout 15, 30, and 45 days of storage at room temperature (25 ºC) by physicochemical, microbiological, and sensory characterization. The inclusion of minced fish decreased (P &lt;0.05) the volatile nitrogenous base levels (0.71 to 0.56 mg N.100g-1) and increased pH (5.45 to 5.90) of the snacks. An increase (P &lt;0.05) in lipid oxidation (1.10 to 2.03 mg....

ABSTRACT Buriti (Mauritia flexuosa L.f), a palm tree native to South America and widely distributed in Brazil, displays significant ecological, economic and biotechnological importance. However, the disorderly extractivism and environmental degradation of its endemic areas are leading to reductions in, and/or extinction of the buriti palm tree, causing ecological imbalance with significant economic losses for rural communities and genetic diversity. Consequently, populational genetic diversity studies have become relevant as a strategy for conserving the species. Therefore, this study evaluated the genetic structure of 10 populations from the Lençóis Maranhenses region, in the state of Maranhão, Brazil, using microsatellite markers. Results indicated that...

Provedor de dados: 42
Autores: Barreto,Cintia F.; Vilela,Claudia G.; Baptista-Neto,José A.; Barth,Ortrud M.
Aiming to investigate the deposition of pollen grains and spores in Guanabara Bay, Rio de Janeiro State, 61 surface sediment samples were analyzed. The results showed that the current deposition of palynomorphs in surface sediments of Guanabara Bay represents the regional vegetation of this hydrographic basin. The differential distribution of palynomorphs followed a pattern influenced by bathymetry, tidal currents speed, discharge of numerous rivers, and by human activity. The dominance of representatives of Field Vegetation reflects the changes of the original flora caused by intense human activities in the region. The continued presence and richness of pollen types of rain forest in the samples indicates that their source area might be the vegetation...

Effect of lactic acid bacteria on extention of shelf life and growth of Listeria monocytogenes in beef steaks stored in CO2- rich atmosphere
Provedor de dados: 58
Autores: Djenane,Djamel; Martínez,Luis; Blanco,Domingo; Yangüela,Javier; Beltrán,José A.; Roncalés,Pedro.
Beef steaks were inoculated with one or other of two protective strains of lactic acid bacteria (bacteriocinogenic Lactobacillus sakei CTC 372 or the uncharacterized Lactobacillus CTC 711), and stored under modified atmospheres (20-40% CO2). Inoculation of meat with LAB inhibited growth of the spoilage bacteria. Neither CO2 in the pack atmosphere or inoculation with protective strains, nor a combination of both, affected formation of metmyoglobin or the development of off-odours. The formation of metmyoglobin in meat pigments and the sensory odour scores were compatible to those of fresh meat which had not undergone either oxidative deterioration or microbial spoilage. Listeria monocytogenes was inhibited in broth by meat surface microbiota containing the...

Autores: Linde,Giani Andrea; Luciani,Alana; Lopes,Ana Daniela; Valle,Juliana Silveira do; Colauto,Nelson Barros.
Abstract Basidiomycetes have several biotechnological and industrial applications such as enzyme production, bioremediation, pharmaceutical and functional food production. Due to climatic features, the preservation of several basidiomycetes is threatened, and to guarantee the preservation of this genetic resource, the development of long-term preservation techniques is necessary once there is no universal protocol for the cryopreservation of basidiomycetes. Cryopreservation is a technique in which microorganisms are submitted to ultralow temperatures. Therefore, this study aimed to collect information on the main conditions for long-term cryopreservation of basidiomycetes in the last 20 years. Scientific articles on cryopreservation of basidiomycetes...

Autores: Lagos,Maria Jeannine Bonilla; Sobral,Paulo José do Amaral.
ABSTRACT: Edible chitosan-based films, in pure form (CH100), or blended with gelatin (GEL50:CH50), with and without boldo extract (B) were prepared. The oxygen permeability of the films, as well as color changes and antioxidant and antimicrobial activities on beef hamburgers samples were evaluated. CH100+B film exhibited optimal oxygen barrier properties (6.40±0.170cc-mL/[m²-day]), and this value was significantly increased in blended films (GEL50:CH50+B = 12.99±1.50cc-mL/[m²-day]) (P&lt;0.05). All films provoked color changes in hamburger samples during storage, and the samples covered with CH100+B film showed a lower brightness and a higher redness. All films effectively protected beef hamburger from lipid oxidation, and boldo extract incorporation in...

Orchid cryopreservation
Provedor de dados: 64
Autores: Vendrame,Wagner; Faria,Ricardo Tadeu de; Sorace,Mauren; Sahyun,Sandra Aparecida.
Orchids are lush and highly valuable plants due to their diversity and the beauty of their flowers, which increases their commercialization. The family Orchidaceae comprises approximately 35,000 species, distributed among more than 1,000 distinct genera and 100,000 hybrids, totaling approximately 8% to 10% of all flowering plants. With the advance of agriculture and the constant destruction of their natural habitat, orchid species are collected in an indiscriminate manner by collectors and vendors, and this extractive activity threatens many species with extinction, drastically reducing their genetic variability in nature. Therefore, it is essential to seek alternatives that make the preservation of such species feasible using techniques with low...
