Impact of Brown Ring Disease on the energy budget of the Manila clam Ruditapes philippinarum
Provedor de dados: 5
Autores: Flye Sainte Marie, Jonathan; Pouvreau, Stephane; Paillard, Christine; Jean, Fred.
Brown Ring Disease (BRD) is a bacterial disease caused by the pathogen, Vibrio tapetis. The disease induces formation of a brown deposit on inner shell of the Manila clam, Ruditapes philippinarum. Development of this disease is correlated with a decrease in the condition index of infected clams. Experiments were conduced in order to assess the effect of the development of BRD on two parameters affecting the energy balance of the clams: the clearance and the respiration rates. Experiments were performed in a physiological measurement system that allowed simultaneous measures of clearance and respiration rates. During both acclimation and measurements clams were fed with cultured T-iso and temperature was close to seasonal field temperature (10 degrees C....

Respiration of bivalves from three different deep-sea areas: cold seeps, hydrothermal vents and organic carbon-rich sediments
Provedor de dados: 5
Autores: Khripounoff, Alexis; Caprais, Jean-claude; Decker, Carole; Le Bruchec, J.; Noel, Philippe; Husson, Berengere.
We studied bivalves (vesicomyids and mytilids) inhabiting four different areas of high sulfide and methane production: 1) in the Gulf of Guinea, two pockmarks (650 m and 3150 m depth) and one site rich in organic sediments in the deepest zone (4950 m average depth), 2) at the Azores Triple Junction on the Mid-Atlantic Ridge, one hydrothermal site (Lucky Strike vent field, 1700 m depth). Two types of Calmar benthic chambers were deployed, either directly set into the sediment (standard Calmar chamber) or fitted with a tank to isolate organisms from the sediment (modified Calmar chamber), to assess gas and solute exchanges in relation to bivalve bed metabolism. Fluxes of oxygen, total carbon dioxide, ammonium and methane were measured. At the site with...

Resistance of stored-product insects to phosphine
Provedor de dados: 86
Autores: Pimentel,Marco Aurélio Guerra; Faroni,Lêda Rita D'Antonino; Batista,Maurílio Duarte; Silva,Felipe Humberto da.
The objectives of this work were to assess phosphine resistance in insect populations (Tribolium castaneum, Rhyzopertha dominica, Sitophilus zeamais and Oryzaephilus surinamensis) from different regions of Brazil and to verify if the prevailing mechanism of phosphine resistance in these populations involves reduced respiration rates. Sixteen populations of T. castaneum, 15 of R. dominica, 27 of S. zeamais and eight of O. surinamensis were collected from 36 locations over seven Brazilian states. Each population was tested for resistance to phosphine, based on the response of adults to discriminating concentrations, according to FAO standard method. For each insect species, the production of carbon dioxide of the most resistant and of the most susceptible...

Analysis of methodologies for the study of composition and biochemical carbohydrate changes in harvest and postharvest onion bulbs
Provedor de dados: 85
Autores: Abrameto1,MA; Pozzo Ardizzi,CM; Gil,MI; Molina,LM.
Costly investments in storage and transport of onion bulbs makes it increasingly important to identify cultivars with the best chance of long-term storage. This paper discusses our own and other researchers' results and laboratory procedures on onion's pungency, soluble solids, dry matter, respiration rate, carbohydrates and catabolism-related enzymes under different storage conditions. The variability in parameters such as carbohydrate composition, pungency, soluble solids and soluble uronic acid concentration in water is growth dependent, and defines the quality of onion bulbs at harvest time. During storage, these parameters can be modified by environmental conditions, presence of pathogens or termination of dormancy. Under postharvest conditions,...

ABSTRACT  The aim of this work was to evaluate the effect of ethanol and two nitric oxide dose applications on the maintenance of the post-storage quality of ‘Galaxy’ apple during storage under controlled atmosphere (CA). Treatments evaluated were: [1] 1.2 kPa O2 + 2.0 kPa CO2; [2] CA + 20 µL L-1 of nitric oxide, [3] CA + 40 µL L-1 of nitric oxide; [4] CA + 1 ml of ethanol kg-1 fruit. Fruits received treatments before storage and were kept under CA during eight months and seven days of storage at 20 °C. Fruits had been kept on CA for eight months and seven days at 20° C. Fruits treated with ethanol showed higher ethylene production, low flesh firmness, high flesh breakdown, mealiness and acetaldehyde production. Fruits treated with 40 µL L-1 nitric oxide...

‘Desiccation tolerance of Rhamnidium elaeocarpum Reissek (Rhamnaceae) seeds
Provedor de dados: 1
Autores: Silva, Lílian Abadia da; Sales, Juliana de Fátima; Oliveira, João Almir; Pinho, Édila Vilela de Resende Von; Santos, Heloisa Oliveira dos; Soares, Marcos Antônio.
This study aimed to investigate the desiccation tolerance of Rhamnidium elaeocarpum Reissek seeds through physiological and biochemical alterations. Fruit were collected from the municipality of Jaupaci, Goias State, Brazil, when the water content of their seeds had a 37% wet basis (w.b.) and the seeds were subsequently kept in a drying oven with air circulation at a temperature of 35ºC until a water content was reached of 20 to 12% (w.b.). The following parameters were evaluated: germination, germination speed index, emergence, emergence speed index, electrical conductivity and respiration rate. Furthermore, the electrophoretic profile of the isoenzymes: catalase, peroxidase and esterase, the enzymatic activities of endo-β-mannanase and α-amylase and the...

Effect of conductive cooling pads on heat and moisture production  of gilts in hot and thermoneutral environments
Provedor de dados: 111
Autores: Riskowski, Gerald; Shaffer, Christopher S.; Harrison, Paul C.
Swine productivity, reproductivity, and well-being are reduced during periods of high temperature and the most commonly used cooling method, evaporative cooling, is not very effective under high humidity conditions. Conductive cooling pads made from pipes with cool water passing through them have the potential to cool swine under both high temperature and high humidity conditions. A study was conducted to determine some responses of gilts to conductive cooling pads under heat stress conditions. Conductive cooling pads 15 cm wide by 127 cm long were made from 13 mm diameter copper pipe and were fastened to the slatted flooring of a standard sow stall. The size and placement of the pads was such that the gilts could lie on them completely, lie on them...

Metabolic activity of fresh-cut 'Pérola' pineapple as affected by cut shape and temperature
Provedor de dados: 61
Autores: Antoniolli,Lucimara R.; Benedetti,Benedito C.; Sigrist,José M.M.; Souza Filho,Men de Sá M.; Alves,Ricardo E.
The effects of cut shape and temperature on the respiratory activity and ethylene synthesis of fresh-cut 'Pérola' pineapple were investigated. Two experiments were carried out. In the first, slices and chunks were placed in air-tight packages kept at 4 or 10ºC. Gas samples were taken every 2 h during 12 h and analysed by gas chromatography. In the second experiment, peeled fruits, slices and chunks were placed in air-tight glass jars connected to a flowboard installed in a cold room at 5 ± 1ºC. This system provided a continuous flow of humid and cold air during 14 d. Respiration rate was determined every 2 h, during the first 12 h, then daily for 10 d and on days 12 and 14. Ethylene synthesis was not detected during 12 h of evaluation. The lower...

Effect of maleic hydrazide on respiratory parameters of stored onion bulbs (Allium cepa L.)
Provedor de dados: 61
Autores: Benkeblia,Noureddine.
The respiration rate (RR) (CO2 production), activation energy (Ea) and Q10 of maleic hydrazide-treated onion bulbs (Allium cepa, cv. Rouge Amposta) at 20.10-6 mol.L-1 (MH1) and 45.10-6 mol.L-1 (MH2) were measured at 4, 10 and 20ºC. Immediately after treatment, the Q10 of MH-treated and control bulbs were not significantly different. After 8 weeks of storage, Q10 of control and both MH-treated bulbs increased and ranged from 2.34 and 2.89. Respiration rate of onions increased during storage, and after 24 weeks, RR values of control, MH1 and MH2 were 0.43, 0.32 and 0.26 mmol CO2.kg-1.h-1 at 20ºC respectively; and 0.26, 0.20 and 0.17 mmol CO2.kg-1.h-1 at 10ºC respectively. At 4ºC, no significant difference was observed between control and MH-treated bulbs....
