    Precooked Corn Flour for Venezuelan Arepa Preparation: Characterization of Particle Size Fractions (1985)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 50 (1985), S. 0

    Notes: Commercial precooked corn flour (used for Venezuelan arepa preparation) was sieved into fractions using a Ro-tap shaker. Particles 297 μm thick had the highest consistency. Particles 354 μm thick had the longest stability, their yellow color value (Hunter) was the smallest, and arepas made from them had the highest elasticity. Sedimented volumes were greater for particles 297 μm thick and coarser. Functional properties, evaluated by trained judges, were better for fractions with sizes between 297 and 420 μm. Regression analysis showed that particles between these sizes are the best suited for Venezuelan arepa preparation.

    Description / Table of Contents: Résumé L'ajout d'une étape d'isomérisation à un système couplé pour la production d'éthanol à partir de bagasse de cane à sucre a permis la fermentation éthanolique tant du xylose que du xylulose parSaccharomyces cerevisiae. Le rendement en g d'éthanol par g de bagasse prétraitée a crû selon la méthode de prétraitement: de 0.185 à 0.24 en cas de prétraitement à la soude caustique, de 0.11 à 0.18 dans le cas de Ca(OH)2 et de 0.26 à 0.29 dans le cas de la méthode combinée Ca(OH)2-NaCl.
    Abstract: Resumen Se estudio la inculsión de una etapa de isomerización en el sistema de columnas acopladas, de producción de etanol a partir del bagazo de caña de azúcar, con el fin de permitir asi la fermentación alcohólica de la xilosa. El rendimiento expresado como g etanol/g bagazo pretratado, aumentó dependiendo del tipo de pretratamiento: 0.185 a 0.24 para el pretratamiento con NaOH; 0.11 a 0.18 para el correspondiente a Ca(OH)2 y 0.26 a 0.29 para un tratamiento combinado de Ca(OH)2-NaCl.
    Notes: Summary Ethanol production from sugarcane bagasse holocellulose. Coupled systems for saccharification, xylose isomerization and yeast fermentation. An isomerization step was added to the coupled system for ethanol production from sugar cane bagasse in order to allow the alcoholic fermentation of xylose as xylulose bySaccharomyces cerevisiae. The yield (g ethanol/g pretreated bagasse) was improved according to the method of pretreatment: 0.185 to 0.24 with NaOH pretreatment, 0.11 to 0.18 for Ca(OH)2 and 0.26 to 0.29 for a combined Ca(OH)2/NaCl method.

    Nutrient dynamics within amazonian forest ecosystems (1986)

    Notes: Summary A comparative analysis on the rate of fine litterfall and its associated nutrient fluxes was carried out in a mixed forest on Tierra Firme, a tall Amazon Caatinga and a Bana on podsolized sands near San Carlos de Rio Negro. There was seasonality in leaf fall and total litterfall in mixed forest and tall Amazon Caatinga forest but no definite trend in the Bana. Litterfall curves were significantly correlated among sites indicating common regulating factors in the three forests. Leaf litter from mixed forest on Tierra Firme was richer in N with extremely low Ca and Mg concentrations; tall Amazon Caatinga litter had higher P and Mg concentration, while Bana litter was low in N but K concentration was twice as high as in the other two forests. Annual fine litterfall in Tierra Firme mixed forest was nearly 4 times higher than in Bana, But N flux was 10 times higher, while Ca and Mg fluxes were similar. Tall Amazon Caatinga had Ca and Mg fluxes in litterfall 2–3 times higher than the other two forests. Within-stand efficiency of nitrogen, calcium and magnesium use, as measured by biomass/nutrient ratios, differentiates Tierra Firme from Caatinga and Bana forest: Tierra Firme has the lowest N, but the highest Ca and Mg use efficiencies. Higher P use efficiency was measured in Bana followed by Tierra Firme and Caatinga; while Tierra Firme and Caatinga showed similar higher K use efficiencies than Bana. N/P ratios indicates that Tierra Firme forest is limited by P availability, while low N availability predominates in Caatinga. Bana appears limited by both N and P. These differences probably relate to variations in degree of sclerophylly and leaf duration which determine leaf nutrient concentrations in the ecosystems studied.
