Xylem anatomical traits can provide insights regarding the mechanisms affecting the distribution of vascular plants across environmental gradients. In this study, we aimed to investigate the hypothesis that lianas occurring in semiarid environments have characteristics that maximize the xylem resistance to tension-induced cavitation along the root-stem-branch continuum. To gather information regarding the hydraulic architecture of the lianas, we analyzed several anatomical traits of wood: cross-sectional area occupied by the parenchyma (AP), fibers (AF), and vessels (AV); average vessel diameter (d); wood density (WD); pit diameter in the vessel wall (dpit); pit density (Npit), and potential hydraulic conductivity (Kp) in branches, stems, and roots of... |

O objetivo do trabalho foi verificar a qualidade higiênico-sanitária de amostras de queijo de coalho (11 amostras) e de queijo de manteiga (13 amostras) produzidas no Estado do Rio Grande do Norte. Todas as amostras de queijo de coalho apresentaram coliformes totais, das quais 36,4% continham coliformes fecais, entre 3 a 7NMP/g , com confirmação de Escherichia coli. Em relação ao queijo de manteiga, 84,6% das amostras também apresentaram coliformes totais, 15,4%, coliformes fecais, com confirmação de E. coli em 7,7%. A contagem de bolores e leveduras variou de 1,9 x 10(4) a 4,8 x 10(8) UFC/g nas amostras queijo de coalho e de 1,5 x 10(4) a 2,8 x 10(8) UFC/g nas amostras de queijo de manteiga. Estafilococos coagulase positiva foi observado em 72,7% das... |

Abstract: The objective of this work was to determine a suitable combination of the polysaccharide mesquite seed gum (MSG) and the protein Nile tilapia fish gelatin in the composite MSG/gelatin film for food packaging applications, and to evaluate the effect of cellulose nanocrystals (CNCs) on the film. MSG and gelatin were extracted from mesquite seeds and Nile tilapia residues, respectively, and the CNCs from mesquite pods by acid hydrolysis. The MSG:gelatin ratio with the best combination of tensile and barrier properties was used to produce the bionanocomposite films, by adding different CNC contents to the MSG/gelatin dispersion. The MSG:gelatin ratio of 1:1 had a good combination of water vapor permeability (WVP) and tensile strength. The properties... |
