Ascorbic acid and calcium uptake in pineapple tissue through different sucrose concentrations of impregnation solution
(Elsevier, 2019-06-19)
Incorporation of ascorbic acid and calcium in pineapple slices through impregnation processes in isotonic (∼14 °Bx) and hypertonic (50 °Bx) aqueous solution of sucrose was studied. Changes in water content, soluble solids, ...
First whole-genome shotgun sequence of a promising cellulase secretor, Trichoderma koningiopsis Strain POS7
(American Society for Microbiology, 2017-09-14)
Trichoderma koningiopsis strain POS7 produces significantly large amounts of cellulase enzymes in solid-state fermentation. The Illumina-based sequence analysis reveals an approximate genome size of 36.6 Mbp, with a G+C ...

Insights into the evolutionary history of an extinct South American freshwater snail based on historical DNA
(Public Library of Science, 2016-12-29)
Highly oxygenated freshwater habitats in the High Paraná River (Argentina–Paraguay) were home to highly endemic snails of the genus Aylacostoma, which face extinction owing to the impoundment of the Yacyretá Reservoir in ...

Chemical composition and biological prospects of essential oils and extracts of aphyllocladus spartioides growing in northwest Argentina
(Wiley, 2017-03-29)
Aphyllocladus spartioides WEDD. is a native and aromatic herb used in traditional medicine, however it is still poorly investigated. In this work, the volatile profile of A. spartioides growing in Hornillos-Northwest ...
Evaluation of the influence of texture and microstructure of titanium substrates on TiO2 anodic coatings at 60 V
(Elsevier, 2017-09-01)
The current paper analyzes the influence of texture and microstructure of Ti substrates on morphology and color of titanium dioxide coatings obtained by anodic oxidation. Substrates of Ti grade 2 and Ti grade 5 with different ...
Influence of the electrolyte concentration on the smooth TiO2 anodic coatings on Ti-6Al-4V
(MDPI, 2017-03-03)
To obtain smooth TiO2 coatings for building a new design of Ti-6Al-4V heart valve, the anodic oxidation technique in pre-spark conditions was evaluated. TiO2 coating is necessary for its recognized biocompatibility and ...
Genetic algorithm applied to parameter estimation of bacterial growth modeling
(Elsevier, 2016-11-14)
Predictive microbiology is nowadays one of the main tools to understand microbial interactions and to assess the quantitative risk in foods. Several models have been developed in order to predict microorganism growth. The ...
Comparison among growth model of interacting microorganism : a lactic acid bacteria and Listeria monocytogenes
(Elsevier, 2017-10-30)
Predictive food microbiology is normally based on mathematical models to predict the growth, inactivation or probability of microorganism growth which can be applied to establish the shelf-life of food. At present the ...
