The commercial utilization of cassava leaves, as a source of protein and raw material for biofuels involves establishing conditioning and storage schemes to enable processing throughout the year, despite the seasonal nature of the harvest. Drying serves as the primary separation process for conditioning prior to storage of this type of material, an...
Considering that global awareness for sustainable development has risen to face environmental damages, different building materials have been considered from a mechanical perspective. In this sense, considering the richness of South America regarding its woods, the Guayacan and the Ecuadorian oak timbers have not been previously characterized. The...
The aim of this study was to evaluate biomass generation and determine the total lipid content of a microalgae isolated from a lagoon of the Ecuadorian Amazon. The morphological identification of the isolated microalgae was done through bibliographic comparisons and molecular identification by PCR followed by DNA sequencing and phylogenetic analysi...
Microalgae are photosynthetic microorganisms with high lipid content, capable of degrading nutrients from wastewater. In this research, two strains of microalgae, Scenedesmus sp. and Chlorella vulgaris were cultivated in sterilized pig slaughterhouse wastewater using outdoor flat photobioreactors. Cell growth, total lipids, free fatty acids (FFA),...
Diversas investigaciones respaldan el uso de microalgas como fuente de productos de interés biotecnológico, pero aún existen limitaciones para su implementación; como el uso de aguas residuales como medio de cultivo y la generación de biomasa en presencia de otros microorganismos que compiten por los nutrientes. En este estudio se compararon 3 méto...
Combustion gases generated by fossil fuels, are the principal source of environmental problems now a days; transport sector is worldwide, one of the main cause of environmental damage, primarily in populated cities. Biofuels are an alternative that has awake the attention of governments and institutions due to the significant decrease of harmful em...
El objetivo de este estudio fue el de generar bases de diseño para secadores agroindustriales a escala industrial para bagazo de caña tratado (BCT) y no tratado (BNT) con presurización y despresurización amoniacal (PDA) en biorefinerías de producción de etanol de segunda generación, a través de la medición de la cinética de secado a 55, 65 y 75 ºC....
El contenido y calidad de las proteínas presentes en las hojas de yuca les dan la potencialidad de ser un sustituto parcial de la harina de soja en las formulaciones para cerdos y aves, siendo uno de los residuos del campo de mayor producción en algunas regiones de América Latina. Su secado post-cosecha disminuiría los costos de transporte y almace...
Las conchas de cangrejo azul (Callinectes sapidus) y camarón marino (Litopenaeus schmitti), son los residuos pesqueros de mayor producción en la cuenca del Lago de Maracaibo en Venezuela y representan un grave problema ambiental. Su uso como materia prima de biorefinerías para producción de quitosano y otros subproductos como proteínas, minerales y...
