  • Cell encapsulation using chitosan: chemical aspects and applications

    • Authors: Maura Rojas Pirela; Verónica Rojas, Elizabeth Pérez Pérez, Cristóbal Lárez Velásquez
      Abstract: In this work, the main approaches for the preparation of encapsulating matrices using chitosan-containing formulations have been reviewed. Various methodologies have been considered, such as physical intermolecular bonds and chemical cross-linking reactions, including the click reactions which have become novel in the cross-linking of systems containing this biopo-lymer. Likewise, the formation of different macroscopic assemblies such as spheroids, vesicles, layer by layer polycomplexes, etc., has been addressed. In the final part of the work, the main achievements reported with these matrices in the encapsulation of cells, both eukaryotic and prokaryotic, are discussed, emphasizing their potential applications and perspectives in different fields as medicine (treatment of traumatic diseases, diabetes, venous diseases, tissue regeneration, transplantation and toler-ance); food (administration of probiotics); industrial applications (bioethanol production); etc.Recibido: 07/10/2021

      Abstract: Estudo fitoquímico e atividades biológicas in vitro dos extratos de Chlorella vulgaris, Chlorella pyrenoidosa e Chlorella minutíssima. O estudo teve como objetivo a triagem de compostos fitoquímicos e avaliação das atividades biológicas dos ex-tratos de Chlorella vulgaris, Chlorella pyrenoidosa e Chlorella minutissima (aquoso e hidroetanólico). Foi realizado fitoquími-ca, varredura em espectrofotometria, fenólicos e flavonoides totais, eliminação do radical DPPH e a atividade antioxidante to-tal, atividade antibacteriana foi realizada sobre Staphylococcus aureus, Escherichia coli, Salmonella sorovar Enteritidis e Thyphymurium e citotóxica sobre Artemia salina. Os extratos exibiram a presença de diversos grupos fitoquímicos, alto con-teúdo de flavonoides e fenólicos totais, expressivas atividades redutoras para DPPH e %AA. A inibição foi positiva para cepas bacterianas e baixa atividade citotóxica.Recibido: 30/11/2021

  • Residuos lignocelulósicos como materia prima de segunda generación en
           procesos de biorrefinación

    • Authors: Andrea Briones Muñoz; María Antonieta Riera
      Abstract: Existe interés mundial en reemplazar los combustibles fósiles por fuentes renovables. La primera generación de biorrefinerías se basó en la utilización de cultivos alimentarios, lo que generó un debate sobre alimentos contra combustible y una sostenibilidad cuestionable. Para superar esto, se propuso el uso de materias primas lignocelulósicas incluyendo desde cultivos no alimentarios hasta residuos y desechos agroforestales. Atendiendo a esta premisa, se realizó una revisión bibliográfica sobre el uso de residuos lignocelulósicos de segunda generación para la producción de bioproductos. Se investigó acerca de los procesos de transformación empleados, los bioproductos obtenidos y la cantidad de residuos de este tipo que están disponibles en Latinoamérica para su uso. El aprovechamiento de este tipo de residuos brinda una oportu-nidad para el desarrollo de la región al utilizar materia prima de bajo costo para la obtención de productos con valor agregado.Recibido: 17/10/2021

  • Síntesis y caracterización estructural del compuesto
           hidantoína de D,L-valina

    • Authors: Ronald Márquez; Lusbely M. Belandria, Marilia Guillén, Teresa González, Asiloé J. Mora, Gerzon Delgado
      Abstract: La hidantoína de D,L-vailna, un nuevo derivado hidantóico de '-aminoácido, con fórmula C6H10N2O2, ha sido sintetizado y caracterizado estructuralmente mediante las técnicas IR, RMN, y difracción de rayos-X. Los resultados espectroscópicos son consistentes con el esqueleto molecular. El patrón de difracción de rayos-X en polvo confirma la pureza de la muestra cristalina. El análisis por difractometría de cristal único indica que el compuesto cristaliza en el sistema monoclínico, grupo espacial P21/c (Nº14), con parámetros de celda unidad: a= 5,493(3) Å, b= 23,53(2) Å, c= 6,254(3) Å y ß= 115,09(4)º, V= 732,1(9) Å3, Z= 4. El empaquetamiento cristalino está estabilizado por enlaces de hidrógeno fuertes del tipo N--H···O entre los anillos hidantoinicos vecinos; formando los grafos: C(5), R22(8) y R44(16). Además, la estructura cristalina presenta en-laces de hidrógeno no convencionales del tipo C5--H5···O2 e interacciones '···' entre los bordes del anillo hidantoína. La interacción de todos estos tipos de enlaces de hidrógeno, junto a fuerzas dispersivas presentes en las regiones donde se en-cuentran los grupos isopropilos, estabilizan el eficiente empaquetamiento de la estructura con un índice de espacio ocupado de 66,3%.Recibido: 30/11/2021

    • Authors: Ileana C. Ciapparelli; Alicia Rosa Fabrizio de Iorio, Ana Rosa García
      Abstract: Con el propósito de determinar la capacidad base o inicial de retención de fósforo en un suelo Argialbol, soporte de un establecimiento de engorde intensivo de Argentina, se tomaron muestras del mismo en profundidad y se analizaron sus características. Se realizaron ensayos de isotermas de adsorción de fósforo y los modelos de Langmuir, Freundlich, Temkin y Dubinin-Radushkevich fueron ajustados a los datos experimentales. Los tres horizontes superiores presentaron partículas con sitios de mayor afinidad y energía de enlace que las de los horizontes profundos. Se demostró una adsor-ción favorable en todo el perfil, influenciada principalmente por variables como materia orgánica, arcilla y potasio.Recibido: 03/11/2021
