Chilean crab (Aegla cholchol) as a new source of chitin and chitosan with antifungal properties against Candida spp
Alburquenque, Claudio [Univ Mayor, Fac Med, Grp Microbiol, Chile]; Bernabe, Patricia; Becheran, Liliam; Cabrera-Barjas, Gustavo; Nesic, Aleksandra; Tapia, Cecilia, V.; Taboada, Edelio; Alderete, Joel; De los Ríos, Patricio (Elsevier, 2020)In the present work, the chemical composition of the Chilean freshwater crab Aegla cholchol exoskeleton was studied for the first time. alpha-Chitin was isolated from three main body parts (pincers, legs, carapace), and ... -
Film Dressings Based on Hydrogels: Simultaneous and Sustained-Release of Bioactive Compounds with Wound Healing Properties
Avila-Salas, Fabián [Univ Mayor, Ctr Nanotecnol Aplicada, Fac Ciencias]; Marican, Adolfo; Pinochet, Soledad; Carreno, Gustavo; Valdés, Oscar; Venegas, Bernardo; Donoso, Wendy; Cabrera-Barjas, Gustavo; Vijayakumar, Sekar; Durán-Lara, Esteban F. (MDPI, 2019)This research proposes the rational modeling, synthesis and evaluation of film dressing hydrogels based on polyvinyl alcohol crosslinked with 20 different kinds of dicarboxylic acids. These formulations would allow the ... -
Synthesis and Properties of Poly(imides) and Poly(imides)/Ionic Liquid Composites Bearing a Benzimidazole Moiety
Coll, Deysma [Univ Mayor, Nucleo Quim & Bioquim, Santiago, Chile]; Ortíz, Pablo [Univ Mayor, Nucleo Quim & Bioquim, Santiago, Chile]; Terraza, Claudio A.; Tagle, Luis H.; Pérez, German; Saldias, César; Rodríguez-González, Fidel E.; Cabrera-Barjas, Gustavo; Catalan, Henry; Tundidor-Camba, Alain (MDPI, 2019)Three new aromatic poly(imides) containing benzimidazole units in the backbone were synthesized and characterized by several spectroscopic techniques. Flexible spacer groups were incorporated into the poly(imides) structure ... -
Utilization of industrial by-product fungal biomass from Aspergillus niger and Fusarium culmorum to obtain biosorbents for removal of pesticide and metal ions from aqueous solutions
Cabrera-Barjas, Gustavo; Gallardo, Francisco; Nesic, Aleksandra; Taboada, Edelio; Marican, Adolfo; Mirabal-Gallardo, Yaneris; Delgado, Nacarid; Armas-Ricard, Merly de; Valdés, Oscar; Avila-Salas, Fabián [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile] (Chile. Universidad Mayor, 2020)In this work, Aspergillus niger and Fusarium culmorum cell wall by-products were chosen as microbial sources for chitin and chitosan production. Both polysaccharides were characterized by FTIR and C-13-CPMAS NMR, but GPC ...
