Production and Characterization of Biocomposite Films of Bacterial Cellulose from Kombucha and Coated with Chitosan by Márquez Reyes, Julia Mariana, Rodríguez Quiroz, Rubí E., Hernández Rodríguez, Juan Pablo, Rodríguez Romero, Beatriz Adriana, Flores Breceda, Héctor, Nápoles Armenta, Juan, Romero Soto, Itzel C., Galindo Rodríguez, Sergio Arturo, Báez González, Juan G., Treviño Garza, Mayra Zulema

“…The purpose of this research is to produce and characterize bacterial cellulose (BC) filmscoated with chitosan (BC-CH). BC films were produced in a fermentation medium based on Camellia sinensis tea and dextrose (12 days at 25 C) and subsequently treated with coating-forming solutions (CFSs) based on chitosan (BC-CH 0.5%, BC-CH 1.0%, and BC-CH 1.5%). …”

Electrospun Polyvinylpyrrolidone-Gelatin and Cellulose Acetate Bi-Layer Scaffold Loaded with Gentamicin as Possible Wound Dressing by López Calderón, Héctor Daniel, Avilés Arnaut, Hamlet, Galán Wong, Luis Jesús, Almaguer Cantú, Verónica, Laguna Camacho, J. R., Calderón Ramón, C., Escalante Martínez, J. E., Arévalo Niño, Katiushka

“…Through the electrospinning technique, a polymeric scaffold composed of two layers was processed: a gelatin and polyvinylpyrrolidone layer with gentamicin, and a second layer of cellulose acetate. The conditions for the electrospinning process were standardized for voltage parameters, feed flow and the distance from the injector to the collector. …”

Potential of nanocellulose as a dietary fiber isolated from brewer’s spent grain by Morales Juárez, Abraham Azael, Terrazas Armendáriz, Luis Daniel, Alcocer González, Juan Manuel, Chávez Guerrero, Leonardo

“…Such by-products are a source of several components, where cellulose is usually present in high amounts. The aim of this study was to develop a protocol to obtain a mix of cellulose microfibers with an average diameter of 8–12 µm and cellulose nanoplatelets with an average thickness of 100 nm, which has several applications in the food industry. …”
