In this work, chitosan cross-linked cellulose fibers were prepared using non-toxic and eco-friendly procedures in order to confer antimicrobial properties to cellulose fibers. Initially, commercial chitosans and chitooligosaccharides were physico-chemically characterized and the latter were tested by assays in vitro. Chitosan was selected based on molecular weight and acetylation degree....
Chitin is a biodegradable biopolymer that can be obtained from shrimp wastes employing thermochemical and biological methods. The latter are emerging as a green, cleaner, eco- friendly, and economical process. In this regard, lactic acid fermentations (LAF) of shrimp wastes (Litopeneus vannamei) were carried out with starters of lactic acid...
La quitina y el quitosano (obtenido por la desacetilación de la quitina), son biopolímero s extraídos de desperdicios de crustáceos que cuentan con distintas aplicaciones, como médicas y farmacéuticas, entre otras. La quitina se extrae comúnmente mediante el uso de químicos para eliminar los minerales y proteínas que se encuentran...
