| Abstract Scope |
Cellulose is a natural polymer considered the most abundant on Earth, being synthesized by all classes of plants, bacteria, fungi, and algae; it is a sustainable material due to its abundance, renewability, and degradability.
Bacterial cellulose (BC) is a polysaccharide widely studied due to its excellent biological and physicochemical properties such as biocompatibility, biodegradability, nontoxicity, flexibility, and chemical stability. It has higher crystallinity, purity, tensile strength, and Young´s modulus than cellulose produced by plants. For that, Kombucha is a sweetened beverage produced by fermentation of black or green tea and SCOBY (Symbiotic Culture of Bacteria and Yeast) for a 7-14 days period, resulting in a floating cellulose layer on the liquid-air interface which protects the medium from UV radiation and microorganisms.
For the above, in this work, Kombucha BC was obtained and characterized by SEM, TGA, and FT-IR, for using in biodegradable films. |
