SCOBY cellulose (CS) is a biopolymer with exceptional physical properties, serving as a source of fiber, water retention capacity, crystallinity, and purity. Its potential as a byproduct of kombucha production and a source of bacterial cellulose (BC) has been a subject of exploration. This study aims to gather information from experimental studies in the scientific literature on various methods of CS extraction, processing, and purification, and their impact on microscopic, macroscopic structure, and functional characteristics. The purification treatments for CS, as described in the literature, include immersion in deionized, distilled, or sterile water, sodium hydroxide, hydrogen peroxide, and sodium hypochlorite under agitation or static mode at different temperatures (23ºC, 30ºC, 50ºC, 80ºC, 90ºC, 110ºC) and under variable contact times with the substance chosen for treatment (1, 2, 20, 24 hours to 3 days). Alkaline treatments on SCOBY cellulose enhance extensibility, viscoelasticity, absorptivity, tensile strength, heat stability, and remove microorganisms, sugars, and other components of the culture medium adhered to the cellulose. With CS being obtained at a low cost and low complexity in the fermentation process, and the potential for less polluting treatments, it presents a sustainable process and source of CB that can be applied in a variety of industries, particularly in the exciting field of food.
