Cellulose, the most abundant polysaccharide on Earth, is synthesised not only by plants but also by bacteria. The symbiotic group of microorganisms found in kombucha is best known for its probiotic properties. In addition, it produces one of the purest forms of cellulose found in nature, in the form of a hydrogel structure called SCOBY (Symbiotic Consortium of Bacteria and Yeast). Bacterial cellulose has the capacity to process organic waste and replace plastic products in everyday life. The cultivation process is simple, does not require laboratory conditions and can utilise bio-waste by converting carbon into polysaccharides. Kombucha is one of the most prominent candidates for future use in isolated extreme environments in life support systems. This article characterises kombucha-derived biomaterials and provides simplified methods for their production in the resource-limited environments.
