Bacterial cellulose (BC) is a fascinating polysaccharide produced by bacteria in the form of a swollen gel‐like membrane with the function of a protective structure. The isolation of the cellulose‐producing strains begins with the search for a microorganism source. The growth of the microorganism and cellulose production depends on the optimal combination of nutrient sources, including carbon, nitrogen, and mineral salts, for each specific strain. Purification of the cellulose fibers with microorganisms is based on killing the microorganisms and removal of cell wastes and residues of the liquid culture media from the cellulose matrix. The most important properties of BC are their mechanical strength, water content, high degree of crystallinity, and high purity. Properties of BC such as biocompatibility make possible its application in biological and biomedical fields, where it can be used as single material or as a component of biocomposites.
