Bacterial cellulose is a natural polymer produced by certain bacteria, primarily Acetobacter species. It forms a gel-like substance that is highly pure and has a unique nanostructure, making it different from plant cellulose. This material is known for its high tensile strength, water retention capacity, and biocompatibility, which makes it useful in various applications. Due to its properties, bacterial cellulose is used in fields such as food, medicine, and cosmetics. It can serve as a thickening agent in food products, a scaffold for tissue engineering in medical applications, and a moisturizing agent in skincare products.
