A method for producing bacterial cellulose, said method comprising culturing a biologically pure culture of a cellulose-producing Proteus strain in a liquid medium suitable for culturing facultatively anaerobic microorganisms, separating bacterial cellulose produced in said liquid medium from said liquid medium, washing said separated bacterial cellulose and drying said bacterial cellulose. The cellulose-producing Proteus strain is preferably a Proteus myxofaciens strain, preferably strain IDAC 071005-01 or strain ATCC 19692. The liquid medium is provided with a carbohydrate substrate containing at least one sugar selected from the group consisting of glucose, sucrose, fructose, lactose, xylose, and rhamnose. A bacterial cellulose product produced by culturing a biologically pure culture of a cellulose-producing Proteus strain in a liquid medium suitable for culturing facultatively anaerobic microorganisms.
