Microbial fermented cellulose gel, citrus gel(CG), was successfully fabricated to porousfoam by radiation treatment and freeze drying. The chemically induced radiation was used to createhighly porous foam and further freeze drying of the CG produced tough foams with interconnectedopen pores for use in tissue engineering. The microstructure of the CG foam was controlled byvarying the irradiation dose and quenching temperature with pore size ranging from several micronsto a few hundred microns. Tensile strength and Gurley value of the CG foam were influenced byirradiation dose. These radiation induced CG foams are promising scaffolds for tissue engineering.
