Nanocomposite material based on bacterial cellulose and hydroxyapatite was obtained using the biomimetic mineralization method (imitation of the formation of the mineral component in natural bone tissue) and the synthesis of hydroxyapatite nanoparticles in the presence of fibrillar fragments of BC. The biocomposite BC/HA-1 obtained by biomineralization showed high physicochemical parameters compared with the composite obtained by synthesis of hydroxyapatite nanoparticles in the presence of fibrillar fragments of BC (BC/HA-2). The ultimate tensile strength of the composite BC/HA-1 was 92.07+1.4 MPa, the composite BC/HA-2 was 76.09+1.1 MPa. Young's modulus (the coefficient of proportionality between stress and strain) of the BC/HAP-1 composite was 59.04+0.6 MPa (BC/HA-1), which is 18.6% higher than that of the BC/HA-2 composite (48.03+0.8 MPa).
