摘要: Abstract Properties of bacterial nanocellulose (BNC) produced by four different strains were studied and compared for laccase immobilization. Scanning electron microscope inspection indicated the types BNC had obvious differences in fiber density, diameter distribution. hydrogel demonstrated highest fracture stress 2.44 Mpa Young's modulus 12.76 Mpa. Brunauer-Emmett-Teller analysis suggested significant difference specific surface area, total pore volume average size. Laccase was immobilized on carriers via adsorption. Kinetic studies showed that BNC-immobilized affinity with substrate, all high operational stability after ten consecutive biocatalytic cycles reaction. The results suggest structure diversity from various may directly result efficiency immobilization, a looser network larger porosity is helpful enzyme
