To produce β-glucosidase by consecutive batch fermentation,a marine Aspergillus nigerwas immobilized on a natural carrier,towel gourd vegetable sponges.The immobilized mycelia were 0.15 g/g carrier with the immobilized biomass percentage of over 95％.The immobilized mycelia possessed the long durability (22.5 days).The maximum production occurred 1.5 day earlier by the immobilized mycelia than by the free mycelia.β-Glucosidase production of five consecutive batches was over 110 U/mL.At high salinity,the activity and stability of β-glucosidase from the marine A.niger increased remarkable.Immobilizing the marine A.niger on the novel natural carrier achieved the efficient production of β-glucosidase.
