摘要:
Aspergillus oryzae was isolated from radionuclides’ contaminated soils, and dielectric barrier discharge plasma was used to mutate A. oryzae to improve bioremediation capability of U(VI) pollution. The maximum accumulation capacities of U(VI) on mutated A. oryzae was 627.4 mg/g at T = 298 K and pH = 5.5, which was approximately twice than that of raw A. oryzae. XPS analysis indicated that U(VI) accumulation on mutated A. oryzae was largely attributable to nitrogen- and oxygen-containing functional groups on fungal mycelia. The mutated A. o...
