Aspergillus carbonarius NRC 401121 adsorbs some copper and chromium from their solutions. The amount of the adsorbed metal per unit of biomass increased with a decrease in the biomass concentration. The increases in the initial concentrations of metals and pH of the solutions resulted in an increase in copper and chromium uptake. The optimum temperature for copper uptake was 25 degrees C. Heating of the biomass prior to utilizing it in the adsorption tests decreased its metal adsorption capacity. Preincubation of the biomass with glucose enhanced the metal adsorption. The optimum glucose concentration in this process was 0.1%.
黑曲霉NRC 401121能从其溶液中吸附一些铜和铬。每单位生物量吸附的金属量随生物量浓度的降低而增加。金属初始浓度和溶液pH值的增加导致铜和铬的吸收量增加。铜吸收的最适温度为25℃。在吸附试验中使用前对生物量进行加热会降低其金属吸附能力。生物量与葡萄糖预孵育可增强金属吸附。此过程中的最佳葡萄糖浓度为0.1%。
