Outline
A manganese-oxidizing fungal strain designated as ZL8-1 was isolated from the soil in a manganese mining area and identified as Aspergillus flavipes based on morphological characteristics and molecular phylogenetic method. The strain exhibited rapid growth, reaching colony diameter of 5.44 cm on AY medium in 7 days of incubation. A. flavipes ZL8-1 demonstrated strong manganese tolerance, withstanding concentrations up to 8 mmol/L, and showed minimal growth inhibition at 1-4 mmol/L Mn2+. The highest manganese removal efficiency of 77.50% was achieved at concentration of 1 mmol/L over 22-day period. A. flavipes ZL8-1 could be regarded as a promising microbial resource for manganese bioremediation.
