Conidia formation of Aspergillus oryzae in wheat bran powder medium.

A. oryzae was grown in wheat bran powder media at K2HPO4 concentrations of 0.02% (left) and 0.05% (right). As shown in these micrographs, an increase in the amount of phosphate resulted in more conidia. This increase is likely to be associated with the increased production of dye-decolorizing peroxidase, which can be applied to treat colored wastewater.
