The use of the fungus Dichomitus squalens for degradation in rotating biological contactor conditions

► Selection of a fungus for use in rotating biological contactor (RBC) for remediation. ► Biochemical and degradation properties of biofilms of selected Dichomitus squalens determined. ► The role of MnP and laccase in degradation of anthraquinone dye proven. ► The fungus degraded anthraquinone and phenothiazine dyes in RBC with >90% efficiency. ► The fungus tolerant to bacterial stress by coliform and non-coliform bacteria.
