AB  - The presence of dyes in wastewaters from the textile industry, even in concentrations of less than 1 mg/l, significantlyaffects   the   aesthetic   properties   and   transparence   degree   of   public   effluents,   with   direct   repercussions   on   theenvironment. Cerioporus squamosus White-Rot-Fungi (WRF) strain was used for bio-augmentation of MBBR carriers(consisting of a mix of 88% High Density Polyethylene, 5% talcum and 7% cellulose). Cerioporus squamosus, also oftenencountered as Polyporus squamosus, is a basidiomycete bracket fungus, able to cause “white rot” on decaying wood.The bio-functionalized carriers were used for treatment of a synthetic wastewater sample, of Bemacid ROT (Bezema)azo-dye.   Azoic   dyes   represent   one   of   the   most   important   classes   of   synthetic   dyes   used   in   the   textile   industry,accounting for over 60–70% of the dyes used in this industry. In the case of reactive groups of azo dyes (-N=N-), dueto the low degrees of fixation on the fiber, there are losses of dyes in solution of up to 50%. Infrared spectral (FT-IR)analysis was carried out for determination of functional groups involved in biodegradative processes. Thus, the obtainedIR spectra, different from those of initial Bemacid ROT dye, the disappearance or decrease of the signal specific to azoicbonds from the initial sample, the formation of new functional groups, the disappearance of intermolecular hydrogenbonds simultaneously with increase of transmittance values for amino groups, resulted in highlighting the degradationof Bemacid ROT dye by the bio-augmented HDPE carriers.
