Integrated process for protein, pigments, and biogas production from baker's yeast wastewater using filamentous fungi

• -Baker's yeast wastewater is among the severe environmental threat with 29000 mg/L COD. - M. indicus , hiemalis N. intermedia and A. oryzae were grown on wastewater. Fungi reduced total COD of by 36.3%. Fungal biomass has valuable amino acids minerals for aquaculture feed. The effluent remained was anaerobically digested to biogas further remove Baker's production industry generates large quantities high chemical oxygen demand (COD) integration baker's (BYW) an innovative two-step waste biorefinery process producing protein-rich fungal along nutrients removal main object present research. In first step, from BYW investigated using four species filamentous fungi. maximum yield 5.13 g/L containing 43.8% mycoprotein 36.3% achieved . second produce organic matter, fermentation subjected anaerobic digestion between 22.4 44.2% obtained. Overall, 1 m 3 yielded kg 1.42 methane. Additionally, pigment investigated, 1.54 mg carotenoids/g produced.
