The immobilization of microbial cells on eco-friendly supports is a promising technique to obtain effectively immobilized biomaterials for the biotreatment of aquatic pollution. For the biosorption of reactive dyecontaminated water, a new immobilized biosorbent, rose waste/Mucor plumbeus cells (RWMPC) composite was designed by immobilizing the fungal cells on a process waste of the rose oil industry. Batch and continuous mode biosorption features of RWMPC under different pH, initial dye concentration, contact time, biomaterial dose, and effluent flow rate conditions were examined. Zeta potential measurements, FT-IR, and SEM analysis were used to determine the morphological features of the biomaterial and possible Reactive Blue 49 (RB49)biomaterial interactions. Kinetic investigations revealed that Ho's pseudo-second-order kinetic model could offer the best data fitting for biosorption, while the Freudlich model best matched the equilibrium data. Immobilized biomaterial displayed a high biosorption capacity of 120.88 mg g(-1). With an appropriate flow rate and amount of RWMPC packed into the column, dynamic treatment tests demonstrated >90% biosorption efficiency. The breakthrough curve of the RWMPC column adequately fits Chu's simplistic model. Regeneration tests revealed that after ten consecutive cycles, the biosorption yield and recovery efficacy of RWMPC were >65 and 85%, respectively. Zeta potential tests, SEM micrographs, and FT-IR studies also verified the dye uptake. Using synthetic wastewater in a continuous system, RWMPC could remove >90% of RB49. Breakthrough and exhaustion points were identified, and the maximum exhaustion capacity value was computed as 127.6 mg g(-1). The results might inspire a fresh approach to the problem of reactive dye contamination in waters.
