摘要: Decolourization of anaerobically digested and polyaluminium chloride treated distillery spentwash was studied in a fungal stirred tank aerobic reactor without dilution wastewater. Aspergillus niger isolate IITB-V8 used as the inoculum. The main objectives study were to optimize stirrer speed for achieving maximum decolourization determine kinetic parameters. A mathematical model developed describe batch culture kinetics. Volumetric oxygen transfer coefficient (kLa) obtained using dynamic method. specific growth rate yield fungus determined Logistic equation Luedeking–Piret equation. 150 rpm found be optimum overall 87%. At speed, volumetric 0.4957 min−1 0.224 h−1. values (Yx/s) maintenance (ms) 0.48 g cells (g substrate)−1 0.015 substrate cells)−1
