ABSTRACT
Kinetic parameters for mesophilic anaerobic digestion of poultry droppings were determined experimentally in a batch reactor using mixed culture of indigeneous microorganisms isolated from the waste. The maximum rate of substrate utilization (K), yield coefficient ( ), saturation constant (Ks), endogeneous decay coefficient (Kd) ,COD removal efficiency(CODreff) and maximum specific growth rate ( ) were found to be 1.09 day-1, 0.09 , 73.015 mg/L , 0.065day-1 ,0.71 and 0.139 day-1 respectively. These biokinetics parameters if well annexed could prove invaluable in the efficient operation, design and control of bioreactors for mesophilic anaerobic digestion of poultry droppings for pollution control, energy and fertilizers for soil conditioning.
