The objective of the present study was to isolate the indigenous iron-oxidizing bacterium and compare its effectiveness in bioleaching of heavy metals from fresh anaerobically digested sludge and aged sludge which had undergone a storage period in a sludge holding tank. An acidophilic iron-oxidizing bacterium Acidithiobacillus ferrooxidans strain ANYL-1 was successfully isolated from the sludge collected from a wastewater treatment plant at Yuen Long district in Hong Kong. It was a Gram… CONTINUE READING
