Abstract

A moderately thermophilic iron-oxidizing bacterium strain TI-1 has been shown to have a unique enzyme system that produces hydrogen sulfide (H₂S) extracellularly under acidic conditions. The optimal culture conditions for H₂S production were determined to apply the bacterium to the treatment of acidic wastewater containing heavy metals. The production of H₂S by the cells was dependent on L-glutamic acid, ferrous sulfate and elemental sulfur in the medium. The optimal culture medium for H₂S production contained 0.3% L-glutamic acid, 1.7% ferrous sulfate, and 1.0% elemental sulfur and the optimal pH and temperature were 4.0 and 55 °C, respectively. Under the optimal culture conditions, strain TI-1 produced H₂S continuously at a rate of 0.26 μmol/ml/d for 14 d.
