Abstract

This work investigated the effects of eight metal ions on Rhodopseudomonas palustris growth and 5-Aminolevulinic acid (ALA) yield in wastewater treatment. Results show that metal ions (Mg²⁺ of 15 mmol/L, Fe²⁺ of 400 μmol/L, Co²⁺ of 4 μmol/L, Ni²⁺ of 8 μmol/L and Zn²⁺ of 4 μmol/L) could effectively improve the chemical oxygen demand (COD) removal, Rp. palustris biomass and ALA yield. The highest ALA yield of 13.1 mg/g-biomass was achieved with Fe²⁺ of 400 μmol/L. ALA yields were differentially increased under different metal ions in the following order: Fe2t group Mg2t group Co²⁺ group. Ni²⁺ group>Zn²⁺ group. Mo²⁺ group control. Cu²⁺ and Mn²⁺ inhibited Rp. palustris growth and ALA production. Mechanism analysis revealed that metal ions changed ALA yields by influencing the activities of ALA synthetase and ALA dehydratase.
