title: Acrylic acid removal from synthetic wastewater and industrial wastewater using Ralstonia solanacearum and Acidovorax avenae isolated from a wastewater treatment system manufactured with polyacrylonitrile fiber.
abstract: Ralstonia solanacearum and Acidovorax avenae were isolated from a wastewater treatment system manufactured with polyacrylonitrile fiber. The investigation goal is to elucidate the effectiveness of Ralstonia solanacearum and Acidovorax avenae in treating acrylic acid from synthetic wastewater and industrial wastewater. The results reveal that Ralstonia solanacearum and Acidovorax avenae could utilize acrylic acid from synthetic wastewater for growth, when the initial acrylic acid concentration was below 1,009.1 mg/l and 1,383.4 mg/l, respectively. When the acrylic acid concentration was below 606.8 mg/l, the acrylic acid removal ability reached 96.7% and 100%, respectively. Both strains could tolerate acrylamide toxicity, but only Ralstonia solanacearum could tolerate acrylonitrile toxicity. Ralstonia solanacearum and Acidovorax avenae could utilize acrylic acid from industrial wastewater for growth, when the initial acrylic acid concentration was below 1,741.1 mg/l and 1,431.2 mg/l, respectively. When the acrylic acid concentration was below 690.8 mg/l, the acrylic acid removal efficiency reached 83.5% and 62.2%, respectively. Whether the acrylic acid existed in synthetic wastewater or in industrial wastewater, the removal efficiency of acrylic acid by Ralstonia solanacearum exceeded that by Acidovorax avena.
