Cover Story: The biodiesel industry generates 5.5 billion liters of glycerol-rich residue annually. Certain Clostridium species can convert glycerol into 1,3-propanediol (1,3-PDO), a product in high demand within the polymer industry. This study optimized glycerol and ammonium sulfate concentrations to enhance 1,3-PDO production by Clostridium beijerinckii Br21. The optimized concentrations resulted in a 112% increase in 1,3-PDO concentration. Gene expression analysis revealed the significant upregulation of genes related to the oxidative and reductive pathways of 1,3-PDO biosynthesis. The results support glycerol and ammonium sulfate optimization as an effective strategy for improving 1,3-PDO production, demonstrating the potential of the bioconversion of glycerol-rich residues into value-added products.
