초록

1.3-Propanediol as a bifunctional organic compound could potentially be used for many synthesis reactions, in particular as a monomer for polycondensations to produce polyesters, polyethers and polyurethanes. Wastewater containing high concentration of glycerol was used to produce 1,3-propanediol in lower production cost which inturn the quantity of wastewater to be treated. In this study, various attempts were made to increase 1,3-propanediol production under different conditions by Klebsiella pneumoniae ATCC 15380. 1,3-Propanedio conversion yield and by-product formation were influenced significantly by pH and temperature. The Optimal glycerol and nitrogen concentration for 1,3-propanediol production were found to be 25g/L and 1%(w/v), respectively. The production formation of 1,3-propanediol was optimal at pH 6.0 and temperature $35^{\circ}C$.
