Abstract

Glycerol is a promising feedstock for microbial cultivation and production of 1, 3 propanediol (1, 3 PDO). Here we report a newly isolated bacterial strain BA11 from soil, capable of fermenting glycerol to 1, 3 PDO, and has been identified to be a strain of Klebsiella pneumoniae. Strain BA11 was fast growing showing peak 1, 3 PDO production in 6 h of cultivation with PRODUCTIVITY of 1.2 g/L-h without the addition of Vitamin B12. Based on the optimum glycerol utilization (75%) and 1, 3 PDO production (8.3 g/L) and yield (0.56 mol/mol glycerol utilized), the most appropriate glycerol concentration for cultivation was 20 g/L. The strain BA11 could tolerate the pH range of 6 to 8.5 as no inhibitory effects were seen on growth as well as 1, 3 PDO production. Strain BA11 was most active and could produce high 1, 3 PDO in the incubation temperature range of 25 to 40°C. The production of 1, 3 PDO was maximum (9.3 g/L) under aerobic condition with 95.8% glycerol utilization. Addition of glucose to the glycerol fermentation led to increased cell mass but no improvement in the 1, 3 PDO production.
