摘要

In this research the production of hydrogen by Klebsiella pneumoniae BLbOl using residual glycerol discharged from a biodiesel fuel production plant was investigated. Klebsiella pneumoniae BLbOl was isolated from a bacteria-rich sludge of an upflow anaerobic sludge blanket reactor (UASB) of a soybean processing plant. A Plackett-Burman design (P-B) and Response Surface Methodology (RSM) were employed to determine the optimal condition for enhanced hydrogen production. The maximal hydrogen production, which was 45.0 mol % and with 98% of glycerol degradation, was achieved with the optimized medium with the following composition: 30 g L~(-1) glycerol; 3 g L~(-1) yeast ex tract 3 g L~(-1) K_2HPO_4; 1 g L~(-1) KH_2PO_4; temperature 39℃ and pH 9.0. These results show the ability of this new strain of effectively converting residual glycerol into value-added energy products.
