Batch fermentation for H2 production with a new bacterium Enterobacter asburiae SNU-1 isolated from domestic landfill |
| 초록 |
Recently, there has been growing interest in biological hydrogen production which is found to be environmental. Bio-hydrogen is produced by photosynthetic or fermentative bacteria. In this study, the fermentative hydrogen producing bacterium was isolated from several domestic landfill areas and identified as Enterobacter asburiae SNU-1. This microorganism is a new species that has not been studied for hydrogen production. The strain, Enterobacter asburiae SNU-1, produced hydrogen during the dark fermentation. Important factors were investigated including pH, the concentration of initial glucose, the concentration of initial yeast extract, the concentration of initial bacto peptone, and different carbon sources. The hydrogen production started when cell growth entered early exponential phase and reached maximum production rate at the stationary phase. The hydrogen production continued for a long time even after the stationary phase. This microorganism produced more hydrogen at stationary phase than at exponential phase. The maximum volumetric hydrogen production rate was estimated to be 417.2 ml H2/l/hr on concentrations of 15 g glucose/l. |
