Abstract
The kitchen waste was chosen as a high solid (42 g Lâ1 of volatile suspended solid, VSS) and high organic (107 g Lâ1 of chemical oxygen demand) feedstock for operating a 3-L mesophilic fermentor. The greatest specific hydrogen production rate (rH2) was observed in Stage 3 as 3.4 L-H2 Lâ1 dayâ1 with a volumetric loading rate (VLR) of 100 g-COD Lâ1 dayâ1; the highest hydrogen yield was observed in Stage 2 as 96 mL-H2 gâ1 of influent VSS with a VLR of 46 g-COD Lâ1 dayâ1. In Stages 1 (with a VLR of 27 g-COD Lâ1) and 2, the sum of Butyrivibrio fibrisolvens and Clostridium proteoclasticum is dominant, but in Stage 3, Olsenella genomosp, became dominant and constituted 44% of the entire population. The dependence of VLR and rH2 could be regressed as a linear equation of rH2=(2.83VLR+40.5)Ã10-2.
