Resumo(s): | Proof of principle of biohythane and potential energy production from garden waste (GW) is demonstrated in this study in a two-step process coupling dark fermentation and anaerobic digestion. The synergistic effect of using co-cultures of extreme thermophiles to intensify biohydrogen dark fermentation is demonstrated using xylose, cellobiose and GW. Co-culture of Caldicellulosiruptor saccharolyticus and Thermotoga maritima showed higher hydrogen production yields from xylose (2.7±0.1 mol mol -1 total sugar) and cellobiose (4.8±0.3 mol mol-1 total sugar) compared to individual cultures. Co-culture of extreme thermophiles C. saccharolyticus and Caldicellulosiruptor bescii increased synergistically the hydrogen production yield from GW (98.3±6.9 L kg-1 (VS)) compared to individual cultures and co-culture of T. maritima and C. saccharolyitcus. The biochemical methane potential of the fermentation end-products was 322±10 L kg-1 (CODt). Biohythane, a biogas enriched with 15% hydrogen could be obtained from GW, yielding a potential energy generation of 22.2 MJ kg-1 (VS). |
