摘要: Aim of this study was to evaluate the suitability ensiled giant reed, maize, olive pomace, wheat bran for combined systems (CS: dark fermentation+anaerobic digestion (AD)) producing hydrogen-rich biogas (biohythane), tested in batch under basic operational conditions (mesophilic temperatures, no pH control). Substrates were also analyzed a single stage AD test, order investigate effects DF on estimated energy recovery (ER) systems. In CS, maize and exhibited highest hydrogen potential (13.8 18.9NLkgVS(-1)) methane (243.5NLkgVS(-1)). one-stage AD, showed production (239.5, 267.3 260.0NLkgVS(-1)). Butyrate/acetate ratio properly described fermentation, correlating with (r=0.92). Wheat proved be promising residue CS terms hydrogen/methane ER.
