Synergistic application of thermally-pretreated-biocatalyst and dark-fermentative process coupled with bioelectrohydrogenesis promotes biohydrogen production from agricultural straw wastes
Abstract
DF-MEC integrated system enhanced biohydrogen production from wheat straw biomass. Thermally-pretreated activated sludge significantly influenced bioH2 production. The achieved bioH2 yield was 5.416 mmol H2/g-straw with an energy recovery of 94.4 %. DF-MEC promoted further conversion of lignocellulosic fibers and VFAs into bioH2. The maximum COD and NH3-H removal efficiency were 81.32% and 42.25% respectively.
