Influence of iron (II) oxide nanoparticle on biohydrogen production in thermophilic mixed fermentation

The effect of initial pH, metal oxide and concentration of nanoparticles (NP) on hydrogen production were investigated in batch assays using glucose-fed anaerobic mixed bacteria in thermophilic condition of 60 �C. Two type of metal oxide nanoparticles, iron (II) oxide and nickel oxide, were teste...
