<P><B>Abstract</B></P> <P>This study presents the effects of nanoscale zero valent iron (nZVI) concentration on the biomethanation of gaseous CO<SUB>2</SUB>. During anaerobic batch experiment with 9 times injection of CO<SUB>2</SUB>, the CO<SUB>2</SUB> concentration in the headspace rapidly decreased by dissolution. Then, when nZVI was added at 6.25 and 12.5 g/L, the dissolved CO<SUB>2</SUB> was biochemically transformed into CH<SUB>4</SUB> at a maximum production rate of 2.38 and 3.93 μmol/hr, respectively. Biomethanation at these two nZVI concentrations continued until the end of experiment. In spite of more H<SUB>2</SUB> evolution by nZVI at 25 g/L, biomethanation did not occur, due to the significant inhibition of methanogenesis by nZVI. As the nZVI concentration increased, relative abundance of the hydrogenotrophic methanogens, especially <I>Methanobacteriales</I>, increased. However, at 25 g/L of nZVI concentration, acetic acid was accumulated and the relative abundance of <I>Clostridium</I> became predominant, indicating that homoacetogenesis was superior over methanogenesis.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Biomethanation of CO<SUB>2</SUB> coupling with nZVI corrosion was suggested. </LI> <LI> Biomethanation rate was highly affected by the nZVI concentration. </LI> <LI> Excessive nZVI addition promoted homoacetogenesis rather than methanogenesis. </LI> <LI> qPCR supported the biomethanation depending nZVI concentration. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
