When only selenate (50 μM) was fed to the UASB reactors (pH 7.3; hydraulic retention time 8 h) with excess electron donor (lactate at 1.38 mM corresponding to an organic loading rate of 0.5 g COD L-1 d-1), the thermophilic UASB reactor achieved a higher total Se removal efficiency (94.4 ± 2.4{\%}) than the mesophilic UASB reactor (82.0 ± 3.8{\%}). When 5000 μM nitrate was further added to the influent, total Se removal was again better under thermophilic (70.1 ± 6.6{\%}) when compared to mesophilic (43.6 ± 8.8{\%}) conditions. The higher total effluent Se concentration in the mesophilic UASB reactor was due to the higher concentrations of biogenic elemental Se nanoparticles (BioSeNPs). The shape of the BioSeNPs observed in both UASB reactors was different: nanospheres and nanorods, respectively, in the mesophilic and thermophilic UASB reactors.
