Effect of nitrobenzene on the performance and bacterial community in an expanded granular sludge bed

Jun Li, Wentao Li, Gan Luo, Yan Li, Aimin Li

Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 1, doi: 10.1007/s11783-019-1090-y

Abstract:

Less than 50 mg/L nitrobenzene brought little effect on anaerobic sulfate reduction.

Kinetics of sulfate reduction under different nitrobenzene contents was studied.

Increased nitrobenzene contents greatly changed the bacterial community structure.

Genus Desulfovibrio played the key role in anaerobic sulfate reduction process.
