Microbial community dynamics at high organic loading rates revealed by pyrosequencing during sugar refinery wastewater treatment in a UASB reactor

Liguo Zhang, Qiaoying Ban, Jianzheng Li

Frontiers of Environmental Science & Engineering 2018, Volume 12, Issue 4, doi: 10.1007/s11783-018-1045-8

Abstract:

High strength sugar refinery wastewater was treated in a mesophilic UASB.

Pyrosequencing reveals microbial community succession with OLR increase.

Diversity of microbial communities in OLR12 is much higher than those in OLR36 and OLR54.0 kgCOD/(kg VSS·d).

Fermentative bacteria could deal with increasing OLR through the increase of microbial diversity and quantity.

Hydrogen-producing acotogens and methanogens mainly coped with high OLR shocks by increasing the quantity of community
