We found that neither the meso- nor thermophilic methanogenic
communities were influenced significantly by OLRs in concentrations
of 1e10 kg VS m3 d1. A recent study treating
pharmaceutical wastewater (Chelliapan et al., 2011) concluded that
Methanosaeta generally dominated at low OLRs of 0.86e
1.86 kg COD m3 d1
