Two stage mesophilic acidogenicethermophilic methanogenic
anaerobic reactor system used in this study consisted of glass vessels with
working volumes of 0.5 L (acidogenic) and 2.5 L (methanogenic) respectively. The
acidogenic reactor (RA) was operated under mesophilic conditions (37 2C) and
methanogenic reactor (RM) was operated under thermophilic (53 2C)
conditions.
