Enhanced methane production from cellulose using a two-stage process involving a bioelectrochemical system and a fixed film reactor

Table 1 Operating conditions used for different two-stage processes

Reactor type	HRT (days)	pH_in	Aim
BES → FFR	4.0 → 8.3	6.1 → 7.5	Acclimation for 17 days
BES → FFR	2.5 → 4.2	6.1 → 7.5	Comparison after 13 days
NBES → FFR	4.0 → 8.3	6.1 → 7.5	Acclimation for 17 days
NBES → FFR	2.5 → 4.2	6.1 → 7.5	Comparison after 13 days
BES → NFFR	4.0 → 8.3	6.1 → 7.5	Acclimation for 17 days
BES → NFFR	2.5 → 4.2	6.1 → 7.5	Comparison after 13 days

NBES did not contain an electrochemical system. The FFR contained CFTs, whereas the NFFR did not contain CFTs
