Acetate* produced (mmol g^-1 VS)	7.2	4.5	5.3	4.3	5.4	2.9	2.8	6.5
Calculated methane yield from acetate (litres g^-1 VS)	0.161	0.101	0.120	0.097	0.122	0.066	0.064	0.145
Calculated total methane yield (litres g^-1 VS)	0.185	0.118	0.177	0.130	0.199	0.167	0.160	0.253

*acetate produced is the mean cumulative amount over four weeks from triplicate single-stage fermenters. The total methane yield is the calculated methane yield from acetate added to the actual methane produced in the same fermenter over four weeks.
