CO 2 production on different substrate types. Changes in the rates of carbon dioxide production were compared for same-sized (6600 mm2) chads of Whatman paper #1, #598 and #3. Plots are staggered on the x-axis and the corresponding mean mass of each chad type labeled; the black dotted lines denote the cut-off points set for the start of growth and the end-point fermentation.
