Cumulative CO 2 production. Plotting of cumulative carbon dioxide production from start of activity to the selected end-point cut-off for equally-sized Whatman paper chads. The sigmoid-shaped curves are in agreement with previously described logistic (or Richards) models of solid cellulose conversion through microbial activity.
