enzyme treatments can be attributed to kBMP being a function of
total biomethane potential yield. Hence the simultaneous increase
in final biomethane potential yield, caused by enzyme addition,
meant that the observed improvement to biomethane production
was undetectable using Eq. (1). Given this, it was concluded that
to detect significant changes in rates of biomethane production
within the current data set, the additional sensitivity achieved by
studying the three digestion time-points was crucial.
