2.5. Analytical methods
The following parameters were analyzed: pH, VFAs, TS, VS, total
C and total N. All samples were analyzed in triplicates. Samples
were centrifuged at 15000 r/min for 20 min, then, the supernatant
was filtered by the 0.45 mm cellulose acetate membrane. After that,
the VFAs were measured according to standard methods (APHA,
2005). The cellulase activity was measured by filter paper enzyme
activity (FPA) method [20].
