Table 3 Degradation (%) of cellulose and hemicellulose of the mixtures following solid-state anaerobic digestion

From: Using the properties of soil to speed up the start-up process, enhance process stability, and improve the methane content and yield of solid-state anaerobic digestion of alkaline-pretreated poplar processing residues

Parameter   Control 5 : 1 2.5 : 1 1 : 1
TS Pretreatment 41.0 ± 7.1 50.1 ± 7.5 52.6 ± 1.7 13.6 ± 2.2
  No pretreatment 44.3 ± 2.2 45.8 ± 6.5 32.1 ± 3.8 44.7 ± 1.5
VS Pretreatment 21.3 ± 1.0 26.4 ± 1.6 42.9 ± 7.1 7.8 ± 0.2
  No pretreatment 25.8 ± 3.9 42.5 ± 1.3 38.7 ± 2.1 13.8 ± 3.1
  1. Note: Degradation (%) of cellulose and hemicellulose were calculated after determination of the TS and VS contents of mixtures before and after anaerobic codigestion.
  2. TS: total solids; VS: volatile solids.
