Table 1 Extended Weende forage analysis of maize silage and solid digestate after 8 days of acidogenic fermentation

From: Metabolic and microbial community dynamics during the hydrolytic and acidogenic fermentation in a leach-bed process

Parameter Substrate Solid digestate Degree of conversion (%)
Fresh mass (g) 200 230  
TS (%fresh mass) 40.0 20.2 42
VS (%fresh mass) 38.2 18.6 44
TKN (g/kgTS) 10.3 8.9 50
Crude protein (g/kgTS) 64.2 55.9 49
Crude lipid (g/kgTS) 25.9 26.4 41
NfE, including starch (g/kgTS) 659.6 532.6 53
Cellulose (g/kgTS) 185.7 283.5 11
Hemicellulose (g/kgTS) 385.5 356.2 46
  1. TS, total solids; VS, volatile solids; TKN, total Kjeldahl nitrogen; NfE, nitrogen-free extractive. The degrees of conversion were calculated as described in the methods section.
