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

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

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/kg_TS)	10.3	8.9	50
Crude protein (g/kg_TS)	64.2	55.9	49
Crude lipid (g/kg_TS)	25.9	26.4	41
NfE, including starch (g/kg_TS)	659.6	532.6	53
Cellulose (g/kg_TS)	185.7	283.5	11
Hemicellulose (g/kg_TS)	385.5	356.2	46

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.
