GSHE (2 mL per 1 kg of raw material dry matter)
and proteolytic (Neutrase 0.8 L, 0.875 mL kg?1 of raw material
dry matter) preparations were added and the total weight of the
slurry was adjusted to 200 g with distilled water resulting in a
raw material loading of 150 g of dry matter per kilogram of fermentation
medium (the experiments were conducted at relatively
low raw material loading because used raw material showed the
high water binding capacity and application of higher substrate
loading resulted in obtaining solid like consistency of the fermentation
medium what was observed earlier
