Hydrolysis of potatoes
VLAČIHOVÁ, Andrea
This work compares acid, alkaline and enzymatic hydrolysis of potato starch with simultaneous application of various pressures (0MPa, 0,3MPa and 1MPa). Acid hydrolysis was made by sulphuric acid of intensity 3, 6, 9 and 12 %, alkaline hydrolysis was made by sodium hydroxide of intensity 3, 6, 9 and 12 % and four enzymatic preparations for starch hydrolysis were used for enzymatic hydrolysis. Hydrolysis effect was measured via GE and added by alcohol yield. There was positive influence of increased pressure 0,3MPa and 1Mpa on hydrolysis process visible in this experiment.

Hydrolysis of corn silage
MÍKA, Václav
Aim work is compare yield GE at acid, alkalic and enzymatic hydrolysis cellulose phytomass at different acidity (H2SO4, 3, 6, 9 and 12%), fundamentals (NaOH, 3, 6, 9 and 12%) and while using different enzymatic preparations (6 preparations to hydrolysis celluloses and hemicelluloses). Further is assessed positive influence compressive extrusion (0,3MPa and 1MPa).
