摘要:
The present invention provides a method for producing a useful substance efficiently from cellulose without using any cellulase preparation. According to the disclosures of the present specification, in the production of a useful substance from a cellulose-containing material, the cellulose-containing material is brought into contact with an ionic liquid to cause the ionic liquid to permeate the cellulose-containing material, and a carbon source comprising the cellulose in the cellulose-containing material is simultaneously saccharified and fermented by a cellulase-producing microorganism in the presence of the ionic liquid.

摘要:
Plant biomass is immersed in a solution that contains a polar solvent and an imidazolium salt that has a melting point of at least 100° C. As a result, the cellulose and hemicellulose present in the plant biomass are relaxed (decrystallized and depolymerized) and brought into an easy-to-degrade state. Reacting the immersed plant biomass with a cellulase produces saccharide at a high conversion efficiency.

A high-voltage generating circuit includes a high-voltage production circuit, a high-voltage detecting circuit, and a control circuit. The high-voltage detecting circuit has a high-voltage circuit section to which a voltage of 1 kV to several tens of kilovolts is applied and a low-voltage circuit section to which a voltage of several tens of volts is applied. In the high-voltage circuit section, a parallel circuit formed of a first voltage-dividing resistor and a part of a second voltage-dividing resistor and a speed-up capacitor, and another parallel circuit formed of the remaining part of the second voltage-dividing resistor and a third voltage-dividing resistor and another speed-up capacitor are connected in series to form a two-stage parallel circuit.
