摘要： Disclosed is a method for producing ethanol, including: culturing yeast transformed so as to display an enzyme on the cell surface in a medium containing particles of lignocellulosic biomass, thereby producing ethanol, wherein the enzyme is an enzyme involved in hydrolysis of the lignocellulosic biomass. The present invention makes it possible to provide a method for producing ethanol by which a high ethanol yield can be achieved from lignocellulosic biomass with lower initial cell concentration and added enzyme amount.

摘要： A method for producing a fatty acid ester according to the present invention includes mixing a raw fat or oil, a liquid enzyme, and an alcohol having 1 to 8 carbon atoms in the presence of water and an electrolyte. According to the present invention, a fatty acid ester can be efficiently produced via a transesterification reaction without using any expensive buffer solution or amphipathic substance. Furthermore, in the reaction, it is not necessarily required to agitate reactants at a high speed, which makes the present invention adaptive to various production facilities and conditions.
