An alcohol production system that produces alcohol by alcoholic fermentation using a saccharide solution, including an alcoholic fermentation vessel in which the saccharide solution is fermented by adding yeast to produce alcohol, which is an organic feedstock, and a biomass-hydrothermally-treated-product adding means that adds a biomass hydrothermally-treated product obtained by hydrothermally treating a biomass feedstock to the alcoholic fermentation vessel. The alcohol production system can improve alcoholic fermentation efficiency and realize cost reduction without adding only a mineral salt from outside.

Fermentation system and fermentation method using saccharide solution

A saccharide-solution producing apparatusA according to the present invention is a saccharide-solution producing apparatus for producing a saccharide solutionderived from a carbohydrate-based material, and includes a saccharide-solution controlling unitA that controls the saccharide solution derived from the carbohydrate-based material, a cellulosic biomass saccharifying unitthat saccharifies hydrothermally treated biomass obtained by hydrothermally decomposing a cellulosic biomass materialthat contains a lignin component and a hemicellulose component, and produces a diluted saccharide solution, and a diluted-saccharide-solution supply pipe Lthat mixes the diluted saccharide solutionproduced by the cellulosic biomass saccharifying unitinto the saccharide-solution controlling unitA. With this configuration, it is possible to improve production efficiency of the saccharide solutionand to realize cost reduction.
