Abstract
The invention relates to a cellulose solution manufacturing method including: performing an ozonation treatment to bring a cellulose-containing material and ozone into contact with each other; and performing an alkali treatment to bring the obtained treated material and an alkali aqueous solution into contact with each other, thereby dissolving at least cellulose in the cellulose-containing material brought into contact with the ozone in the alkali aqueous solution. According to the invention, it is possible to provide a method of manufacturing a cellulose solution in which cellulose can be dissolved in a more simple manner, a method of manufacturing a cellulose precipitate in which cellulose can be recovered from the cellulose solution, and a method of saccharifying cellulose which uses the cellulose precipitate.
