Abstract
A simplified method is described for the production of butanol and acetone. The acid mixture (H/sub 3/PO/sub 4/, 10 to 20%; H/sub 2/SO/sub 4/, 90 to 80%) used to hydrolyze corn cobs and other vegetable waste products served also to invert the sugar of molasses which was added in 3 parts to 1 part hydrolyzate on the basis of reducing sugar content. The mixture was then diluted and neutralized with NH/sub 4/OH to pH 6.3 to 6.8. In this way a suitable hydrolyzate medium containing the appropriate amounts of mineral salts as well as invert sugar was provided for fermentation by Clostridium butyricum Prazmowsky. Lignin which precipitated during hydrolysis served as a solid phase which helped to accelerate fermentation. Combined yields of butanol, acetone, and small amounts of ethanol amounted to 30 to 38% of the available sugar; approximately 67% consisted of butanol.
