Influence of Iron for the Acetone-Butanol Fermentation on the Sucrose and Molasses Media

Part 2. The Influence for the Butanol Fermentation Organisms

Abstract

1. The inhibiting substance which decrease the acetone yield was produced by cooking of molasses with iron and ferrous salts.
2. The cultivation of organisms could be reduced the inhibitance.
3. It was found that organisms selected through colonies from one strain exhibited the difference of resistance against the inhibition.
4. The difference of resistance in one strain to the inhibition were considerably fixed genetically.
