Abstract
The massive food wastes are generated from various human activities and the disposal of them become major environmental concerns. The anaerobic fermentations are the promising biological processes which convert renewable resources including food wastes into basic chemicals and liquid fuels. The object of this study is effective production of organic acids and butanol from food waste using Clostridium saccharoperbutylacetonicum N1-4. The commercially supplied dry food waste was pre-hydrolyzed using Viscozyme. In the medium containing 20% (w/v) pre-hydrolyzed food waste, C. saccharoperbutyacetonicum N1-4 exhibited the highest production; butyric acid 7.94 g/L, acetic acid 3.72 g/L and butanol 1.71g/L. To investigate the inhibitory effect of salt in food waste, the batch fermentations using medium containing different concentration of NaCl were performed. C. saccharoperbutyacetonicum N1-4 grows at moderate concentration of NaCl (up to 10 g/L) without inhibition.
