The utilization of acid-tolerant bacteria on ethanol production from kitchen garbage

---

Abstract
In order to achieve ethanol production from kitchen garbage under non-sterilized fermentation, the acidtolerant Zymomonas mobilis named GZNS1 was selected and applied in the fermentation system. Ethanol
production from kitchen garbage under non-sterilized fermentation with GZNS1 was proved to be
feasible. The utilization of control strain and acid-tolerant strain under different conditions demonstrated
that the sequence of ethanol yield was followed: sterilized garbage with control strain inoculated
under pH of 6 (52 g/L)zsterilized garbage with GZNS1 inoculated under pH of 4 (48 g/L) > non-sterilized
garbage with GZNS1 inoculated under pH of 4 (46 g/L). Furthermore, the distillery waste during
fermentation was adopted to recycle fermentation and acquired 50 g/L ethanol, higher than those
adjusted with tap water. The utilization of acid-tolerant bacteria combing with the utilization of distillery
waste associated with the process can increase ethanol production, save energy and reduce the cost of
ethanol production.
