| Outline of Final Research Achievements |
Glycerol becomes alternative and attractive feedstock for chemical production due to rapid increase of biodiesel fuel utilization. Some acetic acid bacteria are known to produce large amount of D-glyceric acid from glycerol. However, raw glycerol derived from biodiesel fuel production contains impurities like methanol, which would cause a sever decrease in yield of glyceric acid. In this study, enentioselective oxidation of glycerol derived from biodiesel fuel production was investigated by using a methanol-assimilating acetic acid bacterium. Application of glyceric acid to functional chemicals was also investigated.
The methylotrophic acetic acid bacterium used in this study could produce larger amount of glyceric acid from glycerol in the presence of methanol than that in the absence of methanol. Also, glyceric acid was successfully converted to amphihilic compounds, and these compounds showed superior amphipathic properties compared with those of commercial detergents.
