| Outline of Final Research Achievements |
Duckweed is recognized as alternative feedstock for production of biofuels. In this study, many types of plant growth-promoting bacteria (PGPB) which can increase duckweed growth rate were isolated, and their mechanisms involved in duckweed growth promotion were clarified. PGPB-duckweed cultivation reactors using effluent of a sewage treatment plant produced efficiently duckweed biomass. The biomass production rate was 2-3 times higher than that of normal duckweed cultivation without PGPB. The duckweed biomass showed high ethanol and methane production potentials. The results demonstrate that the use of PGPB in duckweed cultivation can improve the efficiency of duckweed biomass refinery to produce biofuels (ethanol and methane).
