Liquid biofuels,such as bioethanol,converted from biomass are considered as a promising alternative for traditional fossil fuels.However,existing bioethanol production modes have some inherent problems,including the adverse impacts on food security,environment and insufficient agricultural land.As a new bioethanol production feedstock,duckweed has a longer yearly production period than most of other plants.It can thrive on eutrophic wastewater,and accumulate high starch percentage.In our study,we found that the starch percentage of duckweed accumulated from the original 3.0%to 45.8%(dry matter)in 5 days when grown in distilled water.Activity of key enzymes involved in starch biosynthesis were up-regulated and enzymes involved in starch degradation were down-regulated significantly.
