Duckweed The cultivated duckweed was used to produce value-added chemicals such as glucose, levulinic acid and formic Biomass acid in diluted HCl aqueous solution. A high glucose yield of 93.4% (471 g/kg based on loading duckweed mass) Levulinic acid could be achieved at 180 °C in short reaction time, and the generated glucose was converted into levulinic acid Ethyl levulinate and formic acid with yields of 52.0% and 34.1%, respectively, for 150 min, corresponding to 262 g/kg levulinic Glucose acid yield and 171 g/kg formic acid yield based on the mass of loading duckweed, respectively.
