Duckweed (Lemna minor) was grown in swine lagoon wastewater and Schenk & Hildebrandt medium with a growth rate of 3.5 and 14.1 g m(-2)day(-1) (dry basis), respectively detected. The rapid accumulation of starch in duckweed biomass (10-36%, w/w) was triggered by nutrient starvation or growing in dark with addition of glucose. The harvested duckweed biomass (from culture in wastewater) contained 20.3% (w/w) total glucan, 32.3% (w/w) proteins, trace hemicellulose and undetectable lignin. Without prior thermal-chemical pretreatment, up to 96.2% (w/w) of glucose could be enzymatically released from both the cellulose and starch fractions of duckweed biomass. The enzymatic hydrolysates could be efficiently fermented by two yeast strains (self-flocculating yeast SPSC01 and conventional yeast ATCC 24859) with a high ethanol yield of 0.485 g g(-1) (glucose).
