Solubilization and conversion of poplar by engineered C. bescii. Greenhouse-grown poplar trees were harvested at 6 months, debarked, air dried, and prepared without further processing as approximately 0.5-cm diameter stem segments. A portion of the stem material was milled and sieved to 40/80 mesh size (0.18-0.42 mm), water washed, dried at 50 °C and used at 5 g/L loading. Further stem segments were cut to a weight of 0.25–0.30 g and used directly in experiments. Solid bars represent milled biomass, hatched bars represent poplar stem segments. a Total biomass solubilization. b Total carbohydrate solubilization. c C. bescii (MACB 1058) fermentation products resulting from 5 g/L substrate loading. Error bars represent one standard error of three biological replicates. Source data are provided as a Source Data file
