A, B Ethanol production, glucose consumption, optical density (OD) at 600 nm, and pH at 35 ℃ with 200 g/L glucose, (C, D) ethanol production, glucose consumption, optical density (OD) at 600 nm, and pH at 35 ℃ with 260 g/L glucose, (E, F) ethanol production, glucose consumption, optical density (OD) at 600 nm, and pH at 37 ℃ with 200 g/L glucose, (G, H) ethanol production and pH at 35 ℃ and corn mash as a carbon source. I The counts of S. cerevisiae 1308, 1308-FLO5, and 1308-FLO10 cells that were adsorbed on 1 g of dry cotton fibers after biofilm-immobilized continuous fermentation in the 2-L column reactor
