Bioethanol Production from Azolla filiculoides by Saccharomyces cerevisiae, Pichia stipitis, Candida lusitaniae, and Kluyveromyces marxianus.

摘要: Ethanol was produced by separate hydrolysis and fermentation using Azolla filiculoides as a biomass. Thermal acid enzymatic saccharification were used pretreatment methods to produce monosaccharides from Azolla. The optimal content for thermal of 14% (w/v) weed slurry 16.7-g/L 200 mM H2SO4 at 121 °C 60 min. Enzymatic 16 U/mL Viscozyme 61.6 g/L monosaccharide 48 h. productions with ethanol yield coefficients hydrolysate Kluyveromyces marxianus, Candida lusitaniae Saccharomyces cerevisiae, Pichia stipitis 26.8 g/L (YEtOH = 0.43), 23.2 g/L (YEtOH = 0.37), 18.2 g/L (YEtOH = 0.29), 13.7 g/L (YEtOH = 0.22), respectively. cerevisiae produces the lowest it utilized only glucose. Bioethanol can be successfully marxianus because consumed mixture glucose xylose completely within 60 h.
