Abstract:

The present study focuses on bioethanol production from cotton stalk hydrolysate using immobilized cell fermentation. For this, cotton stalk was hydrolyzed by two stage acid treatment, and the obtained hydrolysate was detoxified and fermented using immobilized co culture of SaccharomycescerevisiaeMTCC36 and PachysolentannophilusMTCC1077.The results showed that, maximum ethanol concentration of 3.94 g/L was achieved after 36 hours of fermentation by consuming 90.18% of total available sugar, with a corresponding yield of 0.142 g/g biomass, 0.221 g/g of holocelluloses, 0.355 g/g of fermentable sugar, and fermentation efficiency of 69.53% respectively. As recycling of immobilized cell is concern, the first two batches gave significantly similar results in concentration, yield and fermentation efficiency, while during third cycle of fermentation, beads became disintegrated.


Keywords: Fermentation, Bioethanol, Cotton stalk, Saccharomyces cerevisiae, Pachysolen tannophilus, Immobilization.
