This study presents bioconversion of water hyacinth (<i>Eichhornia crassipes</i>) to bioethanol using two-sequential steps of acid hydrolysis (10% sulfuric acid) and yeast (<i>Candida intermedia</i>) fermentation. Maximum ethanol yield co-efficient was comparable to those obtained through enzymatic saccharification and fermentation of acid hydrolysate using fully equipped fermentor. A maximum ethanol yield (coefficient, 0.21 g g<sup>-1</sup>; productivity, 0.010 g l<sup>-1</sup>h<sup>-1</sup>) was comparable to predicted value (0.23 g g<sup>-1</sup>) obtained by CCD (Central Composite Design). Two colorimetric methods (phloroglucinol and dichromate assays) were used for determination of xylose and ethanol using UV-Vis spectrophotometer. Although maximum ethanol concentration was low, an economically efficient overall process was carried out to convert a lignocellulosic biomass to bioethanol. |
