BIOETHANOL PRODUCTION FROM BIOMASSES OF FRESH WATER BLOOMS - SPIROGYRA SP. AND EICHHORNIA CRASSIPES BY SACCHAROMYCES CEREVISIAE
*Nisha K. Raju and Noufal N.
In this study, we explored efficiency of Saccharomyces cerevisiae the fermentative microflora for biological pretreatment of Spirigyra sp., and Eichhornia crassipes to fermentable sugar and fermentation of both glucose and xylose to ethanol to increase ethanol yield. The technique herein provides cost effective process to get economically important product from it and more or less helps in lowering plant. The isolated fungi appear as unicellular, large spherical individual cells and taken crystal violet and appeared purple in colour. The fungal cells taken up lactophenol cotton blue stain and appeared blue colour spherical to oval structure.Some of the cells also showed bud formation. Gas formation observed in media inoculated yeast. No gas formation observed in control tube. Colour of the media also turned from red to yellow in colour.
Keywords: Algal bloom, bioethanol, fungus and fermentation.
