Madhuca Longifolia Flowers for High Yields of Bio-Ethanol Feedstock Production

Ravi Gedela, Ravi Teja Naidu, Srinivasao Rachakonda, Asiri Naidu


Fermentation process, the production of bio-ethanol from Madhuca longifolia (Mahua) flowers by using Saccharomyces cerevisiae (Mahua flowers, collected from Eastern Ghats region of Andhra Pradesh, India). The evaluated results showed that, 1000 ml of acidic fermented media at pH-4, 5 and 5.7, produced the average quantity of bio-ethanol in test-1 (S.cerevisiae + Mahua flowers + Media), test -2 (Mahua flowers + Media) and control (media) ≈ 170.03 ml, ≈ 142.3 ml and ≈ 127.7 ml respectively. The percentage of bio-ethanol was confirmation by using Alcohol meter, the analysis results showed that in test-1, test-2 and control ≈ 46.6 %, ≈ 24.6 % and ≈ 0% respectively. The presence of bio-ethanol were verified by using Spectrophotometer at 204-240 nm.
