| Abstract: | Hydrogen
production, using defined microbial consortia, can not only effectively utilize
various complex organic wastes to solve the environmental pollution problem but
also the energy crisis to some extent. Defined consortia comprising of Enterobacter
cloacae IIT BT08, Bacillus coagulans IIT BT S1 and Citrobacter
freundii IIT BT L139 in the ratio 2:1:1 was found suitable to utilize
molasses (a by-product of sugar industry), and produced 16.66 mole H2/kg COD
reduced. Hydrogen yield, using consortia, was found to be more as compared to
that obtained from the strains individually. Three physico-chemical parameters
namely pH, substrate concentration and temperature were optimized to
obtain maximum hydrogen yield. The most suitable experimental conditions for
maximum production of hydrogen with respect to substrate concentration, pH
and temperature were found to be 16.5 g/L, 7.5 and 35°C, respectively and that
of theoretically optimized values were 16.5 g/L, 7.5 and 32.5°C, respectively. |
