The concentrations of these components were optimized using Central Composite Design (CCD) and were found to be:  glucose, 19.25g/L; peptone, 5.64g/L; malt extract, 1.64g/L; yeast extract, 3.16g/L and NaCl, 4.312g/L. For further maximizing the production of hydrogen, the process parameters including pH, temperature and fermentation time were optimized by adopting Box-Behnken design. A maximum hydrogen yield of 0.91 mol H2/mol substrate was achieved under the optimum conditions of pH, 7.0; temperature, 34.5oC and fermentation time, 42.5h.
