The effects of carbon-nitrogen mass ratio (C/N) on growth and hydrogen production were examined by batch culture with a strain of fermentative hydrogen producing bacterium Rennanqilyf3. The research shows that the concentration of nitrogen resource has the big effects on hydrogen production of Rennanqilyf3. The optimum C/N of the growth and hydrogen production in Rennanqilyf3 was 3.3. The liquid end products were mainly ethanol and (acetate.) When C/N was 3.3, glucose depredating efficiency was the highest. With increase of organics, final pH value changed a little. C/N is one of important engineering parameters for fermentative hydrogen production, with the best C/N of 3.0—3.5.
