Effects Of Nitrogen Resources On Fermentative Biohydrogen Production Of Biohydrogenbacterium R3 Sp.Nov.

This study discussed the effects of nitrogen resources (include organic nitrogen resources and inorganic nitrogen resources) on hydrogen production bacterium (HPB) Biohydrogenbacterium R3 sp.nov. The performance of organic nitrogen resource to Biohydrogenbacterium R3 sp.nov. was better than that of inorganic nitrogen resource on cell growth and hydrogen production. Yeast powder was most beneficial to promote cell growth and hydrogen production among all those nitrogen resources with the maximum of hydrogen production yield, hydrogen production ration and specific hydrogen produce ration were 1529.69 ml H-2/L, 16.94 mmol H-2/g CDW.h and 1.33 mol H-2/mol glucose, respectively.
