Abstract

Hydrogen energy represents a source of clean and sustainable energy future. Process of hydrogen production by fermentative bacteria brings a new hope to the world's energy industry. In present study, some bacterial strains having potentiality of hydrogen production were isolated from cattle dungs in Vietnam. Amongst, Gram-negative bacterial strain Tr2 was selected since its capacity of hydrogen production was the highest. Various environmental factors (pre-culture age, inoculum ratio, carbon source, nitrogen source, iron, sodium chloride, temperature and pH) did affect the growth and hydrogen production of strain Tr2. Optimal conditions for its growth and hydrogen production consisted of age of pre-culture (in the middle of logarit phase), inoculum ratio (10 % v/v), glucose (10 g/l), yeast extract (3 g/l), FeSO4.7H2O (100 mg/l), pH 6,5 at 30 oC. Obtained results showed the high potentiality of strain Tr2 in application to dark fermentation for biohydrogen production by native bacteria in Vietnam
