Abstract
Microalgal (Micractinium reisseri YSW05) photo-heterotrophic hydrogen production was investigated with using volatile fatty acids (acetate and butyrate) from dark-fermentation effluent. Dilution ratio (effluent: deionized water) of 1:0 at pH 8.0 supported the maximum hydrogen and biomass production, and the highest acetate and butyrate consumption. Microalgal hydrogen production was higher with continuous light condition compared to alternating dark/light cycle. Hydrogen production correlated with both, biomass production and hydrogenase activity under all experimental conditions. Hydrogenase activity and apparent hydrogen production decreased significantly with increasing headspace oxygen. Interestingly substantial hydrogenase activity was observed at almost atmospheric partial pressure of oxygen (19%), indicating that the enzyme could be oxygen tolerant. The present study demonstrated the application of conventional microbial fermentation effluent for microalgae cultivation and hydrogen production, and showed the presence of oxygen tolerant hydrogenase in M. reisseri which might help to establish a novel strategy for biohydrogen technology in atmospheric condition.
