Background:The ability for hydrogen production of 13 native strains of Clostridium spp. strains isolated from Colombian soil was evaluated using glycerol substrate. Glycerol to hydrogen conversion was investigated using a batch fermentation reactor and industrial glycerol source (50 g.l -1 , pH 7.00). Results:The results were quantified regarding acids, hydrogen, biomass and solvent production. The selected strain gave good hydrogen over production output at 14.4 mmol H2.l -1 , productivity 0.3167 mg H2.h -1 l -1 culture mediumand yield 0.1962 mol H2.mol -1 glycerol. A further fermentation assay a 4.0 liter batch reactor let to being 0.26 mg.l -1 .h -1 after 18 hrs of fermentation. Logistic model, Luedeking-Piret model and Luedeking-Piret modified models were used for modeling changes in cell growth, hydrogen production and substrate consumption (Correlation coefficients R 2 = 0.95 for biomass substrate, R 2 = 0.77 hydrogen production). Conclusions:Our results indicate that hydrogen production through glycerol bioconversion by native strains is possible.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
