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 R2 = 0.95 for biomass substrate, R2 = 0.77 hydrogen production).application/pdfAtribución-NoComercial-CompartirIgual 2.5 Colombiahttp://creativecommons.org/licenses/by-nc-sa/2.5/co/Evaluating Colombian Clostridium spp. strains’ hydrogen production using glycerol as substrateAnaerobic fermentationBiofuelClostridium spp.GlycerolHydrogenMathematical modehttps://doi.org/10.2225/vol16-issue2-fulltext-4Generación de Nuevo Conocimiento: Artículos publicados en revistas especializadas - Electrónicos
