strains isolated from Colombian soil was evaluated using glycerol substrate.
Glycerol to hydrogen conversion -1 was investigated using a batch fermentation reactor and industrial glycerol source (50 g.l , pH 7.00). Results: The results were quantified regarding acids, hydrogen, biomass and solvent production.
The -1 selected strain gave good hydrogen over production output at 14.4 mm...
