Grass hay is one of assailable cellulose containing non-food agricultural wastes that can be used as a carbohydrate source by microorganisms producing biofuels. In this study three Clostridium strains Clostridium acetobutylicum, Clostridium beijerinckii and Clostridium tetanomorphum, capable of producing acetone, butanol and ethanol (ABE) were adapted to convert enzymatically hydrolyzed hay used as a growth media additive. The results of growth curves, substrate degradation kinetics and FT-IR analyses of bacterial biomass macromolecular composition showed diverse strain-specific cell response to the growth medium composition.
• Three Clostridium strains were adapted to convert enzymatically hydrolyzed hay. • FT-IR analysis showed changes in the macromolecular composition of clostridia in response to the growth medium. • FT-IR analysis is suitable for characterization of clostridia during the adaption.
