Kinetic analysis of fermentative hydrogen production by Clostridium pasteurianum under static magnetic field

Year: 2025

Type: article

Abstract: Many studies focus on optimizing the dark fermentative biohydrogen production. In the present work, static magnetic field (SMF) S pole and N pole were applied to the dark fermentation system of Clostridium pasteurianum to evaluate the effect of magnetic field direction on biohydrogen production process of Clostridium pasteurianum . The experimental results showed that the magnetic S pole application was more effective than the magnetic N pole application in improving microbial hydrogen production progress parameters. The maximum hydrogen production 2.47 ± 0.010 mol H 2 /mol glucose was achieved in the magnetic S pole application group. Meanwhile, the maximum biomass, carbon conversion efficiency and energy conversion efficiency in magnetic S pole application group were increased by 93%, 27.7% and 28.3%, respectively, compared with the control group. The results provided a new information for further exploring the application of magnetic field in dark fermentative biohydrogen production process.
