ABSTRACT

Fermentation is the most beneficial process for hydrogen (H2) production. The previous studies were mostly focused on medium, microorganisms, pH control, temperature, and hydraulic retention time. In this study, we used electric current to measure the H2 production rate and its concentration. We observed the microorganism morphology to determine the effect of electric current on the microorganism growth state. The results showed the range of H2 production rate and its concentration were 1,200−1,350 mL/L∙hr and 32−42% with the current of 1.05−3.66 mA/cm2. H2 concentration decreased to 2.09 mA/cm2. However, with the shorter rod-shaped microorganisms, the production time was shorter than the original strain.
