In this study we evaluated biohydrogen production potential as operational parameters (substrate, salt concentration, and temperature) using eight inoculum sources. While the volumetric biohydrogen production rate was significantly affected by temperature and inoculum sources, substrate and salt concentration did not have a significant effect on the biohydrogen production. Mesophilic temperature (37℃) was also found more appropriate for the hydrogen production than thermophilic temperature (50℃). Rate, while the eight inoculum sources, anaerobic digestion sludge exhibited the fastest biohydrogen production. The maximum production rate from anaerobic digestion sludge was 2,729 and 1,385 ml-H2·l-1·d-1 at mesophilic and thermophilic temperature, respectively.
