ABSTRACT
The main requirement for efficient H2 production is the availability of efficient microbial consortia in which H2-utilizing and non-H2-producing bacteria are suppressed. This study evaluates the H2 production potentials from sewage sludge with and without pretreated anaerobic culture used as inoculum. Three different anaerobic cultures (mixed anaerobic sludge from CSTR tank reactor, fermented manure, and heat-treated fermented manure) were used as inoculum. Due to hydrolysis during heat treatment, organic matter concentration increased during fermentation. Compared to other operating conditions, heat-treated fermented manure as inoculum and sewage sludge as the substrate mixture had the highest hydrogen production. The results showed that heat pretreatment of inoculum should increase H2 production potential.
