Abstract

Hydrogen is a renewable source of energy and is effective. Hydrogen can be produced by photofermentation by purple non sulfur bacteria such as Rhodobacter sphaeroides, due to the high ability to produce hydrogen in anaerobic conditions. In this study, bacteria were incubated in 100 mL serum bottles in anaerobic conditions. The aims of this study were to maximize the hydro gen production of Rhodobacter sphaeroides NCIMB 8253 which involves the study of the inoculums in aerobic and anaerobic conditions, and to determine the effect of initial pH and the effect of light intensity on hydrogen production. From the experiments, it was found that inoculums in anaerobic conditions produced the highest of hydrogen yield 220.5 mL/g substrate. pH 7 is the most suitable pH for the hydrogen production. Light intensity of 5,000 lux is the optimum value that would give the highest hydrogen production at 80.21 mL and hydrogen yield 401.04 mL/g substrate. Hydrogen production declined at light intensities higher than 5,000 lux.
