Abstract

In this study, the long-term stability of biomass and hydrogen production on acetate by Rhodobacter capsulatus YO3 (hup(-)) was investigated. The experiments were performed in fed-batch panel photobioreactors operated under the natural sunlight in Ankara, Turkey. They were carried out between October and December in order to resemble low temperature and low light intensity and between July and August in order to resemble high temperature and high light intensity.
