Enhanced biohydrogen production by integrating wastewater and photo-fermentation

Abstract

Currently, a great deal of studies is being accomplished on biohydrogen which is produced by biological processes. However, these methods are limited by the low hydrogen yield and the expensive cost of synthetic hydrogen production medium. The best approach to overcome limitations is to apply wastewater as a feedstock for hydrogen production with efficient strategies. This study demonstrated the roles of different strategies such as optimization, feedstock pre-treatment processes and metals supplementation on biohydrogen production.
