Abstract

Biohydrogen production by dark fermentation of different waste materials is a promising approach
to produce bio-energy in terms of renewable energy exploration. This communication has reviewed various influencing factors of dark fermentation process with detailed account of determinants in biohydrogen production. It has also focused on different factors such as improved bacterial strain, reactor design, metabolic engineering and two stage processes to enhance the bioenergy productivity from substrate. The study also suggest that complete utilization of
substrates for biological hydrogen production requires the concentrated research and development for efficient functioning of microorganism with integrated application for energy production and bioremediation.
Various studies have been taken into account here, to show the comparative efficiency of different
substrates and operating conditions with inhibitory factors and pretreatment option for biohydrogen production. The study reveals that an extensive research is needed to observe field efficiency of process using low cost substrates and integration
of dark and photo fermentation process. Integrated approach of fermentation process will surely compete with conventional hydrogen process and replace it
completely in future.
