Anaerobic digestion is a promising technology for kitchen waste treatment, as it has high energy recovery and reduces environmental problems. A two-compartment bioreactor (TCR) constructed with a hydrogen compartment and a methane compartment with the working volume of 300 mL and 4700 mL respectively was cultivated at various kitchen waste from 10 to 80 g COD/L at hydraulic retention time 2 d to characterize the biohythane production performance. Results show biohythane composition H2, CH4 and CO2 were 0-9%, 35-48%, and 48-58%, respectively during steady-state conditions. After 80 days of cultivation, Firmicutes dominated the hydrogen compartment and Methanobacteriaceae and Methanomicrobiaceae dominated the methane compartment.

“…On the other hand, the limitations of dark fermentation are its low yield due to the formation of by-products like alcohol and volatile fatty acids (Pandu and Joseph, 2012). Recently, Lay et al (2019) developed a new biologic method where they used the recycled rice husk as the support carrier thereby enriching the biohydrogen production with subsequent higher yield of about 200 ml/l. Khanna and Das, (2012) have said that biohydrogen production takes place in two catabolic steps, which are decarboxylation of pyruvate into acetyl CoA which generates the reduced ferrodoxin which in turn acts as the electron donor for hydrogenase, the hydrogen catalyzing enzyme in organisms such as in Clostridium sp (Eq 1 and 2).…”

Hydrogen is the lightest element and is an excellent energy carrier due to high energy intensity. Hydrogen can be produced in a number of ways like physical, chemical and biological methods. Since the physical and chemical method of hydrogen production is energy intensive, research is currently concentrated on the biological methods. Among the biological method dark fermentation has gained greater attention because of its independence to light and the ability to use various substrates for fermentation. In this review, there is detailed information about biohydrogen production by dark fermentation using microorganisms including, the hydrogen producing anaerobic and facultative anaerobic bacteria, the enzymes involved, the factors affecting the process such as temperature, pH, substrates, hydraulic retention time and hydrogen partial pressure. Also a brief discussion about the metabolic engineering aspects in biohydrogen production and a note on microbial electrolysis cell has been discussed.
