Hydrogen Production by Enterobacter Cloacae Via Dark Fermentation Using an Agro-Industrial Residue, The Cashew Apple Bagasse

Short Introductive summary

In this study, applying the concept of biorefinery, different fractions resulting from the hydrolysis of cashew apple bagasse was evaluated as feedstock in the hydrogen production by Enterobacter cloacae via dark fermentation. The cashew apple bagasse (CAB) is a by-product obtained from the processing of cashew juice and nut. The highest cumulative of the H2 was 1274.7 mL per L of hydrolysate obtained of the enzymatic hydrolysis from CAB (CAB-HE). The use of agro-industrial waste, such as CAB, in the production of biohydrogen represents an innovative approach aligned with the guidelines of the Sustainable Development Goals (SDG). The presented results may contribute to development of H2 production through bioprocesses, presenting yet another raw material, and to achieve global objectives related to climate change mitigation and preservation of natural resources.
