Optimization of Simple Sugars and Process pH for Effective Biohydrogen Production Using <em>Enterobacter</em> <em>Aerogens</em>: An Experimental Study

Abstract

This communication presents the potential of process parameters including simple sugars and pH for biohydrogen production using facultative anaerobic bacteria <em>Enterobacter aerogens</em>. The obtained data was fit in the modified Gompertz equation and the regression coefficient (R²) was found in the range of 0.998 which provides a strong correlation between the experimental data and the curve fit. The study revealed that glucose is the most compatible and cost effective substrate for biohydrogen production having yield of 0.87mol H₂/mol of glucose consumed. It is also found that there is a strong possibility to use sugar based organic residues from industrial substrates and wastewater for clean energy products which are cost effective and environmental friendly.
