In this study, the feasibility of biohydrogen production from enzymatic hydrolysis of food waste was investigated. Food waste (solid-to-liquid ratio of 10%, w/v) was first hydrolyzed by commercial glucoamylase to release glucose (24.35 g/L) in the food waste hydrolysate. Then, the obtained food waste hydrolysate was used as substrate for biohydrogen production in the batch and continuous (conti...

Halanaerobium hydrogenoformans is an alkaliphilic bacterium capable of biohydrogen production at pH 11 and 7% (wt/vol) salt. We present the 2.6-Mb genome sequence to provide insights into its physiology and potential for bioenergy applications.

Biohydrogen is emerging as a promising carbon-neutral and sustainable energy carrier with high yield to replace conventional fossil fuels. However, biohydrogen commercial uptake mainly hindered by the supply side. As result, various operating parameters must be optimized realize on large-scale. Recently, machine learning algorithms have demonstrated ability handle large amounts of data while re...

Biohydrogen production technology is an emerging field for the advanced wastewater treatment with cogeneration of energy. Besides, hydrogen is an excellent candidate with high energy value (122 kJ/g) than other known carbon‐based fuels with no adverse effects to the environment as it releases only water vapor as the by‐products during the combustion. Biohydrogen production technology can be ass...

BACKGROUND Biohythane production via two-stage fermentation is a promising direction for sustainable energy recovery from lignocellulosic biomass. However, the utilization of lignocellulosic biomass suffers from specific natural recalcitrance. Hydrothermal liquefaction (HTL) is an emerging technology for the liquefaction of biomass, but there are still several challenges for the coupling of HTL...
