Special Issue Information

Dear Colleagues,

Fermentative hydrogen production from different waste materials is a promising approach to produce bio-energy in terms of renewable energy exploration, which is under extensive investigation worldwide. A wide variety of organic wastes can be used as feedstock for hydrogen production in fermentation, thus providing an added advantage to waste recycling. However, the process of fermentation is essentially restricted by the low yields of hydrogen, and so advancements are still necessary. Extensive research has been conducted to overcome such bottlenecks. Various technologies have been used to improve the fermentative hydrogen yield, including bacterial strain, substrate, reactor design, metabolic engineering, and two-stage processes; the pretreatment of the seed sludge; the optimization of the bioprocess parameters (e.g., temperature, pH, organic loading rate, hydraulic retention time, effluent recycling ratio, nitrogen, phosphate, metal ion), etc.

The goal of this Special Issue is to publish recent and innovative research results, as well as review papers, on fermentative hydrogen production. Review and research papers on microbiology, biochemistry, and enzymology for fermentative hydrogen production are also of interest. If you would like to contribute a review paper, please contact one of the editors to discuss the topic's relevance before submitting the manuscript.

The ability of Parageobacillus thermoglucosidasius to produce H2 from CO via the water–gas shift (WGS) reaction makes it a compelling microorganism for biofuels research. Optimizing this process requires evaluating parameters such as pressure. This study aimed to understand how H2 production is affected by increasing CO, N2, and H2 partial pressures to 1.0, 2.0, and 3.0 bar. Increasing CO partial pressure can improve the solubility of the gas in the liquid phase. However, raising CO partial pressure to 3.0 bar had an inhibitory effect, delaying and reducing H2 production. By contrast, increasing N2 and H2 partial pressures to 3.0 bar had positive effects, reaching a H2 production of 9.2 mmol and 130 mmol, respectively. Analysis of the electron balance at the end of the fermentation process showed that the selectivity toward H2 production reached 95%, with the remainder of electrons deriving from CO and glucose directed at organic acid production, mainly acetate, followed by formate.
