Summary: This study evaluates biohydrogen yield efficiency using 26 new DEA models with 55 experiments categorized into DF, PF, and DF-PF technologies, finding that DF-PF has the highest efficiency. Statistical tests show that all biohydrogen inputs and outputs significantly influence yield efficiency. India and Japan are the top two economies benefitting from improved biohydrogen yield efficiency, which can contribute to macroeconomic growth and renewable hydrogen development.

Summary: This study enhanced hydrogen production from water hyacinth by combining ultrasonic-assisted alkaline pretreatment, dark fermentation, and microbial electrolysis cell. The results showed significant improvements in H-2 production with UAA pretreatment, but high concentrations of metabolite products and suspended solid in DF effluent affected the MEC stage's efficiency. The highest H-2 yield was achieved with a WH concentration of 5 g-TS/L.

Summary: The study demonstrates the feasibility of a two-phase biorefinery process applied to waste substrates for producing ethanol rich effluents. It involves dark fermentation followed by photo fermentation to optimize hydrogen production from waste biomass. Using winery wastewater as feedstock, no additional treatments are required, and good hydrogen production results are obtained during the photo fermentative stage.

Summary: The performance of a microbial electrolysis cell (MEC) fed with dark fermentation effluent (DEF) from water hyacinth (WH) was improved by optimizing the auxiliary processes. The optimal conditions for maximizing H-2 production yield and energy efficiency of the MEC were determined to be a 2.2-fold dilution of centrifuged-DFE (approximately 1.64 g of soluble metabolite products per L), a buffer concentration of 75 mM, and an applied voltage of 0.7 V. Under these optimized conditions, the H-2 yield and electrical energy recovery significantly improved compared to unoptimized conditions.

Summary: This study developed a model to predict the production of hydrogen and soluble metabolite products from water hyacinth through dark fermentation. The model accounted for the two forms of substrate (soluble and particulate) and the two stages (hydrolysis and acidogenesis) in the dark fermentation process. The hydrolysis of soluble and particulate forms was described using modified Michaelis-Menten and surface-limiting models, respectively, while the acidogenesis stage was modeled using a multi-substrate-single-biomass model. The model integrated the effects of temperature, pH, and substrate concentration, and showed good agreement with experimental and literature data.

Summary: The study investigates the production of biohydrogen under acidic pH conditions using an intermittent dark-photo circular baffled reactor (IDP-CBR), which successfully achieved efficient hydrogen production from gelatin-based substrate. Adapted bacteria for this process were identified, and the IDP-CBR was found to outperform sequential configurations in maintaining medium pH and promoting light-dependent biohydrogen production.

Summary: This study discusses the management of post-fermentation broth in biohydrogen generation using lignocellulose and starch-based raw materials and proposes a sequential process to improve the efficiency of hydrogen generation and by-products management. By converting simple sugars remaining in the broth into organic acids and using them as substrates for photo fermentation, along with promoting the synthesis of Deep Eutectic Solvents (DES) precursors, the study achieved successful results in hydrogen production and efficient post-fermentation broth management.

Summary: The development of biofuels and the quest for renewable energy sources are crucial issues due to the increasing scarcity of other resources. Hydrogen, known for its high energy capacity and clean attributes, has gained significant attention as a biofuel. Dark fermentation, a method that produces hydrogen from low-value organic waste and has minimal energy requirements, has emerged as an interesting approach in this regard. This article explores the potential of incorporating iron oxide particles into porous scaffolds, with the aim of enhancing hydrogen production through hosting mixed cultures of clostridia. The presence of various metal oxides can promote bacterial growth and stimulate the bioactivity of hydrogen-producing species, thus increasing bio-hydrogen production. The scaffolds analyzed in this study consist of polydimethylsiloxane (PDMS) containing Fe2O3 particles, and were fabricated using the sugar template method. X-ray diffraction patterns were employed to analyze the behavior and stability of these scaffolds in a dark fermentation environment.
