The aim of this review is to provide a comprehensive analysis the membrane-assisted dark fermentation process for bioH2 production and purification. This initially analyses need current state art in H2 through fermentation, evaluating research landscape maturity level technology. Key factors influencing are then examined, along with emerging trends fermentative systems. subsequently addresses challenges inherent explores potential opportunities enhance efficiency. Special attention given membrane technology as promising strategy intensification recovery. Finally, provides an in-depth discussion inorganic membranes, mixed matrix membranes (MMMs), thin ultrathin each type terms its advantages, limitations, purification performance. offers valuable insights into intensifying by leveraging

This study investigated three different fermentation approaches to explore the potential for producing biohydrogen, carboxylic acids, and methane from hydrolysates of thermally dilute acid pretreated brewer's spent grains (BSG). Initially, research focused on maximizing volumetric hydrogen production rate (HPR) in continuous dark (DF) BSG by varying hydraulic retention time (HRT). The highest HPR reported date 5.9 NL/L-d was achieved at 6 h HRT, with a Clostridium-dominated microbial community. effect operational pH (4, 5, 6, 7) acidogenic then investigated. A peak concentration 17.3 g CODequiv./L recorded an associated productivity 900.5 ± 13.1 mg CODequiv./L-h degree acidification 68.3 %. Lactic bacteria such as Limosilactobacillus Lactobacillus were dominant 4–5, while Weissella, Enterococcus, Lachnoclostridium appeared 7. Finally, this evaluated biochemical DF broth unfermented found high yields 659 517 NmL CH4/g-VSadded, respectively, both within one week. Overall, results showed that can be low-cost feedstock bioenergy valuable bio-based chemicals circular economy.

Lactic acid bacteria are widely used because they produce lactic naturally, resistant to acidic pH and a wide temperature range, frequently as primary metabolite. In this study, Enterococcus durans isolated from buffalo milk was employed in fermentation with the goal of obtaining parameters for an effective process enabling use lactose alternative carbon source. Fermentative such initial concentration source, dissolved oxygen concentration, cell recycling, batch pulse operation mode were studied find best conditions L-(+)-lactic production. The association 20 g·L−1 10 glucose enabled bioconversion acid. Anaerobiosis did not contribute increasing Batch recycling strategy that enhanced production consumption, reaching 26.07 g·L−1, 0.36 g·L−1·h−1 productivity yielding about 0.86 g·g−1. It is fundamental evaluate provide efficient sustainable methods.

This study explores three valorization strategies for brewer's spent grain (BSG) to harness its potential within a circular economy framework. It examines the fermentative hydrogen production and acidogenic fermentation from thermal diluted-acid BSG hydrolysates, as well biogas non-fermented hydrolysates collected post-dark (DF). Continuous DF was evaluated at different hydraulic retention times (HRTs). The highest rate of 5.9 NL/L-d so far reported achieved 6-h HRT, while yield 32.8 NL H2/kg dry attained 12-h HRT. acidogenesis performed operational pHs 4–7. Organic acids (mainly lactate acetate) concentration peaked 17.3 g-CODequiv./L pH 6. Finally, unfermented fermented showed high methane yields 517 659 NmL CH4/g-VSadded, respectively. highlights brewing industry's biofuel organic acid BSG.
