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

Lactic acid fermentation has recently been shown to be a robust storage strategy for food waste prior conversion biohydrogen through dark fermentation. However, the importance of initial microbial communities and, more particularly, exogenous microorganisms on lactic acid-rich stored substrate is not yet fully elucidated. This study investigates impact introducing inoculum production in Results showed inoculation produced statistically significant increase rate (Rm) by 199%, 250%, 137%, 130%, 19%, and 10% compared non-inoculated after at 4 °C, 10 23 35 45 55 respectively. Interestingly, no maximum yield (Pm) was observed, but increased accumulation acetate, up 160% endogenous inoculum. The main hydrogen-producing bacteria (HPB) were affiliated with Clostridium sp., while Prevotella_9 another known HPB, found °C. In this study, interest convert demonstrated an along higher co-products, e.g., acetate. Such findings are promising further development process coupling, combining complex waste.
