Insights into Biohydrogen Production Through Dark Fermentation of Food Waste: Substrate Properties, Inocula, and Pretreatment Strategies

Energies, Год журнала: 2024, Номер 17(24), С. 6350 - 6350

The growing population and economic expansion have led to increased energy demand while presenting complex waste generation management challenges, particularly in light of climate change. Green hydrogen, which is considered a major clean carrier, can also be generated from food through process known as dark fermentation. production fermentative hydrogen biomass residues, general, influenced by the type feedstock, source inoculum, their pretreatment handling strategies. Food suitable substrate for fermentation has variable composition, factor limiting yield. This review critically assesses sources, focusing on physical chemical methods, strategies optimizing production. paper highlights discusses various inoculum sources innovations regarding enrichment applications inocula Based literature analysis, advanced research required develop more sustainable specific that consider properties inoculum. approach will aid preventing inhibition inefficiency during process.

The environmental concerns regarding fossil plastics call for alternative biopolymers such as polyhydroxyalkanoates (PHAs) whose manufacturing costs are however still too elevated. Autotrophic microbes like Cupriavidus necator, able to convert CO2 and H2 into PHAs, offer an additional strategy. Typically, the preferred source expensive pure gases or syngas, which has toxic compounds most PHAs-accumulating strains. In this work, first time, originating from acidogenic reactor were converted autotrophically poly(3-hydroxybutyrate) P(3HB). During stage, a mixed microbial community continuously catabolized melon waste (26.7 %) (49.2 that then used in second bioreactor by C. necator DSM 545 accumulate 1.7 g/L Additionally, VFAs (13 gCOD/L) produced during acidogenesis processed 2.7 of P(3HB-co-3HV). This is proof-of-concept using acidogenic-derived fruit produce PHAs.
