Summary: This study found that using a combination of two or more conductive materials (CMs) can improve the production in a two-stage fermentation process (TSFP). Magnetite nanoparticle (MNP) played a crucial role in enhancing H2 production in the first stage, while powdered activated carbon (PAC) contributed to higher CH4 production in the second stage.

Summary: This study found that supplementation of N-2 and Air-nanobubble water can significantly enhance the efficiency of hydrogen and methane production in the two-stage anaerobic digestion of food waste. Air-NBW has a promoting effect on both hydrogen and methane production stages, while N-2-NBW only has a positive impact on the hydrogen production stage.

Summary: This study proposed a lactate-based two-stage anaerobic digestion process and investigated the effect of inoculum addition and culture pH on hydrolysis-acidogenesis and further methanization. The results showed that self fermentation at uncontrolled pH can lead to lactate accumulation and increased bioenergy production rate.

Summary: The use of multi-stage anaerobic digestion technology is effective in treating agroindustrial effluents, especially substrates like manipueira, vinasse, and dairy wastewater which yield high amounts of hydrogen and methane. Future research should focus on new microbial technologies and optimizing process parameters for maturation and scale-up of the two-stage anaerobic digestion technique.

Summary: Dark fermentation is a simple method for hydrogen production using various organic wastes as feedstock. This study optimized the methane yield by reducing the hydraulic retention time in a two-stage reactor system. Functional inference and microbial community analysis were conducted to understand the changes in each reactor stage. The results showed an overall increase in biogas production and improvement in gas quality.

Summary: Batch experiments were conducted to evaluate the production of biohydrogen and biomethane through co-digestion of chicken manure and food waste. Results showed that both hydrogen and methane yields were improved in the co-digestion process, but there might be some inhibition factors in the chicken manure affecting the hydrogen fermentation.

Summary: The study investigated the effects of high salinity on the co-production of hydrogen and methane from two-stage AD of food waste, with the addition of Air-NBW found to increase hydrogen and methane yields. The results suggest that improvement in microbial electron transfer and enzymatic activities in each stage through Air-NBW addition could provide an efficient approach for hydrogen and methane recovery under high salinity conditions.

Summary: The utilization of food waste is important, and this study focused on converting food waste to single-cell protein (SCP) using Yarrowia lipolytica. A two-stage fermentation process significantly increased the protein content of the biomass, and transcriptomic analysis revealed up-regulation of SCP-producing genes.

Summary: The study found that initial pH plays a significant role in the two-stage hydrogen and methane production process by co-digestion of food waste and waste activated sludge. While hydrogen production remained consistent across a range of initial pH levels, methane production was influenced by the pH conditions. Acidic conditions were beneficial for hydrogen fermentation efficiency but had a negative impact on methane fermentation, while alkaline conditions showed the opposite pattern.

Summary: For the two-stage anaerobic digestion of food waste, the food-to-microorganism (F/M) ratio affects hydrogen production, which can be improved by increasing F/M ratio. The addition of Tween 80 can shorten the time required for methane production. Economic analysis of energy recovery calculation suggests that A-10 + M-10 T condition is more reasonable for TSAD.

Summary: This study investigated the feasibility of hydrogen and L-lactic acid production from starch using Thermotoga neapolitana under capnophilic lactic fermentation conditions. Different yields of H2 and lactic acid were achieved from potato and wheat starch, with higher lactic acid production observed in the presence of CO2. A kinetic model was applied to simulate the metabolic profile and bioreactor performance, suggesting a new direction towards transforming agricultural food waste into biofuels and valuable biochemicals.
