Summary: This study found that lactate fermentation was the main route for H-2 production in mesophilic dark fermentation reactors treating olive mill wastewater. Conversion of lactate to butyrate via pyruvate generation was the key step for H-2 production. Complex interactions among lactate-, acetate-, and H-2-producing bacteria were identified as determining factors in the H-2 production routes.

Summary: The dark fermentation process for biohydrogen production from food waste through fungal solid-state fermentation (SSF) was evaluated. The results showed that Aspergillus tubingensis was the best hydrolysis culture, and the hydrogen yield of food waste hydrolysate (FWH) at different substrate-inoculum ratios was lower than that of untreated food waste (RFW). The microbial community analysis revealed the presence of lactic-acid bacteria genera such as Latilactobacillus and Leuconostoc. The presence of actively growing bacteria during SSF could explain the lower hydrogen yield in the FWH treatment.

Summary: This study examined the working mechanisms of acetic acid inhibition on dark fermentative hydrogen production. The results showed that undissociated acetic acid concentration was the critical factor in acetic acid inhibition. Acetic acid inhibited hydrogen production by altering the dominant microbial community and regulating the metabolic pathways. Controlling the undissociated acetic acid concentration would be an effective strategy to alleviate acetic acid inhibition.

Summary: This study assessed the effect of hydraulic retention time (HRT) on continuous darkfermentative H2 production, and found that the optimal pH depends on the HRT. The highest sugar utilization was observed with cellobiose, followed by xylose and arabinose. The pH conditions had a significant influence on bacterial composition, with low diversity in bacterial culture dominated by the Clostridium genus resulting in stable and high H2 production performance.
