“…However, inhibitory compounds such as furfural and 5‐hydroxymethylfurfural are produced during the acid hydrolysis procedure (Valdez‐Guzmán et al, 2019). In this sense, previous studies carried out in our laboratory for the semi‐continuous H 2 production using suspended biomass (anaerobic sequencing batch reactor) and biofilm (AnSBBR) reactors fed with dilute acid hydrolysates of ATAB, resulted in low to null H 2 production (Rios‐Del Toro et al, 2021). This failure could be attributed to the effect of different exclusion mechanisms as high concentration of inhibitory compounds contained in acid hydrolysates of ATAB, production of antibacterial compounds such as bacteriocins, high abundance of invading non‐HPB species and competition for substrates, including depletion of the essential trace elements (Cabrol et al, 2017; Siedler et al, 2020; Sikora et al, 2013).…”

Aims:The purpose of this study was to characterize the prokaryotic community and putative microbial interactions between H 2 -producing bacteria (HPB) and non-HPB using two anaerobic sequencing batch biofilm reactors (AnSBBRs) fed with tequila vinasses in co-digestion with acid hydrolysates of Agave tequilana var. azul bagasse (ATAB). Methods and Results: Two AnSBBRs were operated for H 2 production to correlate changes in physicochemical and biological variables by principal component analysis (PCA). Results indicated that H 2 yield was supported by Ethanoligenens harbinense and Clostridium tyrobutyricum through the PFOR pathway. However, only E. harbinense was able to compete for sugars against non-HPB. Competitive exclusion associated with competition for sugars, depletion of essential trace elements, bacteriocin production and resistance to inhibitory compounds could be carried out by non-HPB, increasing their relative abundances during the dark fermentation (DF) process. Conclusions:The global scenario obtained by PCA correlated the decrease in H 2 production with the lactate:acetate molar ratio in the influent. At the beginning of co-digestion, this ratio had the minimum value considered for a net gain of ATP. This fact could cause the reduction of the relative abundance of C. tyrobutyricum. Significance and Impact of the Study: This is the first study that demonstrated the feasibility of H 2 production by Clostridiales from acid hydrolysates of ATAB in codigestion with tequila vinasses.

“…Numerous reports can be found using agave biomasses (mainly from Agave tequilana bagasse) as feedstock for hydrogen production in continuous mode. The hydrogen productivity in these reports varies from 0.1 to 13 L H 2 /L d −1 , but with the difference that in most of the reports a pretreatment was required in which the biomass obtained after the pretreatment needs acid or enzymatic hydrolysis, and in some cases, this hydrolysate required further processing for detoxification [44][45][46][47][48][49][50][51][52][53]. Comparing the maximum productivity obtained (1.5 L H 2 /L d −1 ) with the only report in batch mode (to our knowledge) that used A. tequilana baggase to produce hydrogen, by Tapia-Rodríguez et al [53] (0.85 L H 2 /L d −1 ), the potential of guishe juice as substrate can be appreciated.…”

Different strategies have been assessed for the revalorization of guishe to obtain biomolecules. The juice obtained after the mechanical extraction of guishe is rich in phytochemicals and sugars which can be converted to other products. The objective of the present study was to evaluate the production of hydrogen and butanol at different guishe juice concentrations (and therefore, different sugar concentrations) via fermentation in batch mode using Clostridium acetobutylicum ATCC 824. Fermentation assays were performed in triplicate under anaerobic conditions at 35 °C for 142 h. Guishe juice was supplemented with all components of synthetic medium (salts, vitamins and reducing agents), except glucose, and diluted at different concentrations: 20%, 40%, 60%, 80% and 100%. For comparison purposes, a control was carried out in a synthetic medium using glucose as carbon source. Results showed a maximum butanol concentration of 5.39 g/L using 80% guishe juice, corresponding to a productivity and yield of 0.04 g/L h−1 and 0.24 g/g, respectively. Meanwhile, the highest productivity (1.16 L H2/L d−1; 1.99 mmol H2/L h−1) and yield (18.4 L/kg) of hydrogen were obtained with 40% guishe juice. This study demonstrates the potential of guishe juice to be used as a low-cost substrate for hydrogen and butanol production.
