“…Among them, Propionibacteriaceae can ferment carbohydrates and produce propionic acid, acetic acid or a mixture compound of organic acids including butyric acid, formic acid, and lactic acid. Sporolactobacillaceae is involved in metabolic pathways of acetic acid and lactic acid ( Park et al, 2019 ). Short-chain fatty acids act as energy source of intestinal epithelial cells ( Donohoe et al, 2011 ), which can promote the development of intestinal villi, regulate intestinal morphology, and structure of broilers ( Shakouri et al, 2009 ).…”

Biohydrogen is a source of renewable and clean energy. Many countries are working to generate biohydrogen energy as a means of combating the present global warming trend. This review paper aims to highlight the available information on hydrogen production from municipal solid waste biomass and also highlight several factors influencing the rate of biohydrogen production and their challenges in the future. The study of hydrogen production processes was aimed at a complete understanding of modern hydrogen production technologies, both implemented in practice and under research or development. The review revealed some advantages of biological methods for producing hydrogen gas compared to chemical ones. Also, this paper identified different factors that affect the biohydrogen production process such as type of bioreactors, temperature, pH, light, nutrients. This study also brings to the surface the challenges that need attention from researchers.

“…Different reactors have been reported in the literature, including anaerobic packed-bed reactor (AnPBR), anaerobic structured-bed reactor (AnSTBR), anaerobic fluidized-bed reactor (AnFBR), expanded granular sludge bed reactor (EGSB), up-flow anaerobic sludge blanket reactor (UASB), anaerobic sequencing batch reactor (AnSBR), continuously stirred tank reactor (CSTR) [10], and, more recently, dynamic membrane reactors (DMBR) [11,12]. Among them, the CSTR is perhaps the most widely used reactor configuration to produce biohydrogen via DF due to easy operation and control, as well as owing to its flexibility to operate under suspended and attached biomass configurations; however, DMBRs have sustained very high hydrogen productivities using model substrates [11,13,14], and even more complex ones such as algal biomass [12]. Last but not least, the type of inoculum used, as well as its pretreatment method, are also major factors influencing the DF process.…”

Dark Fermentation Process Response to the Use of Undiluted Tequila Vinasse without Nutrient Supplementation

et al. 2021

The technical feasibility of valorizing tequila vinasse (TV), a wastewater with high pollution potential, through the production of biogenic hydrogen via dark fermentation, has long been proven in diverse lab-scale reactors that were operated either in batch or continuous mode. However, such systems have mainly been tested with diluted streams and nutrient supplementation, hindering the techno-economic attractiveness of the TV-to-hydrogen concept at large scale. In this study, the feasibility of producing hydrogen from high-strength undiluted TV with no added extra nutrients was evaluated under batch mesophilic conditions. Additionally, the use of two different acidogenic inocula obtained either by heat or heat-aeration pretreatment was investigated to get a greater understanding of the effect of inoculum type on the process. The results obtained showed that the TV utilized herein contained macro- and micro-nutrients high enough to support the hydrogenogenic activity of both cultures, entailing average hydrogen yields of 2.4–2.6 NL H2/L vinasse and maximum hydrogen production rates of 1.4–1.9 NL H2/L-d. Interestingly, the consumption of lactate and acetate with the concomitant production of butyrate was observed as the main hydrogen-producing route regardless of the inoculum, pointing out the relevance of the lactate-driven dark fermentative process. Clostridium beijerinckii was ascertained as key bacteria, but only in association with microorganisms belonging to the genera Enterobacter and Klebsiella, as revealed by phylogenetic analyses.
