This process can be carried out without the need for light, making it easier and more efficient to operate in different environments and at a lower cost. It also utilizes a wide range of substrates, making it highly adaptable to waste-to-energy applications. Clostridium spp. are particularly favored in this method due to their versatile metabolism, ability to utilize a wide range of substrates, and high H2 yields. Anaerobes and facultative anaerobes are mostly used in studies due to their efficient hydrogenase enzyme activity and metabolic pathways. A pH range of 5.5–6.5 and a temperature of 30–37 °C for mesophiles and 55–60 °C for thermophiles are usually preferred in addition to the other parameters such as hydraulic retention time and substrate used. The highest H2 yield of 9.39 mol H2/mol sucrose consumed was obtained by C. beijerinckii using sucrose as a substrate under batch mode conditions at 37 °C and pH 6–7. The review analyzes different bacterial species and examines the influence of optimized parameters required on H2 yield in different bioreactor operating modes. info:eu-repo/grantAgreement/ES/NextGenerationEU/PR-H2CVAL4-C1- 2022-0049 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 2.5 2024 ENGINEERING, MULTIDISCIPLINARY 50 / 179 = 0.279 2024 Q2 T1 CHEMISTRY, MULTIDISCIPLINARY 123 / 239 = 0.515 2024 Q3 T2 MATERIALS SCIENCE, MULTIDISCIPLINARY 284 / 461 = 0.616 2024 Q3 T2 PHYSICS, APPLIED 101 / 187 = 0.54 2024 Q3 T2 0.521 2024 Computer Science Applications 2024 Q2 Engineering (miscellaneous) 2024 Q2 Process Chemistry and Technology 2024 Q2 Instrumentation 2024 Q2 Materials Science (miscellaneous) 2024 Q2 Fluid Flow and Transfer Processes 2024 Q2 5.5 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Fernandes, Annabel Lopes, Ana Grasa, Laura Universidad de Zaragoza (orcid)0000-0002-5306-9365 Salafranca, Jesús Universidad de Zaragoza (orcid)0000-0002-6607-1309 2009 750 Universidad de Zaragoza Dpto.
