“…TW80 has also been proven to have the potential to boost hydrogenase and hydrolytic enzyme activities when applied in combination with conductive materials that enhance electron transfer during fermentation [ 70 ]. Moreover, the addition of iron to the methanogenesis system has been observed to increase and maintain stable methane-producing activity [ 71 , 72 ], as iron is an essential part of several key enzymes required for methanogens [ 73 ]. Despite the identified positive synergism, however, there are still gaps in the understanding of the synergistic mechanism between iron and surfactants on AD performance, especially regarding activity related to methanogenesis, which is the key process for biogas generation.…”

“…As acidogenesis can be evaluated using methyl red test, acetogenesis can also be checked and verified using methyl red and gas production tests [12,58]. Hydrogenase enzymes are crucial in the usage and generation of hydrogen gas and gas production test give a hint if hydrogen is being produced or not [59] [60]. Dehydrogenase enzyme Facilitates the transformation of formate into carbon dioxide and hydrogen, providing acetogens with an alternative method to generate substances for methanogenesis, this step can also be verified using gas production test [61].…”

The Baker yeast industry wastewater is a substantial environmental concern because of industrial contamination, representing a large reservoir of untapped resources. Anaerobic digestion (AD), a multi-stage biological process, can promote sustainability by producing methane (CH4) from baker’s yeast effluent. This manuscript presents a novel method for isolating bacterial strains from animal remnants and effluent produced during baker's yeast manufacturing. The method is intended to preferentially discover bacterial strains that not only can survive but also show increased growth and metabolic activity in particular environmental circumstances. The bacterial consortia, which was kept separate, not only reduced the incubation duration by five days but also decreased BOD and COD levels by 45% and 51.3%, respectively. Additionally, it increased the purity of methane to 73%. This technique proposes a hopeful method for treating industrial effluents with high levels of COD and BOD, which is in line with the objective of achieving zero discharge and promoting water recycling. AD as compared to membrane filtration, coagulation, electrocoagulation, ozonation, aerobic digestion is feasible and economical process. Sustainability is ensured by production of methane and wastewater treatment.

Hydrogen is believed to be the most potential energy‐resources in the coming time due to its high energy density and zero greenhouse gas footprint. Among all types of hydrogen production processes, bio‐based hydrogen (biohydrogen) generation processes are found to be relatively cleaner than the other processes. In this review article current biohydrogen generation processes are critically reviewed to understand the critical factors associated with the hydrogen generation along with the challenges to be eliminated. In this review the factor like types of substrates, their pretreatment, bioreactor design, and other parametric influences on the overall biohydrogen production is discussed. Also, impact of different catalyst in hydrogen production has been discussed in this topic. The review indicated that most of the current hydrogen‐research are focused on the development of processes with high yield. However, one of the major drawbacks of biohydrogen process is purification of H2 from the gaseous mixture produced by microbial strains. To establish the biohydrogen production processes as promising as it considered to be there needs to have a robust purification system. Also, this review highlights that more rigorous research on the biohydrogen storage and its hazard analysis is necessary to meet the future expectation of hydrogen use in mass‐scale.
