“…Before subjecting the wastewater to fermentative biohydrogen production methods it is required to pretreat it to facilitate effective biohydrogen production. Various pretreatment processes are utilized such as chemical methods like acid hydrolysis, [ 27 ] physical methods like thermal and microwave treatment, [ 28 ] biological methods like enzymatic treatment and mechanical pretreatment like ultrasonication [ 29 ] ( Figure 1 ). Combining two or more pretreatment methods is also used to achieve higher hydrogen efficiency.…”

Currently, there is greater emphasis on using renewable energy sources as compared to conventional sources of energy. Biohydrogen, a renewable energy source, serves as a promising alternative to fossil fuel‐based energy sources. The demand for sustainability is met by producing biohydrogen with the use of wastewater as a substrate. This review article focuses on different ways of biohydrogen production from wastewater with the help of microorganisms, such as light independent processes like dark fermentation and light dependent processes like photo‐fermentation, bio‐photolysis (direct and indirect) and integrated processes like sequential fermentation and combined fermentation. The biochemical pathways, microorganisms employed, specific pretreatment techniques, and efficiency of the biohydrogen production methods by H2 yield and H2 production rate from different wastewater sources are also discussed. Different methods like dark fermentation, photo‐fermentation and integration of these types using various substrates have been put forth. This review article also explains the various pretreatment methods of wastewater like physical, chemical, biological, and mechanical which is essential when using wastewater as substrate in order to increase biohydrogen production. The important characteristics that can influence hydrogen production, such as pH, temperature, hydraulic retention rate, and organic loading rate are also mentioned. In addition, the advantage and drawbacks of biohydrogen production, as well as the potential advancements presently being investigated to tackle these challenges are also highlighted. Therefore, many techniques and technologies are currently adopted to enhance the production of biohydrogen, which will lead to a sustainable environment.

“…The most frequently tested dark fermentation feeds are hydrolysates based on glucose and sucrose. A review of the literature [ 26 , 99 , 100 , 101 , 102 , 103 , 104 , 105 , 106 , 107 , 108 , 109 , 110 , 111 , 112 , 113 , 114 , 115 , 116 , 117 ] showed that for most model studies, substrate concentrations of about 10 g/L were neutral towards the slightly acidic pH of the fermentation broths. Only a few studies [ 104 ] were carried out for a pH > 7; however, as it appears from the content of the study, this is only the starting pH, which drops during fermentation due to the formation of organic acids during fermentation in a continuous UASB reactor.…”

Using bioconversion and simultaneous value-added product generation requires purification of the gaseous and the liquid streams before, during, and after the bioconversion process. The effect of diversified process parameters on the efficiency of biohydrogen generation via biological processes is a broad object of research. Biomass-based raw materials are often applied in investigations regarding biohydrogen generation using dark fermentation and photo fermentation microorganisms. The literature lacks information regarding model mixtures of lignocellulose and starch-based biomass, while the research is carried out based on a single type of raw material. The utilization of lignocellulosic and starch biomasses as the substrates for bioconversion processes requires the decomposition of lignocellulosic polymers into hexoses and pentoses. Among the components of lignocelluloses, mainly lignin is responsible for biomass recalcitrance. The natural carbohydrate-lignin shields must be disrupted to enable lignin removal before biomass hydrolysis and fermentation. The matrix of chemical compounds resulting from this kind of pretreatment may significantly affect the efficiency of biotransformation processes. Therefore, the actual state of knowledge on the factors affecting the culture of dark fermentation and photo fermentation microorganisms and their adaptation to fermentation of hydrolysates obtained from biomass requires to be monitored and a state of the art regarding this topic shall become a contribution to the field of bioconversion processes and the management of liquid streams after fermentation. The future research direction should be recognized as striving to simplification of the procedure, applying the assumptions of the circular economy and the responsible generation of liquid and gas streams that can be used and purified without large energy expenditure. The optimization of pre-treatment steps is crucial for the latter stages of the procedure.

“…Biological hydrogen (H2) production by fermentation is a key technology for H2 production due to its advantages of relatively high H2 production capacity, abundant raw material resources, low carbon footprint, and environmental friendliness (Yin and Wang 2017;Łukajtis et al 2018;Zhang et al 2021a). Hydrogen-producing microorganisms in the fermentation system are the main actors in obtaining hydrogen, the target product.…”

Batch experiments were conducted to investigate the effects of Fe2+ and Na+ on the hydrogen (H2) production performance from three different metabolic type hydrogen-producing bacterial strains. The appropriate amount of Fe2+ significantly promoted the H2 production of all three hydrogen-producing bacteria. The combination of H2 production and liquid products showed that Fe2+ was more suitable for the H2 production and metabolism of E. harbinense ZGX4. When the Fe2+ concentration was 0.05 g/L, the H2 production and liquid products concentrations were 2170 mL/L-medium and 6530 mg/L, respectively. Na+ enhanced the H2 production of E. harbinense ZGX4 and C. butyricum 1.209 but inhibited the H2 production of E. cloacae 1.2022. Na+ made C. butyricum 1.209 exhibit the best H2 production and metabolic performance when the Na+ concentration was 2 g/L, while the H2 production, and liquid products concentration were 2460 mL/L-medium and 5350 mg/L, respectively. At the end of the experiment, it was found that the addition of Fe2+ could change the type of fermentation in C. butyricum 1.209. Therefore, further exploration of the effects of other metal ions on model hydrogen-producing strains has great potential for achieving high hydrogen production rates, among other things.
