“…Resulted data demnostrated a significant decrease in cumulative hydrogen production when the fermentation pH was below 7.0. Decreasing of produced hydrogen yield from pH 7.0 to 3.0 could be attributed to the effect of the lower pH values on biomass growth and the activity of hydrogenase enzymes which are involved in anaerobic hydrogen production pathways of the hydrogen producing bacteria (Hawary et al, 2019;Sivagurunathan & Lin, 2020). Also, these data were in agreement with Stavropoulos et al (2016) who stated that efficient pH ranges for biohydrogen production were from 4.5 to 9.0.…”

H YDROGEN (H 2 ) is expected to become the most sustainable and promising clean alternative fuel in the future. This study evaluated the potential of a new facultative anaerobic bacterium isolated from cow rumen to produce H 2 from sugarcane molasses. The bacterial isolate RM122 produced 451.67 ±12.14 and 387.67 ±19.23mL/L H 2 on 6% glucose and 6% molasses sugar, respectively. RM122 was characterized phenotypically, identified genotypically by 16S rRNA sequence analysis as Escherichia marmotae, and deposited in NCBI GenBank database with the accession number OP345936. H 2 production was improved to 1670.00 ±40.41mL/L by application of optimization experiments design and kinetic study. Sugarcane molasses was used as a fermentation substrate and the optimum sugar concentration was 4%, The recorded maximum hydrogen production (H max ) was 560.00±25.98mL/L with R max (maximum hydrogen production rate) of 31.43 ±2.14mL/L/h, R max (MGM) of 30.73 mL/ L/h and λ (lag phase) of 15.19h for 52.43 fermentation time. H max of 646.67 ±23.33mL/L with R max (Exp) of 35.28 ±2.65mL/L/h, R max (MGM) of 31.90mL/L/h, λ of 13.92h and R 2 of 0.9999 were obtained at the optimum pH 8. At the optimum fermentation temperature (35°C), λ of 4.12h was achieved to maximize hydrogen production to 828.33 ±21.67mL/L with R max (MGM) of 27.98mL/L/h, and R 2 of 0.9594. At the optimum inoculum size (10%, v/v), the recorded H max was 1670.00 ±40.41mL/L with R max (Exp) of 60.00 ±2.04mL/L/h and λ of 13.50h. These findings suggest using E. marmotae RM122 as a prospective biohydrogen producer from cheap agro-industrial wastes.

“…The hydrogen production is reduced at pH < 5 as there is a reduction in biomass growth but a higher hydrogen yield is achieved at pH > 5. [21] For hydrogen formation by batch mode from cheese whey, it was found that hydrogen production was initially high at an initial pH 6, followed by a reduction in hydrogen yield. [77] Stavropoulos et al [78] conducted a study to estimate the impact of different pH values on hydrogen production determining that the topmost hydrogen formation was at a pH 5. pH also affects the metabolic pathways of the microorganisms.…”

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.

Biohydrogen production by fermentative bacteria is one of the most prospective alternative ways for fossil fuels. Therefore, this study aimed to isolate new facultative anaerobic bacteria from cow rumen as highly hydrogen producers from sugarcane molasses. Among the isolated ruminant anaerobic bacteria, the isolate RM92 was the highest hydrogen producer with maximum cumulative hydrogen (Hmax) of 426.67±14.56 mL/L. This bacterial isolate (RM92) was identified phenotypically and genotypically as Escherichia fergusonii. The 16S rRNA gene sequence was deposited in NCBI GenBank database under the accession number OP185369. Optimization expermients design for maximization of hydrogen production by E. fergusonii RM92 increased the Hmax to 1280.00 ±34.64 ml/L with maximum hydrogen production rate (Rmax) of 36.92±0.89 ml/L/h on 4% molasses sugar concentration, pH 8, incubation temperature 40 °C and initial inoculum size 30% (v/v). These findings suggest that E. fergusonii RM92 could be used as a potential hydrogen producer from cheap agro-industrial wastes.
