“…This integrated process is more economical for hydrogen production from lignocellulose [15]. As a proficient hydrogen producer, the genus Clostridium has been widely researched in dark fermentative hydrogen production because of its high hydrogen productivity, wide range of substrate utilization and high resistance to adverse conditions [16][17][18]. Moreover, the Clostridium species is usually the dominant hydrogenproducing genus which exists in anaerobic mixed cultures [19].…”

Screening new Clostridium strains that can efficiently utilize lignocellulose to produce hydrogen is extremely important for dark fermentative hydrogen production. In this study, a mesophilic hydrogen-producing bacterium, identified as Clostridium populeti FZ10, was newly isolated from compost acclimated by microcrystalline cellulose. The strain could produce hydrogen from various cellulosic substrates. The performances of hydrogen production from microcrystalline cellulose (MCC) and corn stalk (CS) were especially investigated. The maximum hydrogen yield and hydrogen production rate from MCC were 177.5 ± 4.8 mL/g and 7.7 ± 0.2 mL·g−1·h−1, respectively. Furthermore, scanning electron microscopy (SEM) images showed that the structure of CS was destroyed after fermentation, which could be attributed to the presence of exoglucanase, endoglucanase, β-glucosidase and xylanase produced by Clostridium populeti FZ10. The maximum hydrogen yield and hydrogen production rate from CS were 92.5 ± 3.7 mL/g and 5.9 ± 0.2 mL·g−1·h−1,respectively, with a cellulose degradation of 47.2 ± 2.3% and a hemicellulose degradation of 58.1 ± 2.0%. This study demonstrates that Clostridium populeti FZ10 is an ideal candidate for directly converting lignocellulose into biohydrogen under mesophilic conditions. The discovery of strain C. populeti FZ10 has special significance in the field of bioenergy.

“…In studies where specific bacteria were preferred for hydrogen production, Clostridium species were generally used. The raw materials and bacteria used included glucose monohydrate and Clostridium butyricum CWBI1009 [ 57 ], food waste and Clostridium butyricum [ 58 ], non-sterile food waste and Clostridium butyricum TISTR 1032 [ 59 ], vine shoots and Clostridium butyricum [ 60 ], glucose and molasses and Clostridium butyricum TM-9A [ 61 ], and tequila vinasses and Ethanoligenens harbinense and Clostridium tyrobutyricum [ 62 ]. The majority of hydrogen-producing bacteria can grow in wide pH ranges.…”

“…The most crucial variables in the anaerobic fermentation process are temperature and pH. These variables affect the synthesis of biohydrogen and microorganisms that produce H 2 [ 55 ]. In the current study, the amount of biohydrogen reduced at low pH may be due to the inhibition of hydrogenase activity, which is a key enzyme in the biohydrogen production process or inhibition of the metabolic activity of bacteria [ 55 – 58 ].…”

Background Hydrogen is a promising source of alternative energy. Fermentative production is more feasible because of its high hydrogen generation rate, simple operating conditions, and utilization of various organic wastes as substrates. The most significant constraint for biohydrogen production is supplying it at a low cost with fewer impurities. Results Leaf biomass of Calotropis procera was used as a feedstock for a dark fermentative production of hydrogen by Bacillus coagulans AH1 (MN923076). The optimum operation conditions for biohydrogen production were 5.0% substrate concentrationand pH 9.0, at 35 °C. In which the biohydrogen yield was 3.231 mmol H2/g dry biomass without any pretreatments of the biomass. A freshwater microalga Oscillatroia sp was used for upgrading of the produced biohydrogen. It sequestrated 97 and 99% % of CO2 from the gas mixture when it was cultivated in BG11 and BG11-N media, respectively After upgrading process, the residual microalgal cells exhibited 0.21mg/mL of biomass yield,high content of chlorophyll-a (4.8 µg/mL) and carotenoid (11.1 µg/mL). In addition to Oscillatroia sp residual biomass showed a lipid yield (7.5–8.7%) on the tested media. Conclusion Bacillus coagulans AH1 is a promising tool for biohydrogen production avoiding the drawbacks of biomass pretreatment. Oscillatroia sp is encouraged as a potent tool for upgrading and purification of biohydrogen. These findings led to the development of a multiproduct biorefinery with zero waste that is more economically sustainable. Graphical Abstract
