“…Therefore, we highlight B. amyloliquefaciens among the isolates as in addition to showing the highest yields in H 2 production, reaching 17% of the theoretical yield. This microorganism is described in the literature for its activities in various biotechnological processes; however, it is little known as a producer of hydrogen, being recently reported by Ref [31]. using glucose as substrate.…”

“…The optimum glucose concentration of 10 g/l observed in this study is in agreement with mesophilic Bacillus sp. FS2011 and Clostridium beijerinckii Fanp3 strains (Pan et al 2008;Song et al 2013) but differs with other work on hydrogen producing Klebsiella strains (Niu et al 2010;Chookaew et al 2012). Strain ABZ11 also shows high carbohydrate uptake, with 74% of glucose consumed after 2 h of fermentation due to high substrate conversion efficiency attributed to the incubation temperature and oxygen, before complete utilization around 48 h.…”

Lower temperature biohydrogen production has always been attractive, due to the lower energy requirements. However, the slow metabolic rate of psychrotolerant biohydrogen-producing bacteria is a common problem that affects their biohydrogen yield. This study reports on the improved substrate synthesis and biohydrogen productivity by the psychrotolerant Klebsiella sp. strain ABZ11, isolated from Antarctic seawater sample. The isolate was screened for biohydrogen production at 30°C, under facultative anaerobic condition. The isolate is able to ferment glucose, fructose and sucrose with biohydrogen production rate and yield of 0.8 mol/l/h and 3.8 mol/g, respectively at 10 g/l glucose concentration. It also showed 74% carbohydrate uptake and 95% oxygen uptake ability, and a wide growth temperature range with optimum at 37°C. Klebsiella sp. ABZ11 has a short biohydrogen production lag phase, fast substrate uptake and is able to tolerate the presence of oxygen in the culture medium. Thus, the isolate has a potential to be used for lower temperature biohydrogen production process.

“…The latter two were the N 2 fixing strain and the nitrifying bacteria, respectively . The Bacillus cereus was one kind of butyric acid fermentation type strain, which produced hydrogen through the pyruvate metabolism pathway resulting in a large amount of butyric acid in the metabolites . During the stable biohydrogen production periods (OLR: 60 g glucose /L · d, pH in : 8.0), the proportion of Bacillus cereus in the mixed culture varied very slightly from 25 to 30 %.…”

Biohydrogen generation using anaerobic sludge from a sewage treatment plant is a promising strategy for converting waste into renewable energy. The porous foam SiC ceramic structured packing was used as a support in the up‐flow anaerobic sludge blanket (UASB) reactor to enhance the biohydrogen yield. Using glucose as the major carbon source, the SiC‐UASB reactor was continuously operated under the organic loading rates (OLR) between 30 and 90 gglucose/L · d at a hydraulic retention time (HRT) of 4 h. The maximum hydrogen production rate (5.24 L/L · d) and hydrogen content (50 %) were obtained at 60 gglucose/L · d OLR. It demonstrated that the reaction of fermentation was predominated by the butyric acid pathway. The employment of SiC packings resulted in quick startup (∼5 days) and high efficiency of hydrogen production. The buffering capacity and the cell culture immobilization ability of the UASB reactor were obviously improved by the application of SiC packings, which increased the feasibility of scale‐up of the continuous biohydrogen production system.
