“…Using a pH-control strategy to enhance biohydrogen production from SH hydrolysate It has been reported that low pH inhibits H 2 production because it affects hydrogenase activity and many aspects of microbial metabolism, including utilization of substrate, biogas content, and types of organic acids [15,18,33]. Low pH of fermentation media usually results in lower intracellular ATP levels and causes inhibition of bacterial growth and change in their metabolic pathways (acidogenesis to solventogenesis) resulting in low H 2 production [21,33].…”

The potential of isolated actinomycetes and fungi were evaluated for the cellulase and xylanase production under solid state fermentation conditions. Maximal secretion of enzymes was observed with Phanerochaete chrysosporium using soybean straw. The potential of the produced crude enzyme complex was demonstrated by two-step enzymatic hydrolysis of untreated and mild acidpretreated sorghum husk (SH). A cellulase dose of 10 filter paper units (FPU) released 563.21 mg of reducing sugar (RS) per gram of SH with 84.45% hydrolysis and 53.64% glucose yields, respectively. Finally, enzymatic hydrolysates of SH were utilized for hydrogen production by Clostridium beijerinckii. Effects of temperature, pH of media, and substrate concentration on the biohydrogen production from SH hydrolysates were investigated. The optimal conditions for maximal hydrogen production using SH hydrolysate were determined to be a loading of 5.0 g RS/L, at 35°C, and controlled pH at 5.5. Under these optimal conditions, the cumulative H 2 production, H 2 production rate, and H 2 yield were 1,117 mL/L, 46.54 mL/L/h, and 1.051 mol/mol RS, respectively. These results demonstrated a cost-effective hydrogen production is possible with sorghum husk as a lignocellulosic feedstock.

“…Biohydrogen production is a complex process and is greatly influenced by many factors, including microorganism seeding, pH, temperature, organic loading rate, metal ions, and oxidation-reduction potential. Optimization of these factors and controlling suitable environmental conditions could enhance dark fermentative H 2 production [21,22].…”

“…Since the physicochemical H 2 production processes are energy-intensive and hazardous to the environment, there have been urgent needs for biological H 2 production from renewable materials. Though thermo-chemical methods of producing H 2 are an easier approach, biological methods are safer and economically viable (Kim et al, 2008).…”

“…Most of the studies on H 2 production are carbohydrate-based (Bai et al, 2004;Ding et al, 2008;Lin and Lay, 2004;Roychaudhury et al, 1988;Zhang et al, 2003) since these materials can be improved by inhibition of the activity of H 2 -quenching pathways or by reduction of H 2 and CO 2 partial pressure (Nath and Das, 2004;Ewan and Allen, 2005;Kim et al, 2008;Nandi and Sengupta, 1998;Hallenbeck and Benemann, 2002;Bai et al, 2004;Ding et al, 2008;Lin and Lay, 2004;Roychaudhury et al, 1988;Zhang et al, 2003;Das and Veziroglu, 2001;Lamed et al, 1988;Oh et al, 2003;Park et al, 2005;Kim et al, 2004).…”

Bio-hydrogen (H 2 ) production in a thermophilic anaerobic bioreactor with carbon dioxide (CO 2 ) utilization at the headspace was investigated at different ratio of Biomass substrate to Microorganism (B/M). A 3 mL volume of 80% NaOH (m/v) solution was continuously hung at the headspace of the bioreactors to capture carbon dioxide. The utilization of CO 2 at its headspace, proved to enhance bio H 2 production. The highest Cumulative Biohydrogen Yield (CHY) of 131.81±3.47 mL-H 2 /gVS was measured at the ratio of 8.10 parts of biomass to 0.90 parts of Acclimatized Seed Sludge (ASS), B/M 9, while 4.17 parts of similar biomass to 0.83 parts of ASS (B/M 5) had a biohydrogen production of 90.70±16.67 mL-H 2 /gVS. The B/M of 6.12 parts of biomass to 0.88 parts of ASS (B/M 7) produced a CHY of 84.72±18.35 mL-H 2 /gVS while the control bioreactors without CO 2 utilization (without and with biomass substrate) yielded a 0.06±0.035 mL-H 2 /gVS and a 3.27±0.78 mL-H 2 /gVS respectively. The mechanism of the biofermentation in this anaerobic reaction produced two possible resulting reaction; the acetogenesis of CO 2 with H 2 and the hydrogenotrophic methanogenesis. These reactions consumes hydrogen in the process to produce methane or acids. The presence of 80% (m/v) NaOH solution at the headspace inside the bioreactors, utilizes the CO 2 producing a hydrogen-rich region in space: The highest average H 2 yield of 51.83 mL-H 2 after 49.1 h with B/M 9 without methane was due to carbon dioxide utilization in the bioreactors. A univariate ANOVA and Pair-wise Tukey HSD statistical analysis revealed that the CHY of B/M9 was significantly higher than the other B/Ms. The highest yield, 55.85 mL-H 2 /gVS obtained with the bioreactor of B/M 9 was optimum for H 2 production. The results concluded that H 2 production is also enhanced by CO 2 utilization at the headspace.

“…KIM et al (2008) et al, 2014), conforme descrito na Equação 8 (item 3.4.2). A formação do ácido butírico como principal subproduto da produção de H2 pela cepa isolada é, provavelmente, responsável pelo rendimento de H2 relativamente baixo, quando comparada com outros trabalhos da literatura, conforme discutido anteriormente.…”
