“…4 mol hydrogen per mol glucose with acetate production and 2 mol hydrogen 50 per mol glucose with butyrate production. Thus the butyrate/acetate ratio can be used as a 51 reliable indicator of the efficiency of fermentative hydrogen production and of the metabolic 52 pathways used during glucose fermentation [7]. Collected liquid samples were centrifuged at 13000 g for 10 min and the supernatants 146 obtained were filtered through a 0.2 µm cellulose acetate membrane (Minisart Sartorius) and 147 analysed by HPLC for glucose, ethanol, lactate, acetate, formate and butyrate.…”

The production rates and yields were investigated at 30 °C in a 2.3 l bioreactor operated in 19 batch and sequenced-batch mode using glucose and starch as substrates. In order to study the 20 precise effect of a stable pH on hydrogen production, and the metabolite pathway involved, 21 cultures were conducted with pH controlled at different levels ranging from 4.7 to 7.3 22 (maximum range of 0.15 pH unit around the pH level). For glucose the maximum yield (1.7 23 mol H 2 mol -1 glucose) was measured when the pH was maintained at 5.

“…One of the predominat bacteria was Clostridium beijerinckii in pretreated variants with the exception of TB which demonstrated a low level of hydrogen production. It is known that C. beijerinckii belongs to hydrogen-producing organisms [26][27][28]. Fungi Trichoderma asperellum inoculated in silage at the beginning of aerobic pretreatment procedure had lost their viability after 46 days of anaerobic fermentation.…”

Bacteria produce hydrogen during anaerobic dark digestion of carbon rich natural resources including renewable cellulosic materials. The purpose of this work was to study the impact of maize silage pretreatment with Trichoderma fungi, bioaugmentation with defined bacterial inocula and/ or biostimulation with humic acids and an additional inorganic nitrogen source on the fermentative hydrogen production in laboratory batch assay. Experiments were carried out with and without Trichoderma asperellum pretreated silage. The selected bacterial inocula consisted of Clostridium, Enterobacter and Tissierella species, with or without Bacillus mycoides. Headspace gas composition, the amount of dry particulate matter, chemical oxygen demand and concentration of volatile fatty acids in liquid were determined. Bacterial communities were studied with fluorescence in situ hibridization. The predominant cultivable microbial species were isolated and identified. The study demonstrated a significant increase of hydrogen production from maize silage by indigenous bacteria after pretreatment with Trichoderma in comparison with silage untreated with Trichoderma. From tested factors, pretreatment, biostimulation with additional nutrients (ammonium nitrate and/ or humic acids) and bioaugmentation with defined bacterial inocula, pretreatment demonstrated significant improvement of hydrogen production from maize silage. Thereby, aerobic treatment with Trichoderma could be recommended for the pretreatment of silage for the purpose of fermentative production of hydrogen.

“…HE1 (Wu. et al 2008); Escherchia coli (Turcot, 2007); e Clostridium (Ferchichi, 2005;Liu et al 2005;Kim et al 2006;Lin et al 2007;Ding, 2009). Tendo em vista a baixa velocidade de crescimento das arquéias metanogênicas frente às bactérias fermentativas, e a baixa velocidade de consumo de ácidos orgânicos, esse balanço torna-se limitante do processo de digestão anaeróbia causando a inibição da metanogênese, implicando na produção do biohidrogênio (Chernicharo, 1997).…”

“…LIN e CHANG (2004) A grande maioria dos estudos realizados para a produção de hidrogênio utilizou águas residuárias sintéticas balanceadas de modo que as necessidades minerais dos microrganismos fossem supridas e os mesmos trabalhassem de forma otimizada. Assim, vários estudos utilizam na composição do afluente a sacarose (Kim et al, 2006;Wu et al, 2008) e glicose (Horiuchi et al, 2002;Lin et al, 2007;Shida, 2008;Turcot et al, 2008) como a principal fonte de carbono. Entretanto, alguns autores realizaram estudos com efluente industrial para a produção de hidrogênio, como por exemplo: efluente de indústria de refrigerante (Peixoto, 2008), vinhaça (Fernandes, 2008), glicerol (Seifert, et al 2007;Silva et al, 2009) e soro de leite.…”
