The need to pre-treat lignocellulosic biomass prior to dark fermentation results primarily from the composition of lignocellulose because lignin hinders the processing of hard wood towards useful products. Hence, in this work a two-step approach for the pre-treatment of energy poplar, including alkaline pre-treatment and enzymatic saccharification followed by fermentation has been studied. Monoethanolamine (MEA) was used as the alkaline catalyst and diatomite immobilized bed enzymes were used during saccharification. The response surface methodology (RSM) method was used to determine the optimal alkaline pre-treatment conditions resulting in the highest values of both total released sugars (TRS) yield and degree of lignin removal. Three variable parameters (temperature, MEA concentration, time) were selected to optimize the alkaline pre-treatment conditions. The research was carried out using the Box-Behnken design. Additionally, the possibility of the re-use of both alkaline as well as enzymatic reagents was investigated. Obtained hydrolysates were subjected to dark fermentation in batch reactors performed by Enterobacter aerogenes ATCC 13048 with a final result of 22.99 mL H2/g energy poplar (0.6 mol H2/mol TRS).

“…Thereby, in order to propose the application of a waste material for energy recovery it is essential to conduct a previous assessment of the most suitable operational conditions for the desired conversion process. In case of dark fermentation process, besides the concentration of carbohydrates, factors such as reactor setup, temperature, pH, period of fermentation, source of inoculum, as well as its hydrogen-producing bacteria (Hu et al, 2013) play key roles in an efficient H 2 production, with emphasis on the type of inoculum and its pretreatment procedure (Mohan et al, 2007).…”

“…This low COD removal efficiency, rather than being a problem, might represent a strategy to improve the treatment of industry wastewater through a two-stage process of fermentative hydrogen production. In this case, the effluent of acidogenic stage composed mainly be VFA and alcohols could be further employed as substrate for methane generation (Peixoto et al, 2012), photofermentation (Eroglu et al, 2006 andHu et al, 2013) or even for biotechnological applications such as microalgal cultivation (Ren et al, 2014) and biodiesel production by oleaginous yeast (Singhania et al, 2013).…”

“…Hydrogen is considered a promising energy source for the future due to its renewability, as well as for its clean end of usage. It has greater energy contents per unit of weight (142.35 kJ g À1 ; 2.75 times) (Khamtib and Reungsang, 2014) in comparison to hydrocarbon fuels (Hu et al, 2013), and since water is the only by-product generated by its combustion, hydrogen is an alternative energy source more sustainable than fossil fuels (Guo et al, 2010). However, to make it competitive with conventional energy carriers, ensuring its sustainable benefits, further technological advancements (Kumar et al, 2016) as well as the improvement of practical and scientific knowledge are essential.…”

“…Dark fermentation is an environmental feasible process due to its simultaneous waste treatment and hydrogen production and is advantageous because of its high production rate with a low energy input (Liu et al, 2011), and because of the versatility in the use of carbohydrate-containing substrates as agricultural wastewater, food waste, domestic wastewater, industry wastewater, among others (Hu et al, 2013 andKhamtib andReungsang, 2014). It may be a suitable alternative for energy production in small-scale from industrial plants with highly available and lowcost biomass (Das and Veziroglu, 2008), providing a low-cost local energy supply.…”

Potential of biohydrogen production from effluents of citrus processing industry using anaerobic bacteria from sewage sludge

et al. 2017

Citrus crops are among the most abundant crops in the world, which processing is mainly based on juice extraction, generating large amounts of effluents with properties that turn them into potential pollution sources if they are improperly discarded. This study evaluated the potential for bioconversion of effluents from citrus-processing industry (wastewater and vinasse) into hydrogen through the dark fermentation process, by applying anaerobic sewage sludge as inoculum. The inoculum was previously heat treated to eliminate H-consumers microorganisms and improve its activity. Anaerobic batch reactors were operated in triplicate with increasing proportions (50, 80 and 100%) of each effluent as substrate at 37°C, pH 5.5. Citrus effluents had different effects on inoculum growth and H yields, demonstrated by profiles of acetic acid, butyric acid, propionic acid and ethanol, the main by-products generated. It was verified that there was an increase in the production of biogas with the additions of either wastewater (7.3, 33.4 and 85.3mmolL) or vinasse (8.8, 12.7 and 13.4mmolL) in substrate. These effluents demonstrated remarkable energetic reuse perspectives: 24.0MJm and 4.0MJm, respectively. Besides promoting the integrated management and mitigation of anaerobic sludge and effluents from citrus industry, the biohydrogen production may be an alternative for the local energy supply, reducing the operational costs in their own facilities, while enabling a better utilization of the biological potential contained in sewage sludges.
