“…Despite the variation in volume, the percentage of hydrogen in the biogas during the application of the OLR of 15; 26; 28 and 35 g.L -1 .d -1 had few variations, ranging from 18.6% to 22%; values lower than 15% were observed for the OLR of 22 and 27 g.L -1 .d -1 . The composition of the biogas was similar to the results noted by AMORIN et al (2009) andTHANWISED et al (2012), who obtained percentages of hydrogen of 25% and 11.65% in HRT of 4 and 3h, using sucrose and cassava-processing wastewater as substrates, respectively. ; however, the consumption of sugars remains constant.…”

“…The COD removal efficiencies remained under the values expected in fermentative systems for hydrogen production in reactors fed with cassava-producing wastewater at between 20% and 50% (SREETHAWONG et al, 2010;THANWISED et al, 2012). The removal efficiencies may have been influenced by the low C/N ratio in wastewater.…”

“…Apart from the organic loading rates, higher initial pH values (6.0) may make the environment favourable to the rapid formation of acids and as a result, may reduce the pH of the environment (KHANAL et al, 2004 (Table 3). In reactors with dominance of acidogenic bacteria, COD is removed through cytogenesis and gas releases (mainly H 2 and CO 2) , while a significant amount is converted into intermediate products, such as acids and solvents that remain in the system (THANWISED et al, 2012).…”

Attempting to associate waste treatment to the production of clean and renewable energy, this research sought to evaluate the biological production of hydrogen using wastewater from the cassava starch treatment industry, generated during the processes of extraction and purification of starch. This experiment was carried out in a continuous anaerobic reactor with a working volume of 3L, with bamboo stems as the support medium. The system was operated at a temperature of 36°C, an initial pH of 6.0 and under variations of organic load. The highest rate of hydrogen production, of 1.1 L.d-1.L-1, was obtained with application of an organic loading rate of 35 g.L-1.d-1, in terms of total sugar content and hydraulic retention time of 3h, with a prevalence of butyric and acetic acids as final products of the fermentation process. Low C/N ratios contributed to the excessive growth of the biomass, causing a reduction of up to 35% in hydrogen production, low percentages of H2 and high concentrations of CO2in the biogas.

“…The adaption of H 2 producing microflora to a given substrate can be conducted in complex and multistep batch operation, where bacterial consortia are periodically supplied with gradually increasing feed concentrations before putting into continuous mode [64]. Nevertheless, as mentioned above, there are studies that skipped preliminary batch operation and adapted the H 2 generating cultures during continuous operation.…”

a b s t r a c tThe start-up of continuous biohydrogen fermentations is a complex procedure and a key to acceptable hydrogen production performance and successful long-term operation. In this review article, the experiences gained and lessons learned from relevant literature studies dealing with various aspects of H 2 producing bioreactor start-up are comprehensively surveyed. Firstly, the importance of H 2 -forming biosystem start-up including its main steps is outlined. Afterwards, the role of main influencing factors and methods (e.g. strain selection, seed pretreatment and inocula stimulation, switch-over time, bioreactor design, operating conditions) in avoiding the deterioration of starting a reactor is analyzed and presented in detail. Finally, the so far suggested applicable start-up strategies and the corresponding findings are critically discussed pointing out the advantages and disadvantages of each strategy.
