“…Basically, this construction is described by extended start-up phase [52,53] since the flocculation of bacterial communities in the sludge-bed demands longer time. However, start-up period of granular systems for biohydrogen generation could be considerably shortened through the transformation of methanogenic granules (obtained e.g.…”

“…Additionally to HRT, altering organic loading rate (OLR) is also a stress source to the strains that are forced to get accustomed to new surroundings [52]. Varying OLR might cause sporulation in hydrogen producing cultures and contribute to the observable fluctuations in the H 2 production efficacy during start-up stage [48,67].…”

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.

“…It is important to mention here that with pH values lower than 5 or higher than 6, the methanogenesis rate decreases or stops according to explanations of Chang and Lin (2004) and Yang et al (2006). Consequently, in the present study it was concluded that the use of pH value of 5.5 prevents hydrogen reduction and produces dominant microbes for hydrogen production from wastewater.…”

“…The thermal pretreatment was selected as 80°C and 30 min of treatment time. This type of the pretreatment is important to be ensuring from killing all undesirable bacteria (aerobic bacteria) (Wang et al, 2003;Chang and Lin, 2004). After sterilizing, the pretreated sterilized compost sample was cooled to ambient temperature and treated with 0.5 ml of nutrient solution and then was used in experiments.…”

Problem statement:Hydrogen is a clean energy source. Bio-conversion of biomass to generate hydrogen has been achieved using anaerobic fermentation of some well-defined materials, in wastewater. No data available on hydrogen yielded from wastewater using inoculum extracted from Iraqi municipal wastewater treatment plant. Approach: This study investigated the effects of substrate concentration, initial pH and process temperature on biohydrogen production from surgery wastewater using anaerobic batch reactor. Batch tests are carried out in a 2.0 L batch reactor under different temperatures of 34, 36, 38and 40°C, various initial pH of 4.5, 5.5 and 6.5 and substrate concentrations of 5, 10 and 15%. The raw seed was compost sludge obtained from municipal wastewater treatment plant in Baghdad (Al-Restomia plant). The volume of evolved gas was measured at room temperature by the water displacement method. Results: The maximum hydrogen production 160 mL L −1 is obtained at an optimum temperature of 38 °C, optimum pH of 5.5 and substrate concentration 15%. Conclusion:The results indicated that the use of compost of Al-Restomia plant as a seed in anaerobic fermentation process has given excellent biogas production under applied conditions.
