Extreme thermophilic biohydrogen production from arabinose and glucose
Abreu, A. A.; Karakashev, Dimitar; Angelidaki, I.; Sousa, D. Z.; Alves, M. M.Continuous hydrogen production rate from arabinose was significantly higher than from glucose, when higher organic loading rate was used. This fact was associated to higher lactate production in the reactor fed with glucose. The higher concentration of lactate was not a consequence of bacterial community shift, and is likely related to changes in the main metabolic pathways of glucose catabolism.
Biohydrogen production from arabinose and glucose using extreme thermophilic an...
Abreu, A. A.; Karakashev, Dimitar; Angelidaki, I.; Sousa, D. Z.; Alves, M. M.Background: Second generation hydrogen fermentation technologies using organic agricultural and forestry wastes are emerging. The efficient microbial fermentation of hexoses and pentoses resulting from the pretreatment of lingocellulosic materials is essential for the success of these processes. Results: Conversion of arabinose and glucose to hydrogen, by extreme thermophilic anaerobic mixed cultures was studie...
Engineered heat treated methanogenic granules : a promising biotechnological ap...
Abreu, A. A.; Alves, J. I.; Pereira, M. A.; Karakashev, D.; Alves, M. M.; Angelidaki, I.In the present study, two granular systems were compared in terms of hydrogen production rate, stability and bacterial diversity under extreme thermophilic conditions (70 °C). Two EGSB reactors were individually inoculated with heat treated methanogenic granules (HTG) and HTG amended with enrichment culture with high capacity of hydrogen production (engineered heat treated methanogenic granules – EHTG), respect...

Angelidaki, I.; Alves, M. M.; Bolzonella, D.; Borzacconi, L.; Campos, J. L.; Guwy, A. J.; Kalyuzhnyi, S.; Jenicek, P.; Lier, J. B. vanThe application of anaerobic digestion technology is growing worldwide because of its economic and environmental benefits. As a consequence, a number of studies and research activities dealing with the determination of the biogas potential of solid organic substrates have been carrying out in the recent years. Therefore, it is of particular importance to define a protocol for the determination of the ultimate m...
