Assessment of a biogas-generating microbial community in a pilot-scale anaerobic reactor

Impact of the substrate loading regime and phosphoric acid supplementation on performance of biogas reactors and microbial community dynamics during anaerobic digestion of chicken wastes

“…They have been found in various anaerobic reactor systems (i.e. Ho et al, 2013;Ziganshina et al, 2014b). Since clostridia possess high cellulolytic activity, the impetuous increase of the Clostridium phylotype in reactors' samples might be due to the presence of high content of cellulosic biomass (bedding materials) in chicken wastes.…”

Metagenome changes in the mesophilic biogas-producing community during fermentation of the green alga Scenedesmus obliquus

“…Intensive studies of the microbial communities of maize silagefed anaerobic digesters Krause et al, 2008;Kröber et al, 2009;Jaenicke et al, 2011;Wirth et al, 2012;Stantscheff et al, 2014;Ziganshina et al, 2014) have demonstrated that, although the anaerobic fermentation conditions (fermenter size, feedstock composition, and origin, mixing, inoculum composition, etc.) differed somewhat, but the substrates were essentially the same (maize silage and pig manure) and coherent data sets could be collected.…”

Effect of the Organic Loading Rate Increase and the Presence of Zeolite on Microbial Community Composition and Process Stability During Anaerobic Digestion of Chicken Wastes

“…The second initially minor group (<1 % of the pyrotags) but found at high levels at the end point, when the TAN concentrations significantly increased, was the genus Clostridium. The different representatives of the hydrolytic order Clostridiales were also detected as dominant and abundant bacteria in different biogas systems [22,24,42,66,67]. Clostridia are strict anaerobes which have the ability to produce molecular hydrogen [7], and some species of Clostridiales can be effectively involved in cellulose biodegradation [10,68].…”
