“…2). It has been reported that low concentrations of CH 4 were the main cause for the decreased activity of methanotrophs (Visscher et al, 1999;Ai-Benichou et al, 2009). However, a further increase in CH 4 concentration from 10% to 30% had no significant effect on CH 4 oxidation potential.…”

“…Methylocaldum, Methylobacter, Methylomonas, Methylomicrobium, and Methylosarcina were identified among the type I bacteria (Wise et al 1999;Bodrossy et al 2003;Ait-Benichou et al 2009). The presence of type II Methylocystis and Methylosinus has also been reported (Wise et al 1999;Bodrossy et al 2003;Kallistova et al 2007).…”

Biofiltration of methane and trace gases from landfills: A review

et al. 2012

View full text Add to dashboard Cite

Concerns about biogas from landfills are reviewed in terms of biogas generation, composition, and elimination. Biogas is mainly composed of methane and carbon dioxide but it also contains a few hundred non-methane organic compounds. The solutions available to reduce its harmful effects on the environment and on human health are valorization as electricity or heat, flaring, or biofiltration. The main parameters affecting the biofiltration of methane are reviewed: temperature, moisture content, properties of the packing material, nutrient supply, oxygen requirements, formation of exopolysaccharides, and gas residence time. An analysis is performed on the co-metabolic properties and the inhibition interactions of the methane-degrading bacteria, methanotrophs.

“…So far, more than 15 different methanotrophic genera were isolated from various environmental sources including marine (Schubert et al, 2006;Wang et al, 2007;Tavormina et al, 2010;Hirayama et al, 2012); landfills (Uz et al, 2003, Stralis-Pavese et al, 2004, Benichou et al, 2009; rice fields (Eller et al, 2001, Macalady et al,2002, Eller et al, 2005, Horz et al, 2005Geymonat et al, 2011); forest soils (Henckel et al, 2000a;Dunfield et al, 2003, Jaatinen et al, 2004, Lau et al, 2007, Dunfield, et al, 2010Jang et al, 2011;Iguchi et al, 2011); coal mines (Han et al, 2009, Wolinska et al, 2013; compost/manures/biosolids stock piles (Herrmann and Shann, 1997, Jackel et al, 2005, Halet et al, 2006Kim et al, 2008;Nielsen et al, 2013); peat bogs (Dedysh et al, 2000;Dedysh et al, 2007;Vorobev et al, 2011;Kip et al, 2011); wetlands, lakes, and fresh water sediments Rahalkar et al, 2009;Deutzmann et al, 2011); as well as extreme environments, such as hot aquifers, soda lakes, oil tailing ponds, alpine meadows, and submarine volcanoes, etc. (Heyer et al, 2005;Tsubota et al, 2005;Losekann et al, 2007;Hirayama et al, 2011;Zheng et al, 2012;…”

Biological methane (CH 4 ) mitigation combined with biopolymer (PHA-polyhydroxyalkaonate/PHB-polyhydroxybutyrate) production is a viable option in this fossil fuel-constrained era.Methantrophs are bacteria that can re-route CH 4 into PHA/PHB under nutrient-starved conditions. However, most studies (up to 90%) investigated pure cultures to demonstrate capacity for PHA/PHB accumulation, which on an industrial scale is unlikely to be serviceable. Furthermore, commercialization is handicapped as there are still a number of unresolved issues which affect productivities, such as optimized process variables, characterization of robust consortia, and optimized reactor design. This review will summarize existing knowledge and highlight research needs to fast track methanotrophic PHA/PHB production from CH 4 .
