Capture of Methane by Fungi: Evidence from Laboratory-Scale Biofilter and Chromatographic Isotherm Studies

Abstract

ABSTRACT. Livestock production accounts for a third of total U.S. anthropogenic methane (CH 4

A comparative assessment of the performance of fungal-bacterial and fungal biofilters for methane abatement

“…The higher EC obtained in the FBB operated in this study may be explained by the increase in the interfacial gas-biofilm contact area due to the presence of the filaments from fungi [30] and by the increase in the CH4 concentration gradient mediated by the hydrophobic properties of the fungal filaments [11,31]. These fungal mediated mechanisms could increase the bioavailability of methane in the whole methanotrophic biofilm, which ultimately supported higher CH4 degradation rates [14]. The later highlights the advantage of deploying methanotrophic fungal/bacterial consortia during CH4 biofiltration [11].…”

“…The potential of fungi as a biological platform for enhancing the availability and biodegradation of methane has been reported by several authors [11][12][13][14]. Girard et al [12] inoculated the fungi Candida ingens, Sporotrichum pruinosum, Coprinus sp.…”

Climate Change: A Call for Adaptation and Mitigation Strategies

“…An effective climate-change mitigation strategy must include reduction in emission of greenhouse gases (GHGs), including methane. Oliver and Schilling (2016), using a lab-scale biofilter, show that several fungal species are capable of capturing methane from livestock operations. The authors conclude that GHG emission from livestock operations can be considerably mitigated.…”

Effect of Cubicle Hood System on Methane Concentrations Around the Lying Area in Cold Climate Dairy Cattle Buildings

“…Likewise, pilot studies indicate biofiltration as a potential low-cost CH 4 abatement technique in the livestock sector (Fedrizzi et al, 2018, Oliver and Schilling, 2016, Melse and Van Der Werf, 2005. This is because, in contrast to catalytic CH 4 treatment, which require complex combustion units with higher operating temperatures (> 400 • C) and inlet CH 4 concentrations (> 5000 ppm) to effectively function (He et al, 2020), biofiltration systems are easier to design and can function at ambient temperature (< 30 • C), atmospheric pressure, and relatively low inlet CH 4 concentrations (Melse and Hol, 2017).…”
