Biogenic methane production is carried out by highly specialized, oxygen sensitive methanogenic archaea. Usually methanogenesis is therefore restricted to water-logged systems like freshwater sediments, rice field soils or gut systems (Ciais et al., 2014).Rivers as turbulent systems usually have well-aerated water bodies. dave and busters lynnwood jobs
