Palmer K, Drake HL, Horn MA. 2010. Association of novel and highly diverse acid-tolerant denitrifiers with N2O fluxes of an acidic fen. Applied and Enironmental Microbiology 76: 1125-1134.
These authors examined soils from an acidic fen in southern Germany, and discovered novel denitrifiers that are apparently adapted to local conditions and contribute to the cycling of nitrogen within the fen. Methods employed included measurement of soil parameters, microcosms to examine denitrification rates (both total denitrification and net production / consumption of N2O), cell counts of cultured organisms, and phylogenetic analysis using narG and nosZ sequences and RFLP.
