摘要: Anaerobic ammonium oxidation (anammox) is the microbial of with nitrite to dinitrogen gas under strict anoxic conditions mediated by planctomycete-like bacteria. Anammox not only important in oceanic nitrogen cycle, but can also contribute substantially removal municipal and industrial wastewater treatment. This chapter addresses enrichment cultivation anammox bacteria a sequencing batch reactor (SBR) lift reactor. The reactors be operated anoxically as an or oxygen-limited "completely autotrophic over nitrite" (CANON) system. Pure cultures organisms have yet been obtained, cells purified more than 99.5% using Percoll density gradient centrifugation protocol. Furthermore, we show how communities natural man-made ecosystems identified characterized molecular methods such fluorescence situ hybridization (FISH) Planctomycetes/anammox-specific polymerase chain reaction (PCR). Both techniques are based on retrieved 16S rRNA gene sequences. In addition rRNA, unique ladderane lipids serve biomarkers determine abundance environmental samples.
