Long-term preservation of anammox bacteria

Web9 de set. de 2016 · The anaerobic ammonium oxidation (anammox) process has mainly been applied to NH4+–N-rich wastewater with very low levels of organic carbon (<0.5 g COD per g N). Some anammox bacteria species have the capacity to oxidize organic carbon with nitrate as the electron acceptor. However, little is known about the organo Web15 de jun. de 2014 · Rothrock et al. (2011) have reported that pre-freezing with liquid nitrogen (−200 °C) was required for long-term preservation of anammox bacteria via lyophilization. Recently, Magri et al. (2012) preserved anammox biomass immobilized in polyvinyl alcohol (PVA) gel at −8 °C for 17 h but anammox activity was severely damaged.
