The ACTIONr team participated in the Joint Conference of the MikroBioKosmos Society & the Central and East Europe Symposium of Microbial Ecology (MBK-CEESME 2025) in Thessaloniki, 22–24 September 2025. We presented new findings on nitrification inhibitors (SNIs/BNIs) and the soil nitrogen cycle, spanning environmental fate and time-series multi-omics of nitrifiers.

Invited talk:

• Prof. Christa Schleper (Genetics and Microbiology, University of Vienna) delivered an invited lecture:
  “What Asgard Archaea can tell us about early eukaryotic evolution.”

Other contributions:

• Here today, gone tomorrow? Persistence and dissipation of five plant-derived BNIs across ten agricultural soils; DT50 from hours to weeks, shaped by pH and microbiota. (E. Papadopoulou, C. Moutzourelli et al.; poster presentation)
• Let the inhibitor out of the flask: Culture–soil disparities; BNI efficacy drops in soil microcosms versus pure cultures. (C. Moutzourelli et al.; oral presentation)
• Plant triterpenoids as novel BNIs (archaeal selectivity): 18 triterpenoids show strong AOA selectivity and limited impact on AOB. (H. Ribeiro et al.; poster presentation)
• Disrupting soil nitrification: Time-resolved transcriptomics/proteomics in Nitrososphaera viennensis reveal rapid (≤0.5 h) transcriptional and delayed (~6 h) proteomic responses to seven NIs. (D. Dalkidis et al.; flash talk)
