Physiological and transcriptomic response of enriched anammox culture upon elevated hydrazine exposure.

ABSTRACT: Anammox has emerged as a cost-effective and eco-friendly biological treatment technology for high-strength wastewater, and hydrazine (N₂H₄) is a unique intermediate in the anammox metabolism. This study presents the first investigation into the genetic responses of anammox bacteria to elevated N₂H₄ concentrations, offering critical insights into their potential for sustainable environmental applications. In this scope, anammox cultures were exposed to high levels of N₂H₄ (up to 3 g/L) over a short-term period to evaluate their nitrogen treatment capacity and transcriptional responses. The results indicated that anammox activity continued at N₂H₄ concentrations of 1.88 g/L or less. However, acute N₂
