Nitrobacter NOB respond to environmental conditions by modulating their nitrite affinity, which highlights the importance of pre-culturing on experimental observations.
Surprising finding:
#Nitrobacter can dynamically modulate nitrite affinity in response to both nitrite concentration and pH, conferring a flexible adaptation strategy
Great collaboration with the Sung-Keun Rhee lab
