The stress response of ammonia-oxidizing bacteria (AOB) to oxygen deprivation limits AOB growth and leads to different nitrification pathways that cause the release of greenhouse gases. Measuring the stress response of AOB has proven to be a challenge due to the low growth rates of stressed AOB. making the sample volumes required to monitor the internal stress response of AOB prohibit... https://www.roneverhart.com/Oakley-Fives-4-0/
