This document summarizes research on developing an ammonia scrubber system for poultry and swine facilities that uses acid-tolerant nitrifying bacteria to generate the acid needed to capture ammonia. Key points: 1) The researcher developed acid-tolerant nitrifying bacteria that can generate acid via nitrification at low pH levels. 2) This bacteria was used to inoculate an ammonia scrubber, which successfully captured ammonia using the acid produced by the bacteria. 3) However, the bacteria only thrive at warm temperatures, so further research is needed to develop strains that can also tolerate colder conditions to make the system practical year-round.
