This work has shown the fluorescent antibody (FA) technique is a rapid and reproducible method for enumerating the levels of Nitrosomonas cells in coke-plant mixed liquor. The FA technique indicates that coke-plant mixed liquor contains about four orders of magnitude more Nitrosomonas cells than shown by MPN estimates. The FA technique indicates that Nitrosomonas comprises about 2% of the total cells in coke-plant mixed liquor at 25 day SRTs or greater and 1% at 4.2 day SRT. The nitrifying population in coke-plant mixed liquor has reserve capacity for oxidizing additional ammonia when treating moderate ammonia levels (approx. = 200 mg/l) at a 25-day SRT. The correlations between effluent ammonia and the population dynamics of Nitrosomonas indicate that the rate of ammonia removal in coke-plant mixed liquor is affected by both the number of nitrifiers and the activity per cell.
