The methane-generating ammonia-oxidizing 16S rRNA gene abundances in the tanks for production systems fitted with bio-filters. The figure represents the average CFU values and standard deviations of 3 replicates (p < 0.05) for Ctrl, LsB, PsB, and EsB respectively, showing abundance values for samples obtained after real-time qPCR analysis tests in the months of July, August and September 2017
