Fig 6. The effect of MIC of ammonia (0.105 and 0.524 M NH3; the equivalent of 1,468 and 7,340 NH3-N mg/L) on the survival of newly seeded MRSA43300 in digestate of week #13 poultry carcass aerobic decomposition.
Source of NH3 was (NH4)2SO4. Week #13 represents a late-phase of a complete aerobic digestion represented by lower microbial activity post the 99% reduction of BOD, TSS, and VSS. Data represents the mean log10 of measured concentrations of MRSA43300 of 4 aerobic reactors ± SD. Different letters in each treatment time indicate significant difference (p<0.05), n = 3.
