     bioaugmentation with an enriched microbial population was applied in an aerobic sequencing batch reactor (sbr) receiving transient or continuous shock loads of p-nitrophenol (pnp). the effect of the amount of biomass added for bioaugmentation was assessed by using two different dosages (2% or 5% w/w of the total biomass in the seeded sbr). in both cases, total pnp removal was achieved during the transient pnp shock load occurring after bioaugmentation. however, after a long pnp starvation period the only experiment still showing total pnp removal during a second pnp shock load was the one where a dosage of 5% w/w was applied. the results suggested that the dosage is a key factor for the implementation of a successful bioaugmentation strategy. in addition, the performance of a bioaugmented sbr receiving a continuous pnp shock load was enhanced when compared to a non-bioaugmented sbr.
