TLDR
Results indicated that NH2OH contributed to nitrite production, facilitating the maximum increase of nitrate (NO3--N) to NO2--N transformation ratio to 80.47 ± 2.82%, leading to 2.56-fold NO2-N higher than those of control.About:

Performance and Microbial Community Analysis of a Novel DEAMOX Based on Partial-Denitrification and Anammox Treating Ammonia and Nitrate Wastewaters
TL;DR: High-throughput sequencing analysis revealed that Thauera genera were dominant in both SBRs and possibly played a key role for partial-denitrification with high NO2--N accumulation and the Denitratisoma capable of complete denitrification (NO3--N→N2) was found in R2 that might lead to lower NTR.
