Shortcut nitrogen removal holds significant economic appeal for mainstream wastewater treatment. Nevertheless, it is too difficult to achieve the stable suppression of nitrite-oxidizing bacteria (NOB), and simultaneously maintain activity ammonia-oxidizing (AOB). This study proposes overcome this challenge by employing novel acid-tolerant AOB, namely "Candidatus Nitrosoglobus", in a membrane-aerated biofilm reactor (MABR). Superior partial nitritation was demonstrated low-strength from two aspects. First, long-term operation (256 days) under acidic pH range 5.0 5.2 showed successful NOB washout situ free nitrous acid (FNA) approximately 1 mg N/L. evidenced nitrite accumulation ratio (NAR) close 100 % disappearance shown 16S rRNA gene amplicon sequencing fluorescence hybridization. Second, oxygen sufficiently supplied MABR, leading an unprecedentedly high ammonia oxidation rate (AOR) at 2.4 ± 0.1 kg N/(m
