Strain HA-2 removed 95.7% of total nitrogen (TN) and 24.6% of phosphorus at 10°C, which was attributed to the joint up-regulation of intracellular energy metabolism and ribosome. Moreover, with the increase of ZnO NPs from 0 to 100mg/L, TN and phosphurs removal efficiencies decreased from 95.7% to 44.5% and 24.6% to 6.8% at 10°C, respectively, whereas phosphorus removal rate increased from 10.5% to 24.5% at 20°C. Further transcriptomics and proteomics revealed that significant down-regulation of purine and amino acid metabolisms was the main reason for the inhibitory effect at 10°C, while the up-regulation of antioxidant pathways and functional genes expressions was responsible for the promoted phosphorus accumulation at 20°C. This study provides a potential solution for improving biological nutrients removal processes in winter months.</style></abstract><accession-num><style face="normal" font="default" size="100%">MEDLINE:35429594</style></accession-num><notes><style face="normal" font="default" size="100%">Times Cited: 01873-2976</style></notes></record></records></xml>
