	abstract = {Performance and molecular changes of an aerobic denitrifying phosphorus accumulating bacteria Pseudomonas psychrophila HA-2 have been investigated under different temperatures and ZnO nanoparticles (NPs) exposures. Strain HA-2 removed 95.7\% of total nitrogen (TN) and 24.6\% of phosphorus at 10{\textdegree}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{\textdegree}C, respectively, whereas phosphorus removal rate increased from 10.5\% to 24.5\% at 20{\textdegree}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{\textdegree}C, while the up-regulation of antioxidant pathways and functional genes expressions was responsible for the promoted phosphorus accumulation at 20{\textdegree}C. This study provides a potential solution for improving biological nutrients removal processes in winter months.},
