CuO NPs and bulk CuO were purchased from Shanghai Jingchun Reagent Limited Company, China. CuO NPs, with the purity is greater than 99.5 %, particle diameter is 40 nm and a surface area is 25–40 m2 g−1.The purity of bulk CuO is more than 99.9 %, particle diameter is 10 μm. The morphology of the CuO NPs was examined by transmission electron microscopy (TEM, JEOL 100CX, Japan). The particle diameter of CuO NPs in solution and the zeta potential of CuO NPs and bulk CuO in solution were measured using a 90 plus particle size analyzer (DR-525, Brookhave Instruments Corporation, USA) at 12 h after media preparation. The Cu2+ concentration that the nano-CuO released to the culture media was measured by ICP-MS 7500ce, Agilent, USA at 24 h after media preparation.

300 mg of composite or ACFs was placed in a specially designed cartridge (details given in ESI† ), and cut glass fiber filters (0.4 μm, Macherey–Nagel) were placed in the inlet and outer caps of cartridge to avoid the release of fibers from the system. The prepared cartridge was rinsed with 0.01 M NaCl solution with the pH adjusted to 5.0 and 7.0 for 24 h at a flow rate of 150 mL h−1. Permeate samples were regularly collected and the concentration of copper in permeate was analyzed via ICP-MS (ICP-MS 7500 CE, Agilent). All tests were performed in duplicate.

R1, Qpr6 KD, and Qpr6 Com strains were cultured to OD600 of 0.8 in 100 ml TGY media. The E. coli K-12 strain was cultured to OD600 of 0.4 in 50 ml LB media. The cells were then harvested by centrifugation at 10,000 g, 4°C for 10 min. The pellets were washed three times with 1 × PBS containing 1 mM EDTA and rinsed three times with 1 × PBS containing no EDTA. After centrifugation, the pellet was dried at 80°C for ~24 h, and the cell dry weight was measured. The cells were then resuspended in 2 ml of 30% nitric acid (GFS Chemicals) and incubated at 80°C for 4 h. After centrifugation at 12,000 g for 20 min, the supernatant was filtered against a 0.45 μM membrane (VWR) and serially diluted with ionized water to make the final concentration of nitric acid to 2%. The Mn2+ and Fe2+ concentrations were then measured using inductive coupled plasma mass spectrometry (ICP-MS 7500ce, Agilent). A blank control was prepared in the same manner but without cells. All data were replicated three times, and the means were used as representative values.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
