Fig. 4: Virus–host profiles of functional microorganisms in WWTPs.

a Virus–host profiles of functional microorganisms related to aerobic oxidation. b Virus–host profiles of functional microorganisms related to the anaerobic process. c Virus–host profiles of functional microorganisms related to nutrient removal (N, P, S). The size of the circle indicates the number of viral genera that could infect the corresponding microbial genera. Source data are provided as a Source Data file.
