a–c, Complete elimination of infectious viruses and the corresponding reduction in the genome count for Φ6 (a), H1N1 (b) and SARS-CoV-2 (c) when filtered through BLG AF–Fe membranes (blue, before filtration; grey, after filtration). A limited or no elimination was observed when filtering the same viruses through the cellulose support or the BLG AFs alone. The lower value of the genome count of Φ6 than that of the other two viruses is probably due to both a higher ratio of infectious viruses to genome count than those of the other two viruses and also the low efficiency of the genome extraction from these phages (Supplementary Table 2). Φ6 infectivity represents the plaque count from one plate of a series of dilutions that consist of at least three plates. A replicate of the Φ6 filtration experiment for which the infectivity was calculated using three technical replicas is shown in Supplementary Fig. 3. The genome count for Φ6 represents the average of four technical replicas and the error bars represent the standard deviation (s.d.). The infectivity and genome count of H1N1 as well as the genome count of SARS-CoV-2 represent the average of two technical replicas and the error bars represent the range. The infectivity of SARS-CoV-2 represents the average of four technical replicas and the error bars represent the s.d. LOD, limit of detection; *below the LOD. Representations of the virions are reproduced from pictures on ViralZone51.
