2n denotes the number of RSCVs isolated in a random sample from the reactor, and a denotes the number of those RSCVs that had the indicated RSCV-linked allele, which was determined by targeted sequencing of the allele in each isolate. Allele frequency in the biofilm population, therefore, was estimated as the ratio of a/n.
