Taxonomic distribution in Salmonella dilution series (SDS) after removal of Decontam contaminants (frequency-based). 58 out of 235 operational taxonomic units (OTUs) in the dataset were identified as contaminants and removed (user defined threshold = 0.5). At the default threshold, only 9 out of 235 OTUs in the dataset were identified as contaminants (figure not drawn). Taxonomic rank is described using prefixes (c__: class, o__: order, f__: family, g__: genus). Data unrarefied
