Additional file 3 of Microbiota of the indoor environment: a meta-analysis

Figure S3. Cyanobacteria. Example of taxonomic bias observed in technical control samples compared to environmental samples for taxa likely to be present in environmental samples. The composition of each of the pooled (a) dust and (b) kit controls is shown as a donut. The dust composition displayed higher abundances of Cyanobacteria (blue slice in donut chart indicated by arrows.) Per-sample abundance of Cyanobacteria is represented by blue bars displayed across all panels. Donut and bar charts were generated using the Phinch data visualization framework [63]. (PDF 146 kb)
